Entering the NanoTerasu Building

NanoTerasu uses a “facial recognition system” for building access management. Pre-registration of facial recognition data is required to gain entry.

Entry Management for Experiment Leaders and Co-Experimenters

  • ※ Users can access the Entrance, Sub-Entrance, elevator, Experimental Hall, and some surrounding rooms (such as the experiment preparation room) using facial recognition.
  • Registering facial recognition data alone does not grant access to the building. Please complete the following additional procedures:
    [Public BL Users]: The Experiment Leader must submit a usage application form by referring to the NanoTerasu User Information provided by JASRI.
    [Coalition BL Users]: Please make a reservation through the Beamtime Reservation Management System.
  • First-time users of facial recognition for NanoTerasu entry must visit during working hours when NanoTerasu staff are available (weekdays from 9:00 to 17:30) to verify proper recognition. Please enter through the main entrance at the time.
  • If the automatic door does not unlock via facial recognition, please contact the Users Office or the Central Monitoring Office using the intercom next to the entrance door.
    • NanoTerasu staff will verify the registered information and process the entry.
    • If the registration information cannot be confirmed, entry may be denied.
  • Any experiment participant (Experiment Leader or Co-Experimenter) entering NanoTerasu without facial recognition is strictly prohibited.

Building Entry and Room Access Procedures

  1. First, perform facial recognition using the camera next to the automatic door. Please make sure to hold your face close to the camera for recognition.
  2. Once identity is confirmed, the blue LED turns green, and the automatic door unlocks, please proceed inside.
  3. Exit and departure do not require facial recognition; the doors will open automatically.

Facility Tours and Experiment Observations

  • To use NanoTerasu, individuals must be registered as either a Radiation Worker or a Non-Radiation-Controlled Area BL User (Radiation Handler).
  • There are two types of tours: general facility tours for the public and experiment observations for experiment-related personnel.

Facility Tours

  • If members of the general public (who are not part of an experiment group) wish to visit NanoTerasu, they should refer to the NanoTerasu Facility Tour Application.
    Note: Facility tours only include the designated Tour Hall. Access to the Experimental Hall is not permitted.

Experiment Observations

  • If an experiment group member (observer) who is NOT registered as a Radiation Worker or a Non-Radiation-Controlled Area BL User (Radiation Handler) wishes to enter the Experimental Hall for observation, preliminary inspections, participation, or discussions with involved personnel, they must apply for Visit to the Experimental Hall. See Experiment Observations (Entry to Experimental Hall Only) for details.
  • If an observer also needs to enter an Experimental Hutch, they must apply for a Temporary Access to Radiation-Controlled Areas. See Experiment Observations (Entering Experimental Hutch) for more information.

Safety

Basic Safety Considerations

Compliance with Laws and Regulations

  • When conducting work at NanoTerasu, all users must comply with laws and regulations, and the rules established by NanoTerasu, always prioritizing safety and health.

SWA (Stop Work Authority)

  • If hazardous or unsafe behavior is observed, NanoTerasu staff may order the suspension of the work.
  • All users must take immediate action if they witness dangerous or unsafe behavior by either warning the individual directly or reporting it to nearby NanoTerasu staff or the Users Office.

Principles of Emergency Response

In the event of a disaster, accident, injury, or medical emergency, the following three principles must be followed:

  1. Priority of Human Life
    Always prioritize the safety of human life and well-being.
  2. Alert and Report
    Inform those nearby about the emergency and follow the designated emergency reporting procedures.
  3. Prevention of Spread of Damage
    First, ensure your own safety, and then, if possible, take measures to prevent further escalation of the damage or the abnormal situation in its early stages.

Hygiene and Orderliness

  • Users must maintain cleanliness and orderliness in their work areas.

Avoiding Solo Experiments and Preventing Accidents Due to Fatigue

  • Do not conduct experiments alone.
  • Ensure sufficient sleep and rest during your time at NanoTerasu. Do not conduct experiments when feeling unwell or mentally fatigued.

Hazard Awareness and Consideration for Others

  • Before conducting an experiment, carefully assess the potential hazards associated with the equipment, tools, and work conditions.
  • If a hazard is identified, take preventive measures such as wearing protective gear. Use signs, warnings, and restricted access areas to alert others to potential hazards.

Access Restrictions

  • As a rule, users are not allowed to enter the inner areas of the Linac Building and the Storage Ring Building beyond the Experimental Hall, including the area above the Accelerator Tunnel.
  • Although the Experimental Hall (excluding the inside of beamline hutches) is not designated as a radiation-controlled area, a caution zone may be established using barricade ropes or similar measures if elevated radiation levels are expected due to accelerator or beamline adjustments. Only NanoTerasu Radiation Workers are permitted to enter radiation-controlled areas or caution zones; others must not enter without authorization.
  • Do not enter areas with warning or caution signs unless authorized.

Clothing and Footwear

  • To prevent accidents and injuries, avoid inappropriate clothing and footwear.
    • (Examples: Do not wear shoes that are loose-fitting or slippery; avoid exposing unnecessary skin.)

Work Notification

  • If a user or a contractor hired by the user plans to carry out work that involves significant risks—such as transporting or moving large equipment, working at heights, or using cranes, open flames, or electrical panels—a Work Notification Form must be submitted in advance using the designated format. Please contact JASRI, PhoSIC or the Users Office for more information.

Emergency Responses

Emergency Contact Procedures

  • (1) When an Injury or Medical Emergency Occurs
    If an individual suffers an injury or a sudden health issue and requires an ambulance, dial 119 to contact the fire department directly. Be sure to clearly state that the incident occurred at NanoTerasu and provide details of the situation. After completing the emergency call, immediately report the ambulance dispatch to the Central Monitoring Office at 022-721-5180.
  • (2) In Case of Fire
    If a fire or other emergency occurs, immediately call the Central Monitoring Office at 022-721-5180. The Central Monitoring Office will handle the notification to the fire department.
  • (3) Important Points When Making an Emergency Call
    • Stay calm and clearly provide:
      • Your name and contact information
      • The location within NanoTerasu where the emergency is occurring
      • A brief description of the situation
    • Do not hang up until instructe do to do so.
      Note: After reporting to the fire department or the Central Monitoring Office, if possible, notify the person in charge of the BL as well.

Emergency Evacuation Locations

  • In the event of a disaster, fire, or accident, follow instructions from the public address system and evacuate immediately if necessary.
  • At the evacuation site, follow the instructions of NanoTerasu staff.
  • The main evacuation locations are:
    • Parking lot in front of the Main Entrance
    • Parking lots in front of each Sub-Entrance
    • Roads around each emergency exit

Personnel Accountability

  • The Experiment Leader must be able to communicate with Co-Experimenters, the Users Office, and person in charge of the BL as well at all times during their NanoTerasu usage period.
    Note: In the event of a large-scale disaster or fire, the Experiment Leader may be asked to report the safety status of their experiment group members.

Fire Response

If a fire occurs, report it immediately to the designated contact points. If it is safe to do so, attempt initial fire suppression within your capabilities.

  • When a fire is caused by Electrical Equipment, first, cut the power to the burning equipment.
  • Do not use water to extinguish electrical fires. Use the provided dry powder fire extinguisher.
  • If you are not involved in fire suppression, evacuate immediately to the designated evacuation site.

Earthquake Response

If you feel a strong tremor, follow the steps below: Note that NanoTerasu is designed to withstand earthquakes as strong as the Great East Japan Earthquake (2011). Remaining inside the facility is generally the safest option.

  • Stay calm and prioritize personal safety.
  • Move away from areas where objects might fall or collapse.
  • Take cover under a sturdy table or similar structure.
  • Once the shaking stops,
    • Check for fires and extinguish them if necessary.
    • Provide first aid to injured individuals.
  • If an evacuation order is issued, follow instructions and proceed calmly to the designated evacuation site.
  • Do not use elevators.

Radiation Accident Response

If any of the following radiation-related incidents occur, immediately contact the Central Monitoring Office and follow their instructions:

  1. Loss or theft of re-used radioactive materials or sealed radioactive sources.
  2. Unplanned radiation exposure exceeding:
    • 1 millisievert for Radiation Workers,
    • or 0.1 millisieverts for non-radiation workers,
    • or cases where such exposure is likely (includint unauthorized entry into restricted areas such as the Accelerator Tunnel or beamline hutches).

Note:
If the shutter is opened to synchrotron radiation is introduced into the Experimental Hutch while a dosimeter has been left inside, immediately contact the person in charge of the BL or the Radiation Safety Office, and the user of that dosimeter must not enter the Experimental Hutch until further instructions are given

Chemical Accidents Response

  • Before bringing chemicals or reagents into NanoTerasu, review their Safety Data Sheets (SDS) to ensure you understand their properties, and prepare emergency supplies in case of accidental exposure or injury.
  • If an incident occurs, follow the same emergency contact procedures as for medical emergencies.
  • Even if first aid is administered, immediately notify the Central Monitoring Office.
    Note: Emergency showers are located near the Central Control Room in the Experimental Hall, Sub-Entrance 2, and Equipment Maintenance Room 1.

Oxygen Deficiency Accident Response

Inert gases themselves are not harmful but can cause oxygen deficiency when they accumulate in an enclosed space. Oxygen levels in the air correlate with symptoms as follows:

Oxygen Level [%]Effects
21Normal air composition
18Safety limit, but requires continuous ventilation
16Headache, nausea
12Dizziness, muscle weakness
8Loss of consciousness, death within 7–8 minutes
6Immediate coma, respiratory failure, death
  • If You Discover a Person Suffering from Oxygen Deficiency:
    • Call out loudly for help.
    • Open the room door or otherwise ventilate the area to allow air exchange with the outside, and do not enter the room until it has been confirmed that the oxygen concentration is sufficient using an oxygen monitor.
    • To avoid becoming oxygen-deficient yourself, hold your breath and pull the affected person out of the room.

Take the above measures and report the incident as you would in the event of an injury or medical emergency.

  • To prevent secondary accidents, do not attempt solo rescues if the situation is prolonged.
  • Be cautious when handling liquid nitrogen or other cryogenic gases in Experimental Hutches or surrounding rooms.

Other Important Notes

  1. In general, when injuries require immediate medical attention by a doctor—such as burns larger than the size of a palm, heavy bleeding, bone fractures, impaired or lost consciousness, or respiratory or cardiac arrest—the injured person must be transported to a medical facility by ambulance.
  2. If the head is struck hard, you must receive a medical evaluation at a healthcare facility, regardless of the presence or absence of external injuries or signs of consciousness disturbance.
  3. In the event of emergency transport, a colleague involved in the same experiment should accompany the injured person, and arrangements must be made to ensure communication with both the person’s affiliated institution and the responsible contact at NanoTerasu.

AED (Automated External Defibrillator)

AEDs are installed in the following locations. Please use them for life-saving activities in cases of cardiac arrest.

1. Entrance Hall (2nd Floor)
2. Near Sub-Entrance 1 (1st Floor)
  • ※ Additionally, an AED is installed near the elevator hall entrance in the Storage Ring Building’s Inner Loading Area (1st Floor: Radiation-Controlled Area), primarily for emergency use by NanoTerasu staff.

Response to Minor Injuries and Health Issues

  • In case of injury or health issues, users should seek medical treatment at the nearest healthcare facility at their own discretion.
  • During the Users Office working hours (weekdays 9:00–17:30), users may use the Resting Room for bed rental or receive basic first aid, depending on the situation.

Note:

  • Due to Pharmaceutical and Medical Device Act (PMDA regulations), NanoTerasu does not provide over-the-counter medications (e.g., oral medicine).
  • Over-the-counter medications can cause severe allergic reactions or side effects depending on individual health conditions.
  • Users should bring their own medications after consulting their primary care physician or pharmacist.

  • Do not take the dosimeter outside the NanoTerasu facility. If it is accidentally taken outside and cannot be returned by 17:30 on the same day, contact the Radiation Safety Office at 022-785-9991.

Observing Experiments and Temporary Access to Radiation-Controlled Areas

Non-Radiation Workers must apply for Temporary Access before entering radiation-controlled areas. They must also be escorted and supervised by a Radiation Worker.

Experiment Observation (Entering to Experiment Hall Only)

  • Visitors who do not directly participate in  experiments but wish to enter the Experimental Hall for observation, supervision, preview, discussion, etc.  must have an escort (registered as a Radiation Worker or a Non-Radiation-Controlled Area BL User (Radiation Handler)) submit a visit application to the Experimental Hall via the Radiation Management System.
  • This application does not grant access to the Experimental Hutch.
  • Visitors should refrain from observing beamlines other than those used by their experimental group without permission.

Experiment Observations (Entering Experimental Hutch)

  • If visitors also wish to enter the Experimental Hutch, a Radiation Worker or Non-Radiation-Controlled Area BL User (Radiation Handler) must apply for Temporary Access via the Radiation Management System ( A visit application for the Experimental Hall is not required.).
  • The Users Office will provide one electronic pocket dosimeter (EPD) per tour group. The group representative must wear it at all times and return it to the Users Office after the observation tour.
  • Handled the EPD in the same manner as a Luminess Badge (it does not have a QR code). Additionally, do not place the EPD near mobile phones or smartphones, as strong radio waves may cause malfunctions.  If you suspect that the EPD may have malfunctioned due to radio wave exposure, please inform the Users Office.

When Non-Radiation-Controlled Area BL Users Enter Experimental Hutches to Assist in Experiments

  • Non-Radiation-Controlled Area BL Users (Radiation Handlers) are not permitted to enter the Experimental Hutches without completing the Temporary Access procedure.
  • If a Non-Radiation-Controlled Area BL User needs to enter the Experimental Hutch to assist with an experiment, the experiment leader or co-experimenter (who must be a Radiation Worker) must apply for Temporary Access via the Radiation Management System (at least three days before the experiment.)
    Note: Experimental assistance includes sample exchange, and the transportation, installation, wiring, and adjustment of measuring instruments or sample cells that are not part of radiation generators.
  • The Users Office will provide one DIS dosimeter per experimental group. The experiment leader or their representative must collect it. The collection times and procedures are the same as those for the Luminess badges mentioned above.
  • The DIS dosimeter must be worn at all times by the experiment leader or a co-experimenter who enters the Experimental Hutches.
  • DIS dosimeters should be handled in the same manner as Luminess badges (they do not have a QR code.)
  • After the experiment, return the DIS dosimeter along with the Luminess badges to the collection box at the Users Office.

Precautions When Using the Beamline

Carrying your Certificate of Education and Training Completion

  • Registration as a Radiation Worker or Non-Radiation-Controlled Area BL User (Radiation Handler) is completed by taking the education and training course (e-learning) and passing the comprehension test through the Radiation Management System, etc. Those who pass can print their Certificate of Education and Training Completion from their My Page on the system.
    Note: BL Users affiliated with non-Japanese institutions will receive the certificate from the Radiation Safety Office via e-mail after completing all registration processes and e-learning courses.
  • Experiment leaders and co-experimenters conducting experiments at NanoTerasu must print their Certificate of Education and Training Completion and display it visibly to NanoTerasu staff while in the Experimental Hall. A cardholder for this purpose is available at the Users Office.

How to use the Experimental Hutches

The Experimental Hutches are equipped with interlock systems to prevent radiation exposure to users. However, incorrect usage may not only  interrupt experiments or trigger emergency shutdowns of the accelerators, but, in the worst case, lead to radiation exposure accidents. Ensure a thorough understanding of the education and training content and follow the instructions given by the person in charge of the BL.
To introduce synchrotron radiation into the Experimental Hutch, an exit sequence must be executed to set the hutch to a normally closed state.

  • Before starting the exit sequence, confirm that no one else remains inside the hutch .
  • The person initiating the exit sequence (Radiation Workers only) must be the last to exit the hutch.
  • Ensure that the automatic door of the experimental hutch remains in its normally closed state, before opening the shutter according to the designated procedure.
  • Consult the person in charge of the BL before opening any manual doors or cable ducts. Do not open them when the hutch is in its normally closed state.
  • Do not move fixed shielding materials such as the beam stopper inside the hutch. If adjustments to the movable beam stopper, etc., are needed during hutch switching, consult the person in charge of the BL (users are generally prohibited from moving them).

Chemical Substances

Handling of Chemicals and Reagents

  • Chemical substances and reagents must be handled under the user’s own responsibility. Please share information regarding their hazards, toxicity, and risk assessments within your experimental group, and also provide this information to the NanoTerasu side.
  • When handling chemical substances, users must obtain a Safety Data Sheet (SDS) in advance to understand the properties, hazards, and toxicity of the substance before handling it correctly. The same applies when bringing substances in high-pressure gas cylinders.
  • As a general rule, when using volatile reagents, users must wear appropriate protective gear (gloves, protective clothing, goggles, etc.), and then turn on the fume hood before opening reagent bottles inside the fume hood.

Bringing Chemicals and Reagents into NanoTerasu

Basic Rules

  • When bringing toxic or hazardous substances (e.g., poisons, deleterious substances, organic solvents), please consult with the person in charge of the BL in advance.

Definitions:

  • “Poisons” refer to substances regulated under Article 2 of the Poisonous and Deleterious Substances Control Act and listed in Appendix 1, excluding pharmaceuticals and quasi-drugs.
