  • If the automatic door does not unlock via facial recognition, please contact the Users’ Office or the Central Facility Monitoring Room 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 will be denied.
  • Any experiment participant (principal investigator or collaborating experimenter) entering NanoTerasu without facial recognition is strictly prohibited.

Entry and Room Access Procedures

  1. First, perform facial recognition using the camera next to the automatic door.
  2. Once identity is confirmed, the blue LED will turn green, and the automatic door will unlock. 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 User of Beamlines Outside the Controlled Area (Handler, etc.).
  • 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 experiment hall is not permitted.

Experiment Observations

  • If an experiment group member (observer) who is NOT registered as a Radiation Worker or a User of Beamlines Outside the Controlled Area (Handler, etc.) wishes to enter the experiment hall for observation, preliminary inspections, participation, or discussions with involved personnel, they must apply for an Experiment Hall Observation Entry Permit. See Experiment Tours (Visiting the Experimental Hall Only) for details.
  • If an observer also needs to enter an experiment hatch, they must apply for a Temporary Controlled Area Entry Permit. See Experiment Tours (Entering Experimental Hutches) for more information.

Safety

Basic Safety Considerations

Compliance with Laws and Regulations

  • When conducting work at NanoTerasu, all users must comply with laws 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. Human Life First
    The highest priority is the safety and well-being of individuals.
  2. Reporting
    Inform those nearby about the emergency and follow the designated emergency reporting procedures.
  3. Preventing Further Damage
    After ensuring your own safety, take appropriate initial actions to prevent the situation from worsening.

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.
    • (Example: During baking procedures while wearing short sleeves, there is a risk of burns if your arm touches a hot surface.)
  • 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 areas inside the Experimental Hall of the Storage Ring Building and the Linac Building, including above the accelerator tunnel.
  • The Experimental Hall is not a radiation-controlled area, except for the interior of beamline hatches.
    • However, if radiation levels are expected to increase due to adjustments to the accelerator or beamlines, safety zones may be set up using barricade ropes.
    • Only authorized NanoTerasu radiation workers are permitted to enter radiation-controlled or restricted areas.
  • 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.)

Emergency Response

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.
    After calling 119, report the ambulance dispatch to the Central Facility Monitoring Room at 022-721-5180.
  • (2) In Case of Fire or Other Emergencies
    If a fire or other emergency occurs, immediately call the Central Facility Monitoring Room at 022-721-5180 (The Monitoring Room 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 d to do so.
    • ※ After reporting to the fire department or the Central Facility Monitoring Room, if possible, notify the beamline staff 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 entrance
    • Parking lots in front of each sub-entrance
    • Roads around each emergency exit

Personnel Accountability

  • The Principal Investigator (PI) must be able to communicate with collaborating experimenters, the Users’ Office, and beamline staff at all times during their NanoTerasu usage period.
    • ※ In the event of a large-scale disaster or fire, the PI 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.

If you feel a strong tremor, follow these steps:

Key Points:

  • NanoTerasu is designed to withstand earthquakes as strong as the Great East Japan Earthquake (2011).
  • Remaining inside the facility is generally the safest option.

During an Earthquake:

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

Radiation Accident Response

If any of the following radiation-related incidents occur, immediately contact the Central Facility Monitoring Room 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 (e.g., unauthorized entry into restricted areas such as the accelerator tunnel or beamline hatches).

Chemical Accidents Response

  • Before bringing chemicals or reagents into NanoTerasu,
    • Review their Safety Data Sheets (SDS)
    • Ensure you understand their properties
    • Prepare emergency supplies in case of accidental exposure or injury.
  • If an incident occurs, follow the same emergency contact procedures as for medical emergencies.

Note:
Emergency showers are located near the Central Control Room in the Experiment 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
21%Normal air composition
18%Safety limit, but requires continuous ventilation
16%Headache, nausea
12%Dizziness, muscle weakness
8%Loss of consciousness, death within 7–8 minutes
6%Immediate coma, respiratory failure, death
  • If You Discover an Oxygen Deficiency Victim:
    • Call for help loudly.
    • Rescue the person only if it is safe, taking care not to become a victim yourself.
      • Hold your breath if necessary and drag the victim out of the room.
      • Follow the same emergency reporting procedures as for medical emergencies.
  • 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 experiment hatches or surrounding rooms.

Other Important Notes

  1. Severe burns (larger than the palm), heavy bleeding, fractures, loss of consciousness, breathing difficulties, or cardiac arrest require immediate medical attention.
  2. If you sustain a head injury, seek medical evaluation regardless of visible wounds or symptoms.
  3. If emergency transport is required, an experiment colleague should accompany the injured person and coordinate with their affiliated institution and NanoTerasu staff.

  • Avoid subjecting the dosimeter to impacts.
  • Secure the dosimeter by clipping it to your chest pocket or a similar location to prevent it from falling.
  • Keep the dosimeter dry, do not expose it to water.
  • 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 Tours (Visiting the Experimental 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) 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 Tours (Entering Experimental Hutches)

  • If visitors also wish to enter the Experimental Hutch, a Radiation Worker or Non-Radiation-Controlled Area BL User 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 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.)

Precautions When Using the Beamline

Carrying your Certificate of Education and Training Completion

  • Registration as a Radiation Worker or 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.
  • 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

  • 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.
