Beamline Operation

All users must strictly comply with the safety regulations and operational procedures of the Synchrotron Light Research Institute (SLRI). Operation of Beamline 2.2 (BL2.2) is permitted only for trained and authorized personnel.

• Only users who have received authorization from the beamline scientist or safety officer are allowed to operate the beamline. The user must sign the SOP form before performing experiments at BL2.2.
• Users must wear the provided OSL radiation badges (Optically Stimulated Luminescence dosimeters) at all times within the experimental hall.
• Entry to the experimental area is strictly prohibited during beam injection or operation.
• Any malfunction or abnormal condition related to radiation safety must be reported immediately to the beamline staff.
• Food and beverages are not permitted inside the beamline station.
• Users must maintain a clean and organized work area throughout the experiment.
• At the conclusion of beamtime, all personal materials and samples must be removed, and the beamline area must be cleaned and restored to its original condition.

PSI System protects workers from immediate radiation by preventing them from accessing beam enclosures and other locations where there is a risk of high radiation exposure. It consists of mechanical barriers and locks as well as electronic interlocks. The interlocks also serve to turn off the radiation source if any of the interlocked barriers entering the beam enclosures are broken.
