UITF Internal Safety Review – Personnel Safety
List of Hazards
Gun System:
- High Voltage (350 KV)
- Pressure Vessel containing SF6 (60 PSI)
- SF6
Laser System:
- Class 4 laser at 780 and 1560 nm
Vacuum Systems:
- Pumps (Is there a need for hearing protection?)
- Beam line terminations (flanges capped off?)
Electrical and Magnets Systems
- Ion pumps
- Magnet terminals
- Magnetic fields
Cryogenic fluids
- Liquid Helium to ¼ cryomodule
- 500 L and 1000 L liquid Helium for HDIce
- Nitrogen gas line
Non-ionizing Radiation
- Warm RF (Buncher and Chopper systems)
- High Power RF to ¼ cryomodule
Define operational modes
- Low energy operations (restricted to Cave 1, beam current 32 mA, beam energy <250KV, or 3mA at <400kV)
- High energy operations (for HD-Ice, beam current , < 100nA, PSS BCMs)
- Maintenance, no beam
Ionizing Radiation
- Due to beam during UITF operation, or field emission from ¼ CM and gun
- Residual radiation after turning off the beam
Access Controls
- Levels of Access (Restricted/Beam Permit)
- Sweep procedures (prior to beam operations)
- Access control procedures post-beam operations
- CARMs
- BCMs (<100 nA into Cave 2)
Signage
- ODH posting
- HV
- Laser
- Magnetic fields (if higher than 5 G, about 1 ft from the magnet)
- Beacons, if needed (maybe at the gate when beam in UITF)
- Beacons above the cave (restrict access when RF/Beam on)
