UITF Meeting - May 10, 2016

UITF Internal Safety Review – Personnel Safety

List of Hazards

Gun System: 1. High Voltage (350 KV) 2. Pressure Vessel containing SF6 ( xx PSI) 3. SF6

Laser System: 1. Class xx laser at xxx nm

Vacuum Systems: 1. Pumps (Is there a need for hearing protection) 2. Beam line terminations (flanges capped off?)

Electrical and Magnets Systems 1. Ion pumps 2. Magnet terminals 3. Magnetic fields

Cryogenic fluids 1. Liquid Helium to ¼ cryomodule 2. 500 L and 1000 L liquid Helium for HD-ice 3. Nitrogen gas line

Non-ionizing Radiation 1. Warm RF (Buncher and Chopper systems) 2. High Power RF to ¼ cryomodule

Define operational modes 1. Low energy operations (restricted to Cave 1, beam current 10 mA, beam energy <350KV) 2. High energy operations (for HD-Ice, beam current , <1 μA, BCMs) 3. Maintenance, no beam

Ionizing Radiation 1. Due to beam during UITF operation 2. Residual radiation after turning off the beam

Access Controls 1. Levels of Access (Restricted/Beam Permit) 2. Sweep procedures (prior to beam operations) 3. Access control procedures post-beam operations 4. CARMs 5. BCMs (<1 microA into Cave 2)

Signage 1. ODH posting 2. HV 3. Laser 4. Magnetic fields (if higher than 5 g, about 1 ft from the magnet) 5. Beacons, if needed (May be at the gate when beam in UITF) 6. Beacons above the cave (restrict access when RF/Beam on)
