Dosimetry reading completed by Adam Hartberger. See attached summary file. These optichromic dosimeters max out at ~20 kGy = 2 Mrad. Eight of the twenty locations monitored appeared to have exceeded this dose during the final 5 weeks of Physics ops in 2020.
Tesla coil test completed. Streamer arcs as well as HV discharges into the ground adjacent to 70 MHz distribution system in W1 did not trigger PLL error in the LLRF systems (SL, W1, W2).
For the next step we are planning to use electric welding machine ( DC one) in W1 ( there is no plan to compromise the construction integrity of the building). I have asked Neil Wilson for help.
MFG technician will be onsite January 6th and 7th to perform initial starter checks and startup. Technician will verify installation and perform a bump test on the starters to check rotation on compressor motors.
The CHL1 transformers will need to be energized to warm up before the technician arrives (Energized at the beginning of the week). Lockout devices currently on the CHL1 SWGR will need to be removed if no longer applicable to work.
Calibrations on the high voltage divider boxes in zones 0L02, 0L03, and 0L04 were completed. Also, calibrations of both the digital and analog read backs for both the voltage and current on zone 0L02 were completed, as well as the current trip point calibration. Further troubleshooting is required to complete calibrations for digital read backs on both the voltage and current on zone 0L03.
