Reminder. Mini pump still linked to SV1. DO NOT OPEN SV2!!!
The plan for today Wednesday, July 01, 2020 (  ) is:
- Coil sweep with gas lines opened.
- Coil sweep with gas lines closed
- Coil sweep with gas lines opened.
- Efficiency measurements at highest and lowest FC6 signal
- Mass scan.
COVID-19 protocol: buddy is Marla Cervantes

Wednesday, July 01, 2020, 11:50: FC6=6.89e-12A. IG1=2.76e-6T.
FC6 has dropped 60% and the vacuum 15% with the respect to the last set of measurements.
Maybe the mass is not Ar+ but K? Or the decrease in pressure has this large correlation to FC6 magnitude.
Wednesday, July 01, 2020, 12:41: Coil sweep up and down completed.
Wednesday, July 01, 2020, 12:47: SV3, SV4, and SV5 close
IG1=2.59e-6T. The gas bottles are definitely running out, as there is no much change in pressure whether they are opened or closed
Wednesday, July 01, 2020, 13:15: Coil sweep completed.
Wednesday, July 01, 2020, 13:22: FC6 and IG1 increasing. Probably due to the coil still at 90A. reducing coil current.
Wednesday, July 01, 2020, 13:29: SV1 open. SV3 open/closed x5. SV4 open/closed x5.
Wednesday, July 01, 2020, 13:31: SV3 and SV4 open.

Friday, July 03, 2020, 12:41: EPICS restarted but still whiteout problem similar to e-log 702. Likely to submit a faulty report
Friday, July 03, 2020, 12:57: PLC restarted, EPICS workings.
Friday, July 03, 2020, 12:58: Turbos at speed.
