Follow-up Re: VTPAD00A done
An access to the Hall D tagger was made to inspect turbo shutting off and spooling down. The turbo power switch was power cycled off and then turned back on. The turbo cart restarted and spooled up without issue. This problem has happened in the past and described as a bit flip that causes the unit to power down and will usually power back up upon restart. The plan is to relocate the affected controller during the SAM. We will leave the Beam-line valves closed for now and continue pumping. Pressure is in the mid 6 range.

Notes:
1. Hall B current is 5 nA and not 5 uA - see Figures 1-2.
2. In the summary of results, the values of the currents are not right. For example, Hall C current is 65 uA but it is listed as 52 uA. See Figure 3 compared to Figure 1.
3. Hall C results are clearly not right.
