22:11 After graphing the ToT from runs 522-530, noticed that it was not changing as much as expected, leading us to believe that maybe remotely changing the HV might not be working. To check, we set the voltage to 0 and took data but did not see what we expected. The camera pointed at the equipment rack didn't have the HV PS in the frame so we requested an access to go down and see whether remotely chaning the HV actually works or not. We confirmed that the HV was changing but the script must have an indexing error on its for loop because whenever the HV is set, it always ends up at a value 1 off from what was set. For example if we were at 20V and set it to 15 we would end at 16 and if we were at 10 and set to 15 we would end up at 14. After figuring out that the voltage was changing but not to where we expected, a new webcam was moved to have the HV panel in views o view so it could be monitored.
22:52 Beam restored and Run 534 started.
22:03 MC called to take away beam after Run 534 was completed.
