Hi Don,

Thanks for the response. Can you tell me how you are tracking the charge, is there a sensor recording this or is this provided by MCC?

Hi Marc,
We recorded around 56 coulombs of charge in the hall since it was installed.

Hi Don and Mark,

Can anyone provide information on how much "beam-time" the test stand has received? I know it was moved to the hall on 9/1, but I am not sure when you had beam in the hall. Additionally, beam is intermittent, so maybe there is a counter of total beam into the hall.
