Getting things ready to start at NL23 tomorrow morning. If everything goes smoothly I will get to NL24 in the afternoon.
3 to 4 power supplies will be turned off and HV cables locked out at a time per zone until the whole zone is done.
Beamline pumps (A & B) will not be effected since they already have HV jumpers and black boxes.

Readbacks for these pumps and insulating vacuum gauges will be interrupted during this work.
Spoke with Frank about loosing readbacks and pumps being turned off.
