Trigger  Monitoring Checklist L3

High Voltage To TRIGGER counters Look at HV_Control.vi on the Plastic computer.

Scalers

Record the visual scalers in the chart below.  Do not stop the scalers to make the measurements (make estimates where necessary).  Do not reset the scalers.

Scalers are reset only at 10 am.  Each morning at 10 am, the shift crew should reset the scalers and record the reset time in the online logbook.

Please write any comments you feel pertinent ('start of run', 'middle of long store', 'beams steered in our area', etc.)
