FTPC detector operator home page


Please remember to place the FTPC into "Physics" mode and verify anode voltages (1800 W, 1800 E) after taking pedestals.

In case of an FTPC alarm,please check the "Temperature-Pressure" window - if ALL readings in FTPC East and/or West = 0, call Alexei.

In case of an anode trip, please enter the time the trip occurred and which FTPC and sector tripped into the FTPC log book.

Y2004 Standard set points

ALWAYS!!!!!! verify Anode Voltages = voltages for selected run mode !!!
