Detector Operation
FTPC expert(s) currently on call:
Alexei Lebedev alebedev@bnl.gov Phone: 3101 Cell phone: 631 255 4977
TO ALL DETECTOR OPERATORS:
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
- Detector always ON
Change configuration to operate in different modes or to set the detector to rest waiting for beam
Set the system in ``Magnet ramp'' configuration ONLY when the magnet is ramping
ALWAYS!!!!!! verify Anode Voltages = voltages for selected run mode !!!
