| The [[Detectors#Tracking Parallel Plate Avalanche Counters (TPPAC)|TPPACs]], the [[Detectors#Ionization Chamber|Ion Chamber]], and the [[Detectors#Cathode Readout Drift Chambers (CRDC)|CRDCs]] have ISEG power supplies run through a single VME-based bias control. The computer interface for this bias control -- the S800 Detector HV Control -- is typically run on the **devop1** computer in data-U6 and is started by clicking on **S800 HV** under the Operations option on the taskbar. The [[Detectors#Plastic scintillators|Object scintillator]] and the [[Detectors#Plastic scintillators|FP Scintillator]] are each controlled separately as described below under the sections for each detector. | The [[Detectors#Tracking Parallel Plate Avalanche Counters (TPPAC)|TPPACs]], the [[Detectors#Ionization Chamber|Ion Chamber]], and the [[Detectors#Cathode Readout Drift Chambers (CRDC)|CRDCs]] have ISEG power supplies run through a single VME-based bias control.

| The bias for the object scintillator is controlled via the H.V. power supply {{:wiki:Manual_Canberra_HV_3002D.pdf|Canberra model 3002 D}} located in the crate to the right of the data-U6. The voltage will be adjusted at the beginning of the experiment. This scintillator has to be turned off or put on "standby" when entering the vault due to its sensitivity to light. | The bias for the object scintillator is controlled via the H.V. power supply {{:wiki:Manual_Canberra_HV_3002D.pdf|Canberra model 3002 D}} located in the crate to the right of the data-U6.
