- | The TPPACs, the Ion Chamber, and the 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 Object scintillator and the FP Scintillator are each controlled separately as described below under the sections for each detector. | + | The [[Detectors# |

- | The bias for the object scintillator is controlled via the Canberra HV supply located in the left rack in Data-U6 in the NIM bin just underneath | + | The bias for the object scintillator is controlled via the H.V. power supply |

The bias of each of the two detectors, PPAC1 and PPAC2 is controlled individually via the S800 Detector HV Control. There are two types of detectors used for the TPPACs: either the “classic” PPACs or PPACs with individual strip readouts for handling higher rates. There is not a difference between the two detector types in terms of how the data is used. They do differ in terms of electronics and acquisition. | The bias of each of the two detectors, PPAC1 and PPAC2 is controlled individually via the S800 Detector HV Control.
