The Alice-ToF HV system and the PVSS control system
E. Scapparone for the Alice-Tof group
DCS Workshop, June 16
- The ToF High Voltage layout ;
- Component selection and adopted solutions;
- PVSS work started !
- 18 sectors ( 20o tilted )- 5 modules/sector- from 15 to 20 strips/sector- HV ranges +(-)7.5 kV ( but the system can hold up to 15 kV).

A prototype of the Kerpen cable equipped with these 3-polar connectors ready, just tested.
-The HV Control PVSS based just started , taking advantageof the HMPID group help.
-At the moment, PVSS Version 2.12 + Framework 1.2, running on W2000.
- First choice of the Detector view
