1 Developing on HV/LV power supply system for RPC 1

2 Requirements and system description wheel TOT gaps front-end HV ch. 960 LV ch to save money but to preserve trigger we chose: 1 HV channel per 2 gaps (3 gaps for RB2ref) 2 LV channel (Analog + Digital) per 6 FEBs (96 strips) 2

The remote crates having 21 slots, will host per quadrant: one Control Board (1 slot), 6 LVBs ( slots); one Control Board, 3 HVBs (9 slots) and 3 LVLB (6 slots); 7

11 RPC Power supply system RPC Power supply system: requirements and system description II For maintenance reason, we could: use Off-The-Shelf modules (6HV chans floating/module) in Control Room (USC55) (~200 mt far away from detector); develop LV custom module, having floating channels, organized as x3 groups; develop remote controller for the LV modules use of SY1527 system crate in Control room for: controlling and housing the necessary OTS modules remotely controlling the LV custom modules use the custom crate, commonly developed for all CMS, for housing of the LV modules placed on balcony, in dedicated racks. 11
