RPC Detector Control System Endcap

This presentation at the Joint RPC/Trigger Meeting outlines the architecture of the Endcap RPC Detector Control System. It covers the Endcap FSM Architecture and details about YEP and YEM disks, 756 RPCs, HV and LV channels, and the overall structure of the system. The presentation also highlights the state machine logic, safe and intermediate states, alarm handling, system initialization, hardware structure, and graphical user interface. The system is nearly ready for a cosmic challenge, but future improvements include temperature monitoring, log files, alarm handling, and condition database integration.

  4. The Final State Machine STANDBY STANDBY STANDBY OFF ON OFF ON Endcap RPC STANDBY OFF ON ERROR • Conformity with Barrel • Disk, Ring and Chamber follow the same logic • Presence of safe states and intermediate states STANDBY Disk RAMP1STEP OFF OFF STANDBY STANDBY Ring ERROR STANDBY Chamber ON RAMP2STEP ON RAMPDOWN OFF Channel ON RAMPUP

  5. Main RPC Endcap DCS panel Ring color adds info on the state Endcap RPC Disk Ring • - Alarm handling • Initialize system • Appearance • Hardware view Chamber Channel

  6. Disk Node Endcap RPC Disk Ring • Objects are cliccable • Global setting Chamber Channel

  7. Ring Node Endcap RPC Disk Ring Chamber Channel

  8. Chamber Node & Channel Panel Endcap RPC Disk Ring Chamber • In conformity with Barrel Channel

  9. Conclusions • Hierarchical structure • Implementation FSM • Graphical interface • Tested with Hardware • Almost ready for cosmic challenge Things to be done • Temperature monitoring (next fw version) • Logfile, Alarm handling and Condition DB • Still testing with final HW config. For CC
