1 MDT PS DCS for ATLAS Eleni Mountricha
National Technical University of Athens Power Supplies DCS group Eleni Mountricha NTUA

2 Outline MDT chambers in ATLAS and their HW PS DCS system
Present Status of PS system Conclusion Eleni Mountricha NTUA

3 MDT chambers in ATLAS and their Hardware
Eleni Mountricha NTUA

4 ATLAS experiment and MDT chambers
MDTs Side A Side C Endcaps Barrel Inner Middle Outer stations 16 sectors 1150 chambers Eleni Mountricha NTUA

5 and the naming convention
MDT chambers and the naming convention BIL1A01 B I L A 01 partition layer size station side sector Eleni Mountricha NTUA

6 Power Supplies modules
Mainframe CAEN SY1527 Branch Controllers A1676 Crates Boards LV: A3025 & A3016 HV: A3540P Eleni Mountricha NTUA

7 PS DCS system Eleni Mountricha NTUA

8 Software DCS PVSS (SCADA system) and Finite State Machine (SMI++ tool)
User Interface Layer Processing Layer Driver Layer CTRL API EV D UIM DM Communication and Memory Layer Monitor and control Hardware using PVSS elements (datapoints) Automate system in propagating commands as well as state and status Commands States & Alarms DCS Tracker Vertex Muon Gas LV HV Cooling Eleni Mountricha NTUA

9 PVSS datapoints Datapoints that correspond to hardware modules (channels, boards, crates, branch controllers, mainframe) Datapoints that correspond to the chambers Internal datapoints for the FSM for the OPC Server (communication with hardware) for the RDB manager (archiving of datapoint elements) Alarms are activated for the datapoints and their elements Eleni Mountricha NTUA

10 FSM trees One FSM tree is implemented for each partition
Hierarchy is set for the parts of the system (nodes and their children) Commands and states propagate correctly Eleni Mountricha NTUA

11 FSM panels Eleni Mountricha NTUA

12 Tool panels Panels used by experts for the configuration of the system : alarmHandling.pnl communicationHandling.pnl archiveHandling.pnl fsmHandling.pnl chamberDpHandling.pnl settingsHandling.pnl descriptionHandling.pnl Eleni Mountricha NTUA

13 Tool panel example Eleni Mountricha NTUA

14 Present status of PS system
Eleni Mountricha NTUA

15 Barrel Most chambers are incorporated in the system having LV modules (9 modules missing) HV modules for almost all chambers in sectors 1-12 Eleni Mountricha NTUA

16 Endcaps Both Big Wheels and Small Wheels (one for each side) are incorporated to the system having both LV and HV modules Chambers in the Outer layer in side C are also incorporated in the system but most LV modules are missing Eleni Mountricha NTUA

17 Conclusion Eleni Mountricha NTUA

18 PS DCS system is in use for the MDTs
Improvements are made in the PVSS/FSM part of the system to achieve higher stability of the system Development is implemented concerning expert panels to achieve more efficient control of the system MDT PS from the HV/LV modules’ point of view are reaching their completion Eleni Mountricha NTUA
