3 June 2003U. Frankenfeld2 TPC sub-detectors and sub-systems TPC ROCField cageTh. ScreenLaser High Voltage Low Voltage High Voltage Cooling I monitor Cooling Laser Alignment FEE Cooling Pulser Gas Sys. Drift URD Prototype Production

3 June 2003U. Frankenfeld3 ROC Low Voltage Wiener PL 500 –5 channel/crate –1 - 2 channels per voltage for FEE Prototype used for tests –OPC from IT/CO Interface: Wiener OPC still beta version (delay ~1.5 y) Hardware limitation: –No indication of status (mainly needed for prototype and test, no access in Alice) –No individual switching –Setting voltages only if crate is off

3 June 2003U. Frankenfeld4 ROC High Voltage ISEG Prototype for tests Interface: OPC beta release (with problems) Final (and last) in June (working to specs?) –Final version: no individual switching on/off per channel Limitation of proto OPC (temporary solution) –No individual switching of channels –Not nice (but ok?) –No Hardware limitation (ref. to user manual)

3 June 2003U. Frankenfeld5 ROC Cooling Wago μPLC Prototype tested –Ok –Not radiation hard –Study of thermal behavior of ROC/FEE 2 nd Prototype: –ELMB solution –Under test/development at thermal Lab (CERN) –Set point for cooling plant Highest requirements on temperature stability –Prototype for all systems

3 June 2003U. Frankenfeld6 TPC-FEE DCS -> Ralf Ethernet switches in the Magnet? –Otherwise 216 cables

3 June 2003U. Frankenfeld7 Pulser URD available Development has started

3 June 2003U. Frankenfeld8 Field cage High Voltage –Offers for Power supply –Interface to SCADA system I monitor –Design of circuit started –Interface to SCADA system

3 June 2003U. Frankenfeld9 Laser No URD (on the way) Discussions started Items: –Control of the two Lasers –Mechanical control –Control of camera

3 June 2003U. Frankenfeld10 Gas system System is build (almost ready) Control by gas working group Link to DCS to be defined –Reading of status –Reading of temperatures –…. –Only reading, no control Additional Sensors –Drift Monitor –Pressure

3 June 2003U. Frankenfeld11 Controls Hierarchy To Devices (HW or SW) Action Status & Alarms ECS DCS TPC TRD FCROC Crat e LHC... Device Units Control Units Abstract levels... HV Cool.LV Crat e DAQHLT...

3 June 2003U. Frankenfeld12 Controls Hierarchy Start simple for CERN test LV an HV connection to devices –Prototype OPC with limited functionality Complexity growing with time –Integration of additional subsystems Final system: –Number of FSM? –Grouping? –Discussion with HMPID

3 June 2003U. Frankenfeld13 Miscellaneous Power for ELMBs (Switches, RCU DCS board?) What Sensors when and where? –Archiving Temperature sensors Additional Sensors –Pressure –???

3 June 2003U. Frankenfeld14 Summary Prototypes HV, LV & Cooling by Sorina Status –Prototypes will be used in sector test –URDs –Laser URD on the way Limitations: ISEG (OPC) and Wiener (Hardware + OPC) Cooling and Gas system: Hans
