  1. ALICE TOF DCS Workshop 6-7 October 2005 O. Pinazza and F. Cindolo for the TOF group

  2. TOF DCS status report • TOF HV subsystem • TOF LV subsystem • FEE control planning • FSM and integration • Plans • Answers: • TOF inventory • TOF overview drawing

  3. TOF HV hardware

  4. TOF HV controls • standard: PVSS + framework + OPC • just an alternative data archive (fprintf) and customized user panels

  5. TOF HV status • the system is on since 2003 with some improvements • at present a test for cosmics is running at CERN and the monitor and control system are working well • the system is very light: 12 channels • but is running for months on a low performance laptop in the public Cern network

  6. TOF LV hardware

  7. TOF LV: the CAEN ALICE-box • CAEN custom device, derived from an EASY crate

  8. TOF LV: Alice-box

  9. TOF LV: Alice-box • TOF has tested the thermal performance of the water cooled case in magnetic field simulating a full load

  10. TOF LV: Alice-box • TOF has tested the LV connections and controls in the “almost” final position at Point2

  11. TOF LV controls • at the moment the Framework does not include datapoints for the TOF crate, but JCOP is working on it • TOF has programmed its crate and channels in PVSS • the panels are plain and not yet optimized

  12. TOF FEE • the Front-End components are being delivered in this period and will be tested in our lab • the controls will be programmed after the tests; we will use a linux PC (with the PCI board for the VME crate) with a DIM server and another PC with the PVSS project

  13. TOF FSM and the integration TOF is made of 18 azimouthal sectors (supermodules) HV partition = 1 module one sector is made of 5 modules LV partition = 1 quarter of a sector one sector is made of 4 quarters

  14. TOF FSM TOFinternal ECS requirement

  15. TOF FSM prototype

  16. TOF DCS plans • revision of the LV subsystem using Framework • begin the FEE subsystem with DIM • continue the FSM schema in strict agreement with ECS • test the ROOT-PVSS interface (?)

  17. TOF inventory
