Presentation Transcript

  1. Deutsches Elektronen Synchrotron Hamburg PVSS inside the DESY H1 experiment An overview by Sven Karstensen, DESY Sven Karstensen, DESY Hamburg

  2. DESYgeneral overview International Collaboration: 2900 scientists from 33 nations are using DESY facilities Staff:employed at DESY Hamburg in total 1390, therefrom 300 scientists User of DESY-facilities: particle physics: 1000 scientists from 25 countries HASYLAB: 1900 scientists from 31 countries Sven Karstensen, DESY Hamburg

  3. DESYfacility overview HERA: Hadron-Elektron-Ring-Anlage (Facility) build: 1984 – 1990 costs: 700 Mio. € participants: 11 countries dimension: 6.3 km long ring accelerator energy of electrons: 27,5 GeV energy of protons: 920 GeV 3(4) experiments: H1, ZEUS, HERMES, (HERA-B until 2003) and: TTF Tesla Test Facility HASYLAB Hamburger Synchrotron Laboratory Sven Karstensen, DESY Hamburg

  4. The H1 Experiment • working since 1992 • universal detector • 12 m x 10 m x 15 m • 2800 Tons • 380 collaboration members • finding the inner structure of protons • extending the knowledge of the fundamental strengths • searching of new material forms • quests for new unsuspected phenomenons inside the particle physics Sven Karstensen, DESY Hamburg

  5. Problems in the past(why a new control system ?) • computers getting old • 1 to 1 connection • interconnection via FTP • no direct data base connection • remote control via Timbuktu / VNC • many different GUIs • every detector needed his own expert • huge amount of manpower Sven Karstensen, DESY Hamburg

  6. less manpower than before short initial training redundancy alarm handling archiving standard driver OOP, C++ API, OPC graphical surface (as Labview) Running on LINUX and NT Slow Control System High Voltage control Solenoid-Current / Vacuum / Cryogenic control Stepping Motor control ORACLE connection (Info server) SMS messaging system for experts HTTP / WAP interface floating change was possible Finite State Machine (CERN) PVSS as a solution Sven Karstensen, DESY Hamburg

  7. PVSS technical data Sven Karstensen, DESY Hamburg

  8. PVSS structure in H1 … and many more … Sven Karstensen, DESY Hamburg

  9. Future acceleratorsXFEL and ILC 32 km ILC XFEL New projects, where DESY is involved: XFEL (X-Free Electron Laser) and ILC (International Linear Collider) Sven Karstensen, DESY Hamburg

  10. … the end Thank you very much Any questions ? Sven Karstensen, DESY Hamburg
