  1. Latest Developments on the Embedded Assembly System Power Supply for LHC Experiments Giovanni GRIECO CAEN SpAg.grieco@caen.it 9th Topical Seminar on Innovative Particle and Radiation Detectors23 - 26 May 2004   Siena, Italy

  2. Summary • Background / previous CAEN HV/LV activities • Birth of the EASY System • EASY specifications • EASY modules • EASY integration in DCS Latest Developments on the EASY Power Supply for LHC Experiments

  3. Background • CAEN’s Power Supplies R&D activities in the last 8 years: • SY1527/2527 family • OPC Server for the SY1527/2527 • SASY2000 for Radiation Tolerant and Magnetic Field solutions  tested working devices up to: • 7 kGauss • 1*1011 p/cm2 TD - 15 kRadTID • 2*1012 n/cm2 TD • Result: • existence of a series of building blocks for a new power supply concept Latest Developments on the EASY Power Supply for LHC Experiments

  4. EASY 3000/4000 First COTS rad-tolerance tests (ENEA - La Casaccia) SASY 2002 (CMS Tracker PS Proto)tested in Magnetic field in CERN SASY 2002 (CMS Tracker PS Proto) tested under Radiation in LLN Tests with p and n in Louvain-la-Neuve of A877( CMS Muon Chambers) SASY 2000tested in Magnetic field in CERN Start of Special material research SASY 2000 tested under Radiation in LLN New design (Patented) for a family of High and Low voltage DC/DC converters First SASY 2000 functional prototype Today Feb ‘97 Sept 02 Aug 02 May ‘99 May 03 Apr 00 Jul 03 Nov 01 May 02 Hostile Area Experience Milestones Latest Developments on the EASY Power Supply for LHC Experiments

  5. Why the EASY ? • The LHC experiments need common solutions: • Reduce R&D costs (Hardware & Software) • Reduce Hardware/Software proliferation: • Use of the same crates for all Sub-detectors • Use of the same modules where possible • Use of a Common Control System • Reduce Maintenance costs: • Use of Common spare units • CAEN proposes a “catalog” approach with a limited set of modules Latest Developments on the EASY Power Supply for LHC Experiments
