Power controls, Sept. 2006A.Fabich1 MERIT installation: Controls for the 5MW power-supply A.Fabich CERN AB-ATBSeptember 2006 Power controls, Sept A.Fabich 2 People AB/PO Gilles Le Godec AB/CO Marc Vanden Eynden Pablo Alvarez Sanchez (Javier Serrano) MERIT Adrian Fabich (Ilias Efthymiopoulos) Power controls, Sept A.Fabich 3 Outline Purpose of this meeting Evaluation of possible layout and work effort The 5MW power supply in building 193 Controls layout Estimate of installation work Power controls, Sept A.Fabich 4 Reminder MERIT Single pulse experiment (limited cycles ~500) Runtime very limited (a few weeks) Installation is temporary Jan-July 2007 (Run including a commissioning phase) Solutions and implementation of controls layout could be based on rental. Budget (T273180) available Power controls, Sept A.Fabich 5 Location ISR Westarea MERIT control room Power converter MERIT experiment and local controls (underground) Power controls, Sept A.Fabich 6 Building 193 AD control room AD ring Power controls, Sept A.Fabich 7 Controls layout (Javier) Version 1 (notation Gilles): without GFAS Console MERIT control room (MERIT, AB/CO) G64 (AB/PO) VME (AB/CO) CPU + timing + BC Ethernet Timing (start, stop,...) MIL1553 BC = bus controller Version 1 (notation Gilles): with GFAS CPU Ethernet TimingGFAS BC VME crate (from above) MIL1553 Analogue signal Power controls, Sept A.Fabich 8 Additional information MERIT control room: room 272 S-002 Independent from CCC Information transmitted to PowerControls Reference current Timing, trigger Information read (displayed in MERIT control room): Current reading Status of power supply (Off, ready, interlock, error) Power controls, Sept A.Fabich 9 Questions With or without GFAS? Which parts are already available in building 193? VME crate? Cables (MIL1553, timing...)? Ethernet?... Software in the MERIT control room Where are the interlocks coming into the game? Power controls, Sept A.Fabich 10 Schedule & runtime Spring/Summer 2006: Installation Power supply (converter + transformer) DC cabling (building 193 to TT2A) Autumn 2006: Power converter fully refurbished Winter 2007: AC cabling Controls Commissioning of the power supply February 2007: MERIT hardware installation March-April 2007: MERIT commissioning May 2007: ready for MERIT physics run
