  1. CCEB QM/FMProduction StatusTIM CERN May.09 Gert Viertel, Ulf Roeser, Andreas Sabellek IEKP - Universität Karlsruhe (TH)

  2. Cryocooler Electronics System Overview 4 Cryocoolers Zenith Radiators PT1000 Temperature sensors HEAT 120 VDC in 4 x VAC out from PDS CCEB Dallas temperature sensors JMDC CAN Bus Cernox Cryogenic temperature sensors USCM task program by A.Lebedev autonomously regulates power to Cryocoolers 3D Hall probes TIM May09, CERN

  3. Cryocooler Electronics Box Universal Slow Control Module USCM CCEB Crates EM1: ETHZ EM2: CERN (for CC operation) QM: in prod. FM: in prod. USCM 3D Hall Probe and PTS readout CCBT 0 CCBT 1 CCIF 0 A/B CCIF 1 A/B Interface Board CCIF 2 A/B CCIF 3 A/B Control Side Monitor & Oscillator CCMO 0 CCMO 1 CCPA 0 A/B CryoCooler Power Amplifier Module CCPA 1 A/B Power Side CCPA 2 A/B CCPA 3 A/B DC/DC Converter board CCDC A/B 3 TIM May09, CERN

  4. FM/QM Board Status • Status: All boards were assembled and delivered by Contraves company Zürich by April, 30th • Currently last board level test are performed at ETH Zürich and final coating/assembly is prepared CCEB Crate ready for assembly (from CSIST) TIM May09, CERN

  5. CCPA Board Level Test • quantity: • 4 FM, 2 FS, 4 QM • before coating: • check of output voltage puls shape • load test • - adjustment of HW current limit (max power 150W/CC @126V) • calibration of voltage*current readout • relais check (launch lock) • full functional test 10 x CCPA boards before final mechanical assembly • all failures could be repaired and defective parts were replaced TIM May09, CERN

  6. Production Schedule Dates QM&FM: May 25 – June 5 CCEB Crate Assembly (CERN) June 8 – July 3 CCEB ESS/TVT at SERMS (Terni) (U. Roeser / A. Sabellek / J. Schneider / [M. Droege]) by G. Viertel TIM May09, CERN

  7. Summary • all CCEB boards are delivered and show no major problem; last boards on the way for final coating • CCEB 1 x QM and 1 x FM assembly end May • preparation for ESS and TVT qualification/acceptance test at SERMS in Terni in June board level testing at ETH Zürich TIM May09, CERN
