  1. Status of the preparation for KEK test beam M. Yoshida (Osaka Univ.) MICE VC 2005/9/14

  2. VLPC Cryostat delivered to KEK • Cryostat and the other equipments delivered to KEK on Aug. 24th • Commissioning started by Alan and Japanese guys • Succeed to reach 6K • Stable operation in 3 weeks

  3. KEK-PS p2 exp. area USHIWAKA spectrometer magnet VLPC Cryostat Tracker prototype inside

  4. Beside p2 area Cryostat over the fence DAQ electronics Compressor for Cryocooler He gas ctrl to Cryostat Power Supply to AFE Linux/Windows PCs

  5. Cryostat LID heateragainst condensation • Typhoon approaches to Japan in Aug. and Sept. • High room temp. and high humidity • Condensation on LID of Cryostat! • Need to keep the LID temperature higher 65.0F@FNAL 86.5F@KEK

  6. Electronics Linux/Windows PC VLSB TDC ADC MIL-1553 SASEQ Interrupt Register AFEII (Cryostat Backplane) Slow Ctrl CLK/TRG LVDS data links Bit3 interface

  7. DAQ/CTRL program on Windows PC • VB macro programs on Excel • Check AFE functionality for each • Initialization • Diagnostics • Data aquisition

  8. Pedestal distribution AFE#104 AFE#105 AFE#106 ADC counts AFE#107 channel number

  9. DAQ software on Linux PC(UNIDAQ)

  10. Status / Schedule • TOF hodoscope, Aerogel Cherenkov counter, defining counter and other beam counters are ready. • Cryostat works quite stably. • Electronics has been delivered. (although not for all channels of VLPC) • Improving DAQ with VLSB and VME ADCs/TDCs. • Continue preparation work by 4 or more Japanese colleagues • 5 from US, 4 from EU will join around Sept. 28. • 2 from UK will join Sept. 20 to install tracker into solenoid magnet. • Sept. 20 : Remove USHIWAKA magnet and cleanup p2 area • Sept. 21 • Set the solenoid magnet • Install the tracker • Install beam counters. • Sept. 27 : Accelerator tuning will be started • Sept. 28 : VLPC fully commissioning by experts from FNAL • Sept. 29 : hopefully internal target ON, and beam could be provided to p2 although it is unstable • Tuning beam counters. Trigger setup. • Oct. 3 – Oct. 7 : Stable beam.
