  1. CYRIC Hyperball2 infrastructure インフラ整備

  2. Preparations • Electric power supply • Cabling • FERA and Double buffer • Ge check by Takeshi Yamamoto • Beam line alignment by Takeshi Koike

  3. Power supply • 4 power lines (A,B,C,D). • Each line has 15 A current limit. • A and B, C and D are combined (30 A limit). • A : All NIM-BINs (11 A w/o 671 and signal) • B : CAMAC1, VME1 (9 A w/o signal) • C : CAMAC2, VME2 (9 A w/o signal) • D : All FANs, BGO HV, PC (9 A BGO off) • For Siball and BGO multi-filer, we will use another power line “E” which has 50 A limit.

  4. Cabling • TFA→CFD→TUL→FI/FO→TDC or trigger • All re-cabling and check connections • CFD decay cable • 20 ns or 18 ns cable delay + variable delay • CFD reset veto line • Trigger part (ADC gate and so on)

  5. FERA and double buffer • FERA system works well. • Signal timing and number of data are OK. • Expected dead time ~28 ms (average) • FERA data bus cable has some trouble… • 4~7 bit all “1” (under 8 bits are always “fX). • I lose 18 of 34 pin connecters… (´д｀;) こんなチョンボがあるなんて～

  6. TO DO • FERA and double buffer • Analyzer • DAQ Module check (all channels) • Other preparations →M2, M1, M0 • Number of TFA is not enough. • 33 TFA (36 needed) are available because of noisy TFA.

  7. To be loaned from RIKEN • 671, TFA • Preamp power supply • NIM module and NIM-BIN • NIM-BIN for Siball and BGO filter

  10. Long run monitor test (at Seiko ) • 10/15~ • 10/25 C/H 61.3K, Ge 77.3K (Pre.Amp. OFF) • HBJ det. No.1 test • Det. No.1 delivery to Seiko ~10/31 • Resolution measurement at(10/26) ORTEC • Performance test with LN2 • Chamber production (Fuji elec.) • Assembly and pumping @ Seiko (2~3 days) • Start of cooling and test run • Cooling profile • Resolution measurements • Canberra dummy cooling test • Connection design in progress?
