  1. pawel de barbaro Sx5hcal status, plans June 8, 2006

  2. 1. water cooling • hb is completed • he is completed • ho: hooked up, need to turn on YB+2 • need to hook up yb0 and yb1 to HB system, • we will use HB+ sectors 12 and 13 when boxes are installed

  3. 2. N2 inertion • install reducers on HB • he: hookup between wall and manifold, install reducers • ho: yb1 and yb0 needs special solution • need to verify pressure of N2 in sx5 (andre lyonnet)

  4. 3. high voltage • hb done, all the way to gb • he: cables from green barrack to splice box need to be installed • HO: also at the end going thru splice box, until magnet close, it goes thru independent p. supply

  5. 4. dcs • HB+ dcs testeed on thursday afternoon • need to connect HE+ to dcs computer in gb

  6. LV on HBmtcc turned on

  7. 5. low voltage-hardware • still short of one 3016 and one 3486 (we will temporarily borrowed one 3016 from HE+/near to HB+) • all five racks need to be air-cooled, two HE racks are already Ok, other 3 need to be closed • we will pull 48V power cable straight from bb to YB+2 • still to bring cables from p. panel on the wall to easy crate

  8. 6. low-voltage-pvss • first version exists, german preparing upgrade • there is no framework for 3486. • delay swap to central dcs, until it is completely ready • we need to get info on pump room from central dcs pvss

  9. 7. source drivers • software on dcs completed • need to connect HE+ driver to air pressure • cable from interface box to PC can not be screwed in, need to attach it • air driver on HB+ needed to be removed, until TK cabling is done

  10. 8. laser • would like to test it within a week, next priority after LV is done • clean up laser hut (ZEC?) • key for laser room, laza has the number, one needs to request key from natasha in cms secretariat

  11. 9. dss • if our dcs is dead (no heart beat in 2min) central dss will send signal to stop LV • if temp too high, we cut of LV (sergey prepares the device from HE-)

  12. 10. sx5-bbgb cabling • what we need to do: • HV for HE+, entire HO • buy 200m of PMA tube, 4cm dia, divisable

  13. 11. beyond HTR inputs • jeremy coming this weekend to work on switching to central daq

  14. 12. grounding • laza prepared prototype version of grounding, work in progress

  15. 13. HO/HE specific issues • yb+1 rbx ready to be installed • yb0 will be taken out today • after water test, install N2 inertion block • vladimir is doing LV, HV and DCS, OF for YB0, YB1 • special calibration units should be on YB0, YB1

  16. 14. cable preparations • TTC cables for HO on-detectors (part number 0265) were supposed to be 35m, they are only 30m long. • for now, we are installing 4m extensions. we need to decide what do to on final installation.

  17. 15. test beam • look for cables for two phi sectors to plug into two RBXes • we need to decide if are we using MTP-MTP or MTP-LC • R1 and R2 goes to one RBX, R0 has its one RBX • we need LV cable for R1 and R0 boxes, arjan will define the lengths
