JH happenings

Last week:

Bad cold since Weds. last week, now improving…

Wrote up muon Phase 2 upgrade plan for official document

SUS-13-013 ARC + authors: smoothing of 2D limit plots – “Pieter’s tool” versus “official procedure” to be resolved… new paper draft

today or tomorrow?

CSC(+GEM) electronics & trigger workshop created for Sept. 30-Oct. 1 at TAMU

This meeting:

CSC system overall highlights (report for XEB tomorrow)

Discussion

of overall status of UCLA boardsSlide2

CSC status report for XEB

General

:

a workshop on electronics plus trigger planning for Run 2 will be held Sept. 30-Oct. at Texas

A&M

ME4/2 chamber update:

57

(out of 67) chambers have been assembled, 48 chambers have been fully tested and are ready for installation

.

ME1/1 electronics:

found and corrected a problem with the reset of optical transceivers in the ODMB that had sent hundreds of stray packets to the DDU upon hard reset. The ODMB has more features yet to be implemented in firmware, but with the electronics working well for event readout, attention focuses now on implementing the standard "STEP" tests in software at building 904 and the SX5 refurbishment facility

.

ME1/1 refurbishment:

9 of the 72 chambers extracted have now been fully refurbished at SX5, and 4 of them are also fully tested and working (+3 and +1, respectively, from last week).  A steady state rate of 2.5 chambers/week will be needed in order to stay comfortably ahead of installation that starts in mid-October. Some infrastructure delays are being encountered in establishing a long-term test stand at SX5. The two-chamber demonstrator is expected to be installed during next week (26-30 August).Slide3

Julie inventory (Aug. 13

, updated)

ALCT-384

904:   47 boards already installed on ME4/2 chambers

           25 spare boards

             4 bad boardsISR:    4 boards registered in CSC database, but real location unknownSX5:   1 board registered as “dismount” and 1 registered as “sent for repair” Real locations are unknownUXC:   1 board registered as “dismount”, but real location unknown.UCLA: 12 old bad boards received from CERN to be repairedUCLA: 26 new boards did not pass tests and 1 board used as test board.        ALCTM-S6904:     31 installed boards            43 Spare boards (13 needed to replace the old E600 for ME4/2)              1 bad boardSX5:    3 installed            37 spare boardsUCLA: 50 more spare to be tested, plus 20 failed testsALCT-672904:    13 spare boardsISR:     5 boards registered as received, but real location unknown              1 “dismounts” board, real location unknownUCLA: 5 bad boards received to be repaired

ALCT inventory analysis

Bottom line on spares:

Bare mezzanine boards:

no particular shortages

of Virtex-E600, -E1000, or Spartan-6 (as S6 testing continues…)

ALCT384 units: 0 spares now, but potentially 41 spares after repairs (14% of 288)26 new boards failing tests, 12 in UCLA Elab “to be repaired”, 4 to be returned from CERN, -1 to be used as 2nd tester reference boardNot counting 6 in Elab perhaps “unrepairable”, or 1 used as tester reference board, or 5-6 net with “location unknown”ALCT672 units:13 spares now, potentially 18 spares after repairs (17% of 108)ALCT288 units:24 spares now potentially 26 spares after repairs (18% of 144)Action items:Continue fixing at UCLA Elab!B904 replace E600 mezz with S6 on 13 chambers, solder 2 capacitors/new-ALCT for Andrew’s fix, starting next week during re-testing (see his talk at ME4/2 meeting tomorrow!)Misha will pull off a few bad ALCT from CMS, Julie will keep looking for ~10 that are missing

4 bad ALCT384 units at B904 and 1 bad ALCT288 unit at SX5 should be sent to UCLA for repair

Should have at least a few working spare Virtex-E1000

mezz

cards at UCLA for future repairs: are these already in the lab, or ship some of the 13 spares that are at B904 back to UCLA?

Debugging S6 mezzanine cards that failedSlide5

TMB and RAT inventory analysis

TMB:

21 spares now, potentially

58 after repairs

(12.4% of 468 in CMS)

RAT:2 spares now, including full ME4/2 installationNB 2 used on Elab test stand, should be 10 more at UCLA with unknown status…Need to build more, originally estimated 56 to be built58 spares = 10.7% of 540… on the other hand, never have had any broken RATs…6.4 full peripheral crates of spares (9 per crate)To discuss with Loveless, Misha: aim for 27 spares (5%) = 3 VME crates?Action items:Find out status of 10 RAT boards left at UCLA (working, broken, untested?)Start to plan for production of (15? 25? 56?) more RATMisha is replacing 3.3v fuses on all TMB…
