VPTs Electronics and Integration SC assembly Dee4 H4 and H2 Planning Conclusions


VPTs

VPT contract completedETH-Z, RAL, Brunel, Bristol, IHEP, INR, PNPI, UVa, Split, RIE

16100 VPTs deliveredCMS Gold award to RIE yesterday

15616 tested at RAL at 1.8T1820 tested at Brunel at 4.0T

~10700 VPTs now at CERN~5000 reception tested under HV


EE Electronics

Supercrystal to Motherboards

HT filter card mass production launched with Elfab in Dec 2006

120 cards received yesterday. 500 cards/m. 3120 cards by end Sep.

SC umbilical cable mass production launched at CERN last week (Cegelec)

24 prototype EE motherboards produced. 2 fully tested, rest being appraised

EE Motherboard mass production started at Ascom

Internal SC mounting

All umbilical, fibre optic and HT card supports either produced or nearing end of production

All porte-ferrules for the laser fibres produced


EE VFE cards to fibre optic readout

VFE card production completed last year

LVR cards completed and delivered

All VFE and LVR housings delivered to CERN

Order placed for Gap PadStart VFE card calibration in Lyon as soon as possible

All 800 EE FE cards produced and tested at LLR – being sent to 867

All GOH and ribbon fan-outs tested and ready at CERN

EE TRLBs – final components need to be mounted

Mechatronics & Monitoring

Mechatronics

All EE cooling bars prepared. All local manifolds for the cooling blocks due in March

6 (of 10) cooling blocks ready for Dee4

Support plates delivered for Dee4

First dry assembly tests for Dee4 carried out

Polyethylene moderator

Moderator for all 4 Dees to be delivered in March

Monitoring

3 level 1 fanouts prepared for Dee4Adapted to take VPT stability pulser fibresMounting on Dee4 possibly next week

‘Double MEM’ for Dee4 at H4?

EE Mechanics

OPAL frames and Dee rotation equipment

SC have given permission for the use of all OPAL frames and lifting beams, after load tests

https://edms.cern.ch/document/819480/1

Permission based on results from impressive FEA study carried out by Alexander Riabov (IHEP, Protvino)

Rotation test and load tests on Dee1 OPAL frame in March

Delivery of lifting device in March


EE Mechanics

Loading device for Environmental Screen

Completed by New Ingenia SA

Delivery to CERN this week

Device attached to OPAL frame~1m stroke wrt backplate

Allows screen to be safely loaded over the SCs for Dee horizontal or vertical


SC assembly

SC status

Dee4425 EE crystals glued to VPTs17 SCs assembled out of 20 14 HV tested

Dee130 EE crystals glued to VPTs3 partial (2x5) SCs assembled

Crystals awaiting useDeliveries in Dec 2006/Jan 2007125 BTCP125 SIC


Dee4 SC assembly

Assembly progress at http://hepwww.rl.ac.uk/CMSecal/Dee-assembly-status.htm


SC test stands

SC tests and umbilical trigger mapping

Have successfully run the UVa pulser system and ECAL DAQ with a preshower CREPE board

Complete system controlled from a single PC

Would like 1-2 further CREPE boards for additional test stands

Dee4 SCs assembled for testbeam

Each SC assembled with VPTs from within a specific yield range

SCs assembled for Dee4


H4 and H2

H4

Dee4 to H4 in MayDetailed design of mount on H4 turntable nearly complete

20 SCs = 500 crystals UVa offer for testbeam coordinator: Alexander Ledovskoy DAQ/DQM Matt Ryan, Alexander Ledovskoy, Yvgeni Vlassov CCS code and control room monitoring need to cope with - EE trigger mapping into the motherboards

- Readout 5 EE Trigger GOH/FE later in the year - Token ring layout specific to Dee4

H2 permanent facility

4 SCs in front of HE

Use old E0prime mechanics2 existing SCs at RAL and UVaAssemble 2 further SCs

Project led by HCAL communityThey will design/make all infrastructure interfaces at H2


Dee4 and E0prime planning

All Dee4 and E0prime preparation in Crystal Palace


Dee1 by Autumn 2007

Changeover to EE crystal gluing in Bldg 27

Modify 40-50 multiboxes from EB type to EE type

End of EB activities in 867Start of EE integration in 867

Bldg 27 available for EE assembly

Parallel work mandatory:SC loadingHV and LV cablingUmbilical trigger mappingCooling bar mountingVFE/LVR/TRLB mounting


EE - Conclusions

ECAL Endcap mass production underway

Good progress on Dee4

Testbeam programme in 2007 will extend the calibration and detailed response studies on the CMS ECAL out to = 2.5

Dee1 for CMS by Autumn 2007 – parallel activities essential
