Project Cost Overview • Boards 3&4 (production boards-130 each type )

– Eng. changes and designer layout work – Done– Tech time to place POs and gather parts, place POs for PCBs/board

assembly.– Tech time for functionality testing at FNAL. Eng/tech time for debugging.

Shipping to CERN.– Radiation Testing (chips at CERN, CCMs at MGH)– CCM testing at 904: Eng. Time+Travel + Physicist Travel + student COLA– I&C at Point 5: Russian Tech(s) time + student COLA (2)

• 1 Teams of 2 Techs to harvest and reinstall CCMs (Arefiev + Smirnov/Epshteyn (if available)) + 2 students to modify CCMs and test

3

Production Boards 3&4– 108 CCMs needed for HB/HE/HO

• Full Production – 130 boards of each type (includes spares + test stands + test beam)

• 130 additional along with 25 prototype

– PCB fabrication (2 weeks)– Parts procurement (3 days – 1 week)– PCB assembly (2 weeks)– Board testing + debugging (20 days) [tech + physicists]– Should take 2.5-3 months after project approval/funding

(slower due to holidays). Parts procurement can start as soon as project is approved, but some parts have long lead-times.• If rad testing is required, it will need to be done simultaneously

to meet the installation schedule.

I&C Summary

• CCM installation• CMS has scheduled access time for the jumper

intervention to resolve the RBX data loss problems– CCM will already need to be unstacked. Swapping out boards

3&4 is straightforward

• 130 sets of new Boards 3 & Board 4 will be ready (tested with 10 day burn-in) by 1 May 2013

• There is sufficient access to have extended functionality testing time in CMS in the proposed CCM intervention plan

• HCAL is in close communications with TC for coordinating the LS1 activities

I&C Cost estimate• Labor needed (Jan-Aug)

– Skilled techs to remove/install CCMs from RBX (2-3 Russian techs)– 2 teams of 2 students for work in 904 (4 students total – could have international

contribution here)• Test and burn-in CCM boards • Stack/unstack of CCM cardpack• Clipping jumper• Install new Boards 3 & Board 4• Test modified CCMs

• Labor in current LS1 planning for CCM jumper work (US/Protvino) • Russian techs • 2 students

• Additional 2 students needed for CCM Board 3&4 work • International HCAL may provide the additional 2 students needed ($0 cost)• If not, the incremental cost is COLA for 2 students for 9 months (US rates)

– 1000 kCHF x 9 x 2 = 18000 kCHF (x1.1 for exch rate) = $19800

• If needed, we can provide 1 physicist for testing at CERN• $8k travel (per month)

• Total labor needed for I&C is an incremental change to the current US HCAL LS1 labor plan

• $19800 + $8k = $27800 • Cost range ($0 -$27800), depending on international support and required physicist travel support

Summary• New Board 3&4 design will make the CCM more robust to QPLL

failures – This redundancy is built into the new ngCCM but did not exist in the

old design.• CCM production schedule and I&C plan is tight, but achievable

– The full 130 sets of Board 3 & 4 will be tested/burned-in by May 1, in time for installation

• Overall incremental cost in terms of CCM interventions already planned in LS1 (jumper removal) is not large.

• Cost of the production quantities of new CCMs should be looked at in view of the cost to support the CCM hardware in the past– 1 FTE (Dick + grad student) per year

• While this maintenance need won’t disappear completely, we hope it will be greatly reduced to <<1 FTE
