ECAL Electronics

CMS and LHCC Reviews in 2001 revealed major cost overruns in electronicsLast RRB: Double speed of optical links – half cost of links – BUT insufficientAction - Mar 02: Alter electronics architecture to contain costs – generate L1 trigger primitive (25 xtals) on-detector rather than off-detector – reduce links and off detector electronics by factor ~ 10. FPPA: Final submission May02Electronics team reorganised, synergy between ECAL, Tracker & Preshower electronics

ECAL Planning

Goal: Apr 07 - ECAL complete and commissionedAdvance the detailed test (also system test) of 1st SM to mid-2003 (final analog electronics + emulated FPGA digital part)EB electronics mounted in 2004/2005 – calibrate at least 9 SMs in 2004EE and SE mounted in 2005/2006, calibrate 1 Dee in 2006

Electronics Schedule


Evolution of CMS Data Acquisition

New modular design of Event Builder - Break into a number of functionally identical, parallel, smaller DAQ systems

A 64x64 system is feasible today

Submit DAQ TDR end-02


High Level Trigger

Lvl-1 trigger in construction phase nowHLT running in processor farm – immense amount of data generated – exercising remote sites

Detailed analysis leads to < 400> ms/event (on a “PIII @ 700 MHz box”)Maximum flexibility: full event data available; using offline software (very important to understand HLT performance)

In terms of “2007” CPU units, this is 3*1.5 years away.CPU needs should be within reach

A 50kHz system at startup will need ~ 2500 CPU’s

N(CPU) = (0.4 sec x 50000 sec-1)/(2*2*2)= 20000/8 = 2500

At (staged) startup: 50kHz @ Lvl-1 and 80Hz to storageDiscovery physics “safe”. SM physics: ~ resource-driven

High luminosity: in DAQ TDR at end-2002

CPU time/evt L1-rate Moore’s law


Construction: Commitment Profile

By end of 2002 ~70% of the available funds will have been committed.62.7 MCHF of additional funds need to be committed soon in order to have a complete initial low luminosity detector in 2007.

Apr 02 RRB


~20 MCHF Staging/Savings ?

After RRB13 the Director of Research requested CMS to prepare plans for the case where 20 MCHF of the shortfall is not covered (with respect to the RRB13 shortfall of 67.9 MCHF) BUT with the hope of getting it later.

Staging/Saving already applied for 1st Physics Run ~5 MCHFHCAL: Reduce no. of longitudinal samplings 2.0 MCHF ME1/1a: Reduce no. of electronics channels 1.5 MCHFME4/1: re-stage electronics 1.5 MCHF

Additional Staging Considered for 1st Physics Run ~8.5 MCHF TRIDAS: Start with 50% of DAQ Capacity 8.0 MCHF Infrastructure: SCX Cooling and Ventilation Plant 0.5 MCHF

Additional Saving Under Technical Evaluation ~5 MCHFLV Supplies: Use 400Hz, 400V system 5.0 MCHF

Decision in June 2002.

TOTAL Staging/Savings ~ 18.5 MCHF

Proposal submitted to DoE March 15

0.9 MCHF already in Financial Plan.


High Luminosity Upgrades

10. Items (upgrades) for high luminosity ~ 19 MCHF

10.1 ME4/2 mechanics and electronics 9.210.2 ME4/1 electronics 1.510.3 ME4/1 assembly in PNPI 0.510.4 Restore ME1/1a electronics 1.510.5 Neutron Shielding (extra) 1.010.6 3rd Forward Pixel Layer ~2.510.7 5th endcap RPC layer ~2.0 10.8 Extra Installation Costs ~1.0

The decision to build many of these items will only be taken after inspection of the first physics data. This upgrade cost comes on top of the 62.7 MCHF shortfall. A plan for the funding of the upgrade will have to be worked out in due time. Basic ingredients are new collaborators or upgrade plans by funding agencies willing to upgrade items in which they have been working on.


April RRB (RRB14) Outcome

M&O MoU accepted, proceed with signatures

M&O cat A 2002 Budget accepted (1 MCHF with sharing according to nb of PhDs). No request for in kind contributions in 2002.

M&O Cat B: Must work out a way to share costs (by Oct RRB)

C&I costs accepted (positive report by scrutiny group). C&I profile peaks in 2003. Cash flow? 50% of C&I is manpower.

CMS Financial Plan well received. Expect ~ 54 MCHF additional funds for a shortfall of 62.7 MCHF.

Next step - Reach an agreement with Agencies by end June 02 on likely availability of funds (firm, less firm promisies), amounts and time profiles. Then prepare Financial Plan for Oct RRB (also discuss during LHCC CMS CR in Oct02)

Problems are being encountered but are also being overcome.

To watchProduction rate of DTs and RPCs – need to watch production rateStart of mass assembly of Si modules (Q4 2002)ECAL: Redesign of electronics chain. Very tight schedule.

Draft v33 CMS ScheduleMagnet test on surface Jan 05- Apr 05. Start lowering detector in May 05.CMS closed ready for 1’st beam 1st April 07.

CMS construction is proceeding at speed. A low luminosity detector can be ready for physics in 2007.

The low luminosity detector is the complete CMS detector, except the 4th forward muon station (ME4) and the 3rd forward pixel layer.
