17. ECAL Electronics CMS and LHCC Reviews in 2001 revealed major cost overruns in electronics Last RRB: Double speed of optical links – half cost of links – BUT insufficient Action - Mar 02:Alter electronics architecture to contain costs – generate L1 trigger primitive (S25 xtals) on-detector rather than off-detector – reduce links and off detector electronics by factor ~ 10. FPPA: Final submission May02 Electronics team reorganised, synergy between ECAL, Tracker & Preshower electronics TDR TP 91000 Data and Control Links 800 Off-detector Trig/DAQ Boards 12000 Data and Control Links 120 Off-detector Trig/DAQ Boards

19. 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

20. High Level Trigger Lvl-1 trigger in construction phase now HLT 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 CPU time/evt L1-rate Moore’s law At (staged) startup: 50kHz @ Lvl-1 and 80Hz to storage Discovery physics “safe”. SM physics: ~ resource-driven High luminosity: in DAQ TDR at end-2002

21. Construction: Commitment Profile Apr 02 RRB 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.

22. ~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 MCHF HCAL: Reduce no. of longitudinal samplings 2.0 MCHF ME1/1a: Reduce no. of electronics channels 1.5 MCHF ME4/1: 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 MCHF LV Supplies: Use 400Hz, 400V system 5.0 MCHF Decision in June 2002. TOTAL Staging/Savings ~ 18.5 MCHF

23. Additional Collaborators Serbia Corner Pieces Magnet approved in Mar CMS Week 400 kCHF protocol agreement Milan, INFN ECAL approved in Mar CMS Week Naples, INFN RPCs approved in Mar CMS Week Brazil YE4+ farmYE4 funded (500 kCHF),application in 2002 Ireland ECAL electr.?, farm Visited CERN 18-19 Feb Expect application in mid-02 Mexico Silicon Tracker Expect application soon NZ farm+Pixels Applic. received, Pres. in June Visit at CERN S. Thompson Thailand ME electronics boards in progress US-NP (HI) TriDAS, farm Successful workshop in MIT 8.02 Proposal submitted to DoE March 15 0.9 MCHF already in Financial Plan.

24. High Luminosity Upgrades 10. Items (upgrades) for high luminosity ~ 19 MCHF 10.1 ME4/2 mechanics and electronics 9.2 10.2 ME4/1 electronics 1.5 10.3 ME4/1 assembly in PNPI 0.5 10.4 Restore ME1/1a electronics 1.5 10.5 Neutron Shielding (extra) 1.0 10.6 3rd Forward Pixel Layer ~2.5 10.7 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.

25. 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)

29. Conclusion Magnet: Yoke finished. Conductor and winding well advanced. 1st coil delivered end 02 with 6 months delay. Not critical: HCAL, Endcap Muons : construction on schedule and well advanced. Problems are being encountered but are also being overcome. To watch Production rate of DTs and RPCs – need to watch production rate Start of mass assembly of Si modules (Q4 2002) ECAL:Redesign of electronics chain. Very tight schedule. Draft v33 CMS Schedule Magnet 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.
