Issues - alorimeter Trigger 1.2 Gb Serial u Link from H/EAL to Regional Trigger Originally fibers from detector direct to trigger New MS R&D effort to switch from fiber to wire to adjacent crates Major improvement in access, environment, power, support Engineering load on Receiver ard project Moved Link to Mezzanine ard on Receiver ard Added 1 FTE EE from U.Wisc. PSL to work on this New WBS for this task at cost < $100K This engineer also serves as reserve after Link done Vendor Support Vitesse shifting to external ASI engineering support Experienced customers can still find internal support (small load) No Impact on ASI production runs As per Lehman '98: contacting other vendors (AM, TriQuint, Fujitsu) Final Algorithms & Tower Geometry Required for final designs of Boards, Backplane & ASIs Agreement on trigger tower geometry for HAL & EAL Agreement on final electron & jet algorithms Documents written & being circulated 20
Issues - Muon Trigger Peripheral rates Originally LT circuitry on chambers connected to separate Port ards Now all Strip & Wire LT Boards, Mother Boards, Muon Port ards moved to crates on the periphery of the iron disks Major improvement in access, environment, power, support Required full system redesign -- now complete System redesign also handles ME1/1A split strips using added Muon Port ards (48 60) Overlap Region Both S & Drift Tube segments must be used for 0.9 < η < 1.2 Agreement reached with Barrel Muon groups (Vienna & Bologna): 2 separate Track Finders with programmable sharp η boundary Data sharing between Track Finders Finders Requirement of separate sorter for S & DT muon tracks ost estimate < 100K New onceptual design documents are being circulated Design eliminates extra signal distribution & reduces crates (8 6) and sector receivers (48 24) 21

ommittee oncerns & orrective Actions From May 98 Lehman Review: Add al. Trig. & S Trig. rate Tests &S for al & S Trig rate tests added to MS Project Planning Done before MS Trigger TDR planned for end of 2000 ontinue work on limited loss of Muon Trigger efficiency in the overlap region. onsiderable effort had been put into simulation and design efforts in this area. Documentation of this effort is found on the web at: http://www.phys.ufl.edu/~acosta/cms/wang_sim_12_98.pdf http://www.phys.ufl.edu/~acosta/cms/acosta_tf_cern_12_98.pdf Watch ASI availability issues, as early procurement may become necessary. Working on plans to procure an entire ASI run after performance verification Alternative vendors sought for each ASI to avoid single vendor dependence. ontinue to monitor closely the Level 1 trigger latency. Full day workshop ( Synchronization Workshop ) held at ERN on Nov. 11. Major Topic was Latency -- thoroughly reviewed -- transparencies on web: http://cmsdoc.cern.ch/~wsmith/agenda1198.html These concerns have been addressed 23
