Trigger Concerns - Time!Trigger Concerns - Time!Trigger Concerns - Time!Latency:

• Endcaps: HE, EE, RE• Working on improved cable routings on detector• Revised layout in USC55

• Some improvement - already optimized & constrainedSchedule:

• Further Slippage of Underground Schedule• Solidifying plans for integration tests of trigger core in

Prevessin 904• Allows people to wheel crates out of testing labs into an

integration testing facility in same building for dedicatedtests and then back into the labs with as little disruptionas possible.

USC55 ChangesUSC55 ChangesUSC55 ChangesWork with Trigger Group:

• Reorganize RCT (& ECAL, HCAL) to put farthest phiin closest racks.

Work with G. Faber:• Move the racks by two units towards the IP on the top

and lower floor. Adapt all services to this new layout.• Add a cable support on both floors above the central

10 racks to the adjacent rows to diminish thecrossing length of cables.

Work with TOTEM:• Move one TOTEM rack (TOTEM Trigger) to S2 E11

since Roman Pot cables enter USC55 on 2nd floor• Minimizes Roman Pot Latency to Global Trigger

Trigger Upgrade RoadmapTrigger Upgrade RoadmapTrigger Upgrade RoadmapCMS Workshop at CERN Feb 26, 27:

• Gathered ideas from CMS• Just shown

Summer CMS Workshop Imperial Coll., July 12,13• Propose initial plan of Trigger R&D for FY05• Develop overall CMS plan for Electronics R&D

• Determine project areas and planning for developmentLong Term:

• R&D 2005-7• Prototype/Test 2008-10• Construct/Install 2010-13

Note: Ideas developed could be useful/neededsooner than we think!

Trigger ConclusionsTrigger ConclusionsTrigger ConclusionsNews:

• Moving from Prototypes to production• Confidence from successful integration and structured

beam testsConcerns:

• Latency -- relief from shorter cable paths + USC55• Installation time -- risks for further delays?• Software & Planning needed for production/integration

Actions:• Trigger Software Meeting with online group yesterday• DTTF/WS/GMT/GT Review in Vienna on April 19• Electronics Systems Review May 7• Plans for Trigger Core Rack Test in Prevessin 904
