ECAL planning, 10 Jul 2003 AB YE1 +/- schedule: draft May 03 (assumed 3 month shift wrt v33) pivotal point is still EE/ES cable installation delay will impact HE- RBX connection
ECAL planning, 10 Jul 2003 AB Proposed routings passing critical areas are worked out in detailed designs and are checked on the integration model YE1 cabling

ECAL planning, 10 Jul 2003 AB YE1: some possible schedule hang-ups cooled cableway design & occupancy vs time ( need cartoons of cable-way filling vs time) procurement/manufacture of remaining cableways layout of YE 1 patch panel & cable service loops RE1/1 link board boxes and cables EE/ES cooling & cable definition for pre-installation latest mid 04. electronics definition. LV & HV system definitions LV regulators (rad tolerance, operating margin, noise rejection) LV cable noise immunity/rejection Patch panel “dummies” & cable storage Can we converge on a relatively conservative scheme which meets the constraints and gets all EE/ES cables installed on YE1+ by mid-04? What part of the EE/ES services can be installed earlier than this? extra expenditure may be justified to maintain a simple SX5 sequence!
ECAL planning, 10 Jul 2003 AB Cable chains: freeze occupancy in Sept 03 Patch panel on cable chain: fix definition by Sept clear to discuss cooling, gas, inertion, sniffers, grounding,other low count HV & LV collectively oversheathed cables requiring breakoutoptical fibres start by confirming cable count in YE1 chain (through cabling link-person)
ECAL planning, 10 Jul 2003 AB Precabling of endcap detectors Hadron Endcap Muon Endcap 1/1 (dummy) Preshower (dummy) EM endcap who is responsible for PP definition and dummy fabrication?
ECAL planning, 10 Jul 2003 AB Preshower design 2 completely cabled 1/2 disk (radiator + Si detectors) front & rear windows + inner drum (moderator)full disk pre-mounted before beampipe installation. detectors can be installed/removed without removing beampipe or moderator Rob Loos logical time to install ES detectors is (just) after EE.
