YE1 +/- schedule: draft May 03(assumed 3 month shift wrt v33)

pivotal point is stillEE/ES cable installation

delay will impactHE- RBX connection

ECAL planning, 10 Jul 2003 AB

Proposed routings passing critical areas are worked out indetailed designs and are checked on the integration model

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 definitionsLV regulators (rad tolerance, operating margin, noise rejection)LV cable noise immunity/rejectionPatch 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 discusscooling, gas, inertion, sniffers, grounding, other low count HV & LVcollectively oversheathed cables requiring breakout optical fibres start by confirming cable count in YE1 chain (through cabling link-person)

Precabling of endcap detectors

who is responsiblefor PP definitionand dummy fabrication?

Preshower design

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.
