1,5 m M2 prototype at LNF transport & positioning scale 1:4 !!!

precision pin glue rivets assembly steps

3 panels 4 panels

photogrammetry (50  m) in horizontal position (holes for rivets are our main reference) delivery of two half-stations at the same time: long term stockage (up to 3 months) in Bld 156

- panels arrival at Bld lifting tools installation - panels transport to the pit installation sequence 1 panel in vertical position 2 balconies fixation 3 copper braid fixation 4 cable supports 5 panel lifting 6 positioning of the following panel 7 gluing & riveting 8 safety electrical soldering 9 check of some balconies alignment (with ruler)

- panels arrival at Bld 156 (M5 middle November; one wall every two weeks) - lifting tools installation (beginning of each installation week) - panels transport to the pit (in parallel with installation of lifting tools) installation schedule 1 panel in vertical position 2 balconies fixation (30  1 hour) 3 copper braid fixation (30 m  1/2 hour) 4 cable supports (100  1 hour) 5 panel lifting (1/2 hour) 6 positioning of the following panel (1/2 hour) 7 gluing & riveting (1 hour) 8 safety electrical soldering (1/2 hour) 9 check of some balconies alignment (with ruler) less than one working day for each panel: one half-station a week

beginning installation can delay due to lifting tools procurement (new supports + FC) PLANNING M5 (+M4?) cryo side installed before Christmas restarting middle January switch to pit side on February ending M2-M5 beginning March M1 in stockage area (or immediately after M2-M5 installation)

status of the cabling materials procurement (middle October 2005) supports: ordered LVDScable: waiting for a big prototype connectors: ordered assembly: at CERN (1/3? 100%?) ECS cable: see LVDS connectors: soon ordered assembly: during vestition ? HV cable: probably soon on CERN catalogue connector:... assembly:... LV cable: waiting for a sample to be submitted to SC connectors: ordered assembly: commissioned GNDbraid: ordered

installation philosophy (possible scenarios  to be decided) LVDS:middle November measurement of actual length if realistic then assembly (fixed length) with connectors and capacitor on shielding installation starting on TB side (smaller space for extra lengths) if not assembly double length cables with two TB side connectors installation + cut + re-connectorization on chamber side + re-test ECS: assembly with nominal length (pulsing delay must be known) installation if too short/long  moved to closer/more distant chamber + re-labeling LV:assembly with nominal lengths (equal lengths from each PS source) cable recuperation “somewhere” HV:one cable/chamber + patch cords length ??? gas piping: copper pipes cut on situ distribution boxes screwed on the wall (over cables, under chambers)

installation sequence (a possible scenario  to be decided) 0 grounding braid already installed 1 LVDS on the wall (xxx/half station) 2 ECS on the wall if space is available 36 10/12 mm vertical piping 3 gas 36 distribution boxes (1 – 2 weeks/half station) 276 chamber connections 4 LV under balconies (supports?) 5 HV under balconies (supports?) 6 cooling ??? schedule ??? ??? how much parallelism ???

installation configuration (before June 2006)

MPO cassette 6 adaptators MPO-MPO Optical fibres (clock, TRG, DAQ) 12 fibers ribbon 1 fiber with SC connector MPO connector 96 fibers cable (8 ribbons 12 fibers each) 12 panels crate

+ long distance cabling (procurement phase...) MARATON 385V + controls + patch panels CAN powered and non powered links + patch panels HV long distance cables (???) + short distance cabling (procurement phase...) MARATON 385V + controls + patch panels optical patch panels and patch cords in ODE crates LV patch panels HV no more patch panels (?)

chamber hanging system (to be designed from scratch) target on sensitive area centre (<0,5 mm)

chamber installation sequence (to be agreed) 1chamber transport to nacelle 2leveling on the nacelle with the hanging system 3gas, HV, LV, gnd, ECS, LVDS connections 4translation on balconies 5spacers (nominal height) under chamber 6fixation 10 chamber/day 4 on one side + 6 on the other (to be checked) start from wall bottom 10 chambers survey at the end of the day

schedule: survey: 1 hour every 10 chamber

tests on mounted chambers (when?) connection test CARDIAC - TB (pulsing with SB) LV connection test (measuring current) gas leakage test... how? HV test (measuring current) switch on (?)

steps of electronics commissioning (to be decided) SB already installed IB installation (start when man power will be available) ODE installation test ODE CANbus link test of IB – ODE connections DAQ test using ODE histograms collected with noise optical transmission test to L0 trigger optical transmission test to DAQ switch ECS/L0/DAQ on (?)
