Endcap assembly update C Buttar, R French UK-V Cluster RAL 8 th Sept 2004

Nikhef disk  cylinder assembly tooling

TPPCs 4x32ch PCBs Thermal plug access windows Cooling pipes LMT trays Service Handling

Disk insertion tooling

Disk  cylinder tooling Shielding foil added to cylinder Thermal feedthrough prepared Cylinder and stub wings assembled onto tooling 4 disk alignment tools made by Manchester  delivered to Liverpool Disk grabber-design by Nikhef- manufactured by Sheffield/Lancaster; tested with a disk CCDs and lighting now added and tested Disk fixations from Nikhef and Liverpool-delivered alignment target holders designed (Nikhef) and manufactured (Lancaster) z-alignment tool needs to be finished Still to do….. Disk-grabber and disk alignment, perform 2 nd test How to mount and de-mount the central beam concept ready, need to test

Cylinder  tooling Pre-aligment of rear stub wing mounting point Rear stub wing mounted onto frame Cylinder placed over beam and left on table with foam supports Cylinder bolted to rear stub-wing front wing offered up using sling for support and mounted Disk placed on disk grabber and cylinder aligned Disk moved through cylinder Very useful exercise! - lots of details to be sorted/have been sorted

Disk  cylinder insertion Capture and align a disk need to consider disk masses

Service status LMTs Testing of UK tapes at Glasgow Preparation of LMTs before assembly into trays  JT TIs Will be tested as part of LMT-TI harness at Glasgow First 100 delivered, full order soon ‘String test’ LV/HV  test cable  TPPC  TI  LMT  PPF0  wiggly tape  hybrid/module at Liverpool Fibres Lancaster has volunteered to take on reception testing Fibres for disk testing (D1+D2) at Liverpool, D9 at the end of Aug (?) Cooling pipes Now too late to assemble cooling on cylinder at Liverpool, now retro-fitted at CERN ? Assume no cooling pipes initially and connect direct to disk as for disk testing, then connect at STFT if pipes are delivered

TPPC string test (J.Voosebeld+P.Dervan) String test Test cable  TPPC  TI  LMT harness  PPF0  wiggly tape  hybrid direct to hybridString test TPP-C String-test on single channel test board complete TPP-C ordered, string test on 32 channel pre prod board (1ch only) complete try and do 2ch test ? (need additional LMT)

Service handling Thermal plug ordered and being manufactured in Sheffield (caravans!) PPF1 trays for LMTs in production PPF1 tray holders order placed last week-being modified temporary PPF1 for fibres Lancaster have volunteered to make this, awaiting design from Nikhef At Liverpool we need to ensure we can connect in the cold room Cooling-replicate disk testing system and connect direct to the disk-or similar re-evaluate when cooling pipes/connects start to be available

Test cable installation Test Cables for endcap testing installation started—Ray Thompson, Andy Elvin, Richard French Basic mapping ready

Thermal plug

Status, going forward Assembly tooling is ~ready needs to be tested –cylinder mounted and disk moved through on the beam –Still to do: 2 nd test run of disk alignment, capture and removal done but need accurate disk masses Z-alignment tool Removal and insertion of the beam interface to disk holder floor, bracing and wheels, move in and out of cold room scaffolding for working on the cylinder

Status, going forward Service handling is progressing –thermal plug being assembled – arrives in Liverpool 13/9 –LMT trays and tray holders in production –Still to do: DCS to be investigated Fibre holder design to be finalised Cooling, connect direct to disks at Liverpool, otherwise interfaces must be defined now to allow disk insertion+testing to go forward  assume HEX that we connect to disks/pipes at STFT so no longer need cooling pipes in service handling -how to make connections in the cold room-design manifold?  replicate disk test system and connect to disks –Need services (LMTs+Fibres) to start developing methods for putting services on what tooling is required how to make test-fibre connections !

Status, going forward Developing tests for disk  cylinder assembly –test cooling on disk with services –during assembly to check connections eg LMTs, check thermistors on modules Similar tests to those made on populated disks
