1 Preparation for ATLAS SCT/ID Endcap Completion at CERN Jo Pater Manchester, 4 January 2006

2 Jo Pater - Manchester 'Christmas' meeting - 4 January Early 2005: End of SCT Endcap System Tests ¼ of an endcap disk with modules, services & peripherals Aim: to examine performance in realistic surroundings –develop effective grounding and shielding scheme –discover problems, feedback into designs Aims were met; paper in preparation (to finish in 2006) on both barrel & endcap systemtests. The endcap system test sector with 4 modules

3 Jo Pater - Manchester 'Christmas' meeting - 4 January SR1 Building Preparation SR1 = Building on ATLAS site in which inner detector is being constructed –Jan-Aug 2005: testing of completed SCT barrels –July-Sept 2005: SCT 4-barrel assembly –1 st half of 2006: Barrel SCT-TRT integration & combined testing SCT endcaps will arrive, be tested and integrated with TRT 2 distinct physical areas of activity for SCT: –‘test area’: readout and infrastructure commissioned in early 2005 using system test sector This area was used for individual SCT barrel testing and will be used for all combined TRT-SCT testing. Manchester (JP, WP, AP) contributed to test-area commissioning effort by laying and testing fibres and cables, installing interlocks and commissioning module readout –‘assembly area’: commissioning started mid-2005, nearing completion now To be used for individual SCT endcap testing and assembly Most of the commissioning work (planning and execution) being done by Manchester and Geneva Universities.

4 Jo Pater - Manchester 'Christmas' meeting - 4 January SR1 Assembly-Area Preparations The basic plan: Two 1-disc (132-module) systems located in this part of SR1 clean room. Each system: –3 RODs, 3 PS crates: modules –1 DAQ PC + shared PC for DCS/environmental –Evaporative cooling –Cable and fibre handling First system needed by mid-February 2006 Second system needed by mid-April 2006.

5 Jo Pater - Manchester 'Christmas' meeting - 4 January Status of Assembly-area readout For 1 st endcap: –RODs, power supplies installed and operational Still need to install final cables and fibres on support structure –Evaporative cooling installed and operational Need to install final pipework from cooling rack to test box location –Other remaining jobs: Install ground distribution Install dry-air distribution Set up DCS (slow controls, interlocks, environmental monitoring) –Should be no problem to be ready for mid-February 2 nd endcap system: basically same jobs remain (will be done in parallel) plus: –Add 2 more RODs to readout crate, test with sector –Add sides and heat exchanger to power supply rack –Build services support structure (materials ordered) –Will be ready by mid-April

6 Jo Pater - Manchester 'Christmas' meeting - 4 January : Completion of ATLAS SCT Endcaps Mid-February: arrival of 1st endcap from Liverpool 3.5 weeks for reception testing –Several days for unpacking and visual inspection –Leak/pressure tests of cooling circuits –Continuity checks to insure connectors still plugged in –Full electrical readout of one or more disks After verification that no damage in transit: –Installation of thermal enclosure –More electrical testing –Insertion into TRT –Combined SCT-TRT testing –For details see Paul’s talk this session Repeat with 2 nd (Nikhef) endcap, starting probably mid-April.

7 Jo Pater - Manchester 'Christmas' meeting - 4 January Later-2006 plans August: I move to Manchester –start work on FP420 aim to set up a system test similar to atlas sct –ATLAS physics –get involved with atlas ID upgrade ??
