TRD & Upper TOF Upper TOF: 1) Upper TOF mounted to TRD TRD MLI TRD TRD GAS System 1) TRD with M-structure lowered onto USS & bolted 2) Gas system installed and plumbed to TRD 3) MLI enclosure 4) Crates & Cabling
Lower USS Integration (5) Lower TOF 1) Reinforced with Jig, rolled underneath AMS & lifted into position. Struts adjusted and bolted in place 2) Crates and Cabling (6) RICH 1) RICH lowered, shimmed and bolted to lower USS 2) Crates and Cabling (7) ECAL RICH/Lower USS assembly lifted & lowered onto ECAL –then bolted in place Crates & Cabling These steps can be done in parallel with upper USS integration and only need to be done once (ie. No pre-integration)
Upper & Lower Parts Integration Upper Part Lower Part • Lower part rolled underneath Upper • Lifted in place, shimmed, and bolted • Electrical connections made
De-integration for Flight Magnet Temporarily remove mid-brackets and lower struts
Temporarily Reattach Top Brackets to Upper USS Move Main Ram & Wake Radiators outward to allow installation of Flight VC & Magnet
Radiators & Electronics • Zenith radiators with plumbing attached assembled in quadrants: bolted to TRD upper honeycomb and heat exchangers to Cryocoolers • Plumbing secured and insulated • Main radiators: jigs removed from self supporting crates and radiators bolted • Tracker Radiators: Jigs holding heat exchangers removed and radiators lowered and bolted to USS and exchangers Zenith Radiator Tracker Radiator Tracker Radiator RAM Radiator WAKE Radiator RAM Radiator
AMS Assembly Area Clean Room 867 Everything in the AMS Assembly Area/Clean Room 867 needed to begin the STA integration will be ready no later than (NLT) February 2, 2007. • Operation as a Clean Room (air conditioning, filters, sealed & positive pressure) will be ready in May, 2007 • Rotation Assembly Stand (RAS) delivered, assembled, installed, and ready for use • Scaffolding delivered, assembled, and ready for use
AMS Assembly Area Clean Room 867 • Information provided in the Resource Requirements checklists has been used to order common use supplies and to estimate facility requirements • Work area required – with & without crane access & special access • Crate storage area, volume, and environment • Tables & chairs • Storage cabinets & open shelves • Air bearing pallet requirements • Cleaning fluids/supplies & vacuum cleaners • Supply gases (He, CO2, N2, Compressed air, etc.) • Fans for ventilation/cooling of hardware & personnel • Power requirements • ??? • If you didn’t ask for it on the checklists, do NOT expect it to be provided!

AMS STA Integration Hardware • STA VC integration with the STA Magnet (Cold Mass Replica - CMR) was completed in December at SM • STA VC Arrived in Terni/INFN for Sine Sweep Tests on January 10th • Test hardware was previously shipped to Terni and testing has been completed • Ship STA VC to ESTEC for Acoustic Tests - March ’07 * • Return to CERN for integration in USS – late March ’07 * • * Depends on results of STA VC/CMR sine sweep & acoustic tests
AMS Flight Integration Hardware • Flight USS is complete and has arrived at CERN with the Primary Support Stand (PSS) and the Primary Lift Fixture (PLF) • Flight Vacuum Case is complete and will be shipped to SCL/SM when they have room in their facility to accommodate it (after Flight Cryomagnet tests are completed and the SFHe Tank is delivered and SFHe leak tested)
Pre-integration of STAs in the Flight USS Prior to STA VC Arrival • STA Hardware Pre-integration in Flight USS • On-line integration of the STA Crates/Radiators on the USS will begin the week of February 5, 2007– before the STA VC arrives • This allows work to proceed even if the sine sweep & acoustic tests are delayed • 10T crane installation will be delayed until after STA Pre-integration is complete at beginning of March • If necessary, the USS/STAs in PSS will be moved away from crane installation • There are ~3-4 weeks available in March to use the flight USS & STAs for fit checks, cable & plumbing runs, measurements, etc.
Pre-integration of STAs in the Flight USS Prior to STA VC Arrival • STA Hardware assembly in Flight USS (cont) • Integration of all STAs in USS to be completed by mid-April ’07 * • Even though the STA VC delivery to Terni slipped ~5 weeks and the RAS readiness at CERN slipped ~3 weeks, this is only ~2 weeks later than previously reported at AMS TIM on October 27, 2006 • Ship USS with STAs to Munich/IABG in April ’07 * • Static Tests • Modal Tests • Return USS with STAs to CERN in August ’07 * • * Depends on results of STA VC/CMR sine sweep & acoustic tests and USS/STA modal & static tests
Interference between Flight VC/Magnet & Electronics Crates during Final Flight Installation • R. Becker/MIT, J. Kastelic & P. Mott/JS, & R. Stafford-Allen/SM to determine how much room is required to clear the Flight VC/Magnet as well as how much room is available by Jan 29th. • Provide estimate of additional length required for lower inter-radiator cables to M. Capell & A. Lebedev • Final cable routing must accommodate additional length • Be sure there’s no interference with hardware mounted outboard of crate jigs during pre-integration activities • Upper inter-radiator connections will be disconnected because the additional length will be too much additional weight • C. Lauritzen/JS to determine if there is any problem on the USS if the brackets are temporarily re-attached at a wider position by Feb 5th • M. Molina/CGS to determine if Radiator brackets are OK by Feb 5th • Consider using blocks/spacers under the brackets and reattaching the lower struts • K. Bollweg & J. Heilig will arrange trial test using STA Crates/radiators in late February
Pre-integration of Detectors on STA VC & USS prior to Cryomagnet Arrival • All the detector groups have continued to evaluate the pre-integration proposal and have agreed that it should proceed according to the schedules thoroughly discussed at this TIM • Current estimate of Pre-integration start: August, 2007 • Pre-integration finish: December, 2007 • Optical fibers between ACC & VC for TAS will be installed • Constantly monitor the Cryomagnet progress and decide how much more flight hardware to pre-integrate • Current estimate of magnet delivery to CERN: February, 2008 • Do as little de-integration as possible – just in time to remove the STA VC and install the Flight VC & Cryomagnet in the USS
Pre-integration of Detectors on STA VC & USS prior to Cryomagnet Arrival • Consider removing the STA VC, Tracker, and ACC from the USS as an assembly so parallel work can continue during Flight VC/Magnet installation • Use VC rotation fixture and wheels/brackets developed at SM • This could shorten deintegration by 2-3 weeks; thus allowing combined cosmic ray testing to be extended
Final integration of Detectors on Flight VC & USS after Cryomagnet Arrival • All detectors must be integrated and functionally tested with the Flight VC and Cryomagnet at CERN by July, 2008 • Beam tests at CERN (~1 month reserved) • Thermal Vacuum Tests at ESTEC (~3 months reserved) • EMI Tests at ESTEC (~1 month reserved) • Delivery to KSC in December, 2008
