AMS Cabling CERN Prevessin 893-1D020 December 6, 2006 Agenda 1) Brief overview -Show Plumbing and VC ring-mounted-hardware -AMS overall -Common cables (Mike & Alexei) -Subsystem / detector cables 2) Mock-up tour. (To understand what the starting point for Cad modeling is) 3) Discussion on how best to organize the activity: a) Central CAD designer? Who is willing to CERN for the length of time required to do the job b) under what conditions? c) How best to organize the detector cabling with detector CAD designers remote from CERN.
Electronics subsystem Cabling (integration team +M.Capell+A.Lebedev A.Roishkov) Lower USS Cabling (F.Cadoux, C.Guandalini) TRD / Upper-TOF cabling (Isatec, C.Guandalini) Zenith Radiator Plumbing (? CGS?) Tracker Cooling Plumbing (A.Alvino, E.Perrin, C.Gargiulo) NASA / Shuttle / ISS Cabling (Jacobs: J.Kastelic) Tracker Cabling (E.Perrin, A.Alvino, D.Rapin, CERN integration) ACC (Isatec) UGBS (R.Becker)
Starting points for cabling model:
Magnet and External Magnet hardware
ACC Cabling To S-Crate Al-Cover on PMTs (schematic)
ACC Cabling To S-Crate Al-Cover on PMTs
Cable clasp On the border of VC ring
TRD And ACC Cabling And Thermal Insulation Al- Cover
Dallas sensors (DTS) on ECAL back panels To be fixed on ECAL before EIB assembly (accessibility) Intermediate bracket BP4R routing (… BP5R is about the same routing) DTS routing ECAL Bracket DTS board (glued on End caps) Intermediate bracket 1
ECAL cabling to the Crates ECrate (DAQ,EDR…) HV cables to HVBrick LUSSII ECAL ECAL Integration on LUSSII DTS cables (from ECAL brackets to Crates) DAQ Cables
Still to be assembled on ECAL EIB Cabling + Radiator fixation (36 Boards / 20 Mechanical supports) EIB frame “heaters” cabling + Terminal Bock DAQ cables HV cables Trigger cable support DAQ cable support EIB frames
As you can see, except for F. Cadoux’s lower USS model Most of the cabling models are under developed or missing!..
Mock-up Tour!
How do we resolve Cabling? Tasks: Cable routing Mockup Cable routing CAD Bracket design, calculation, manufacture 3) Discussion on how best to organize the activity: a) Central CAD designer? Who is willing to CERN for the length of time required to do the job b) Under what conditions? (only work share etc, not contractual) c) How best to organize the detector cabling with detector CAD designers remote from CERN.
Tasks: Critical Cables: Installation Priority??! 1) CAN Bus 2) AMS Wire1 3) PDS2 4) XPD cabling 5) Sub-detectors (need to prioritize) n) GTSN (Dallas) Critical Brackets: 1) vertical tubes on VC 2) Front panels 3) Balconies (info from Mockup?)
Possible Solutions (pending agreement internal to each person’s institute / Co.) a)Franck 4 CERN from February, need full funding for this time -need to guarantee maintenance time -% work time designated to AMS cabling for follow-up. To what %age (min 1-2 days a week supported by LAPP) a)Antonella: Contract with CGS 4 months, from Feb -need to guarantee maintenance time -% work time designated to AMS cabling for follow-up. To what %age Uses UG compatible with NASA model. Will need training period for new NX4 version and harnessing module. c) Serena Starting Now! Supported by INFN Perugia (?!) –learning CAD and harness program, Follow-up possible? To what %age? (will have to attend TVT-test starting end February-July but can support to a degree) d) Combined: Serena starts immediately with Franck joining February. Follow up? Who? (Franck can support 1-2days/week) What %age. (Serena? ) Need Big! Computer + CAD licenses Office in 892 RBxx double office for 4 engineers. Available!
Input Needed: List of cables (Xcel table) Front panel drawings – labeled. Or clarification!.. Ask Mike.. Or CGS web-site Updated detector models (and simplifying when necessary) Cables routed on mockup & photos (when needed) Fixation points (USS, crates, links, detectors, etc.) Cable properties Cross section (sleeves, MLI?), weight, bending radius Sticky tab properties (load rating) Plumbing routing (magnet, TTCS, UGBS, Zenith radiator,) (MLI) CAD Licenses
