EE and SE Installation

This document provides an overview of the installation process for the Ecal Endcap (EE) and PreShower Endcap (SE) components of the CMS experiment at CERN. It discusses the installation scenario, schedules, manpower requirements, and cost estimates. The SEs, which are donut-shaped disks weighing 2.5 tons, must be installed before the beampipe in June 2006, while the EE, consisting of two 12-ton Dees, can be installed afterward. The report also highlights the collaboration among engineers and physicists in the installation process.

  2. Introduction: • SE (preShower Endcap) • Each SE is a donut-shaped disk of 2.5 tons • SEs have to be installed before beampipe in ’06 according to V33 • SEs arrive fully tested at SX5 • Preliminary installation of SE on EE Dummies to debug • EE (Ecal Endcap) • Each EE consists of 2 Dees • Each Dee is a half-disk of 12 tons (incl. frame), installation • after beampipe possible • Dees arrive fully tested and in up-right position at SX5 after • test mounting at assembly area HE = HCAL Endcap, HF = HCAL Forward 11/9/2002 2 Wolfgang Funk - CERN CMS

  11. Schedule, Manpower and Cost Estimates (SE): • Dates: Jun. 06 (12 working days) for SE+ and SE- • Mechanical installation: 1day/SE • Electrical installation and testing: ~week/SE • Manpower: point 5 Support Team, technicians, engineers • and physicists from collaboration institutes (3+3) • (no hired manpower needed) • Installation tools: 2 frames and 1 lifting gear <40K • schematic drawings existing • SE table is part of EE platform • HF raisers (time to build up raisertower: 2h) 11/9/2002 11 Wolfgang Funk - CERN CMS

  12. Schedule, Manpower and Cost Estimates (SE)(2): • Services from patch panels onwards: cabling link person • cooling link person • 40 patch panels /SE • per patch panel: 2 LV cables, 1 HV cable, 1 DCS cable • inside cooled cable trays • cable trays used as well for EE services • 10 fiber cables/SE, 4 cooling pipes/SE • Manpower for cabling from CMS cabling team • Cabling already done in 2004/2005 11/9/2002 12 Wolfgang Funk - CERN CMS

  13. Schedule, Manpower and Cost Estimates (EE): • Dates: Jan. 07 (2 months) for EE+ and EE- • Mechanical, electrical installation including testing: 2 weeks/EE • ’’Flying’’ test system: (used for EB, as well) with cooling, HV, LV • and fibers connected to patch panels (2/Dee) • Manpower: point 5 Support Team, technicians, engineers • and physicists from collaboration institutes (3+3) • (no hired manpower needed) • Installation tools: 4 Dummy Dees: ~100K (study underway) • EE platform(s): (2X) 100K (drawings existing) • HF raisers, Airpads are standard CMS • If Dees are late: SE stays on Dummy EE, LHC shutdown period • (2 months summer 07) could be used to install • EE- or both (EE+, EE-) 11/9/2002 13 Wolfgang Funk - CERN CMS

  14. Schedule, Manpower and Cost Estimates (EE)(2): • Services from patch panels onwards: cabling link person • cooling link person • 4 patch panels /Dee • per patch panel: 1 cooling pipe, 34 LV cables, • 4 HV cables, 3 fiber cables, DCS cables • inside cooled cable trays • cable trays used as well for SE services • Manpower for cabling from CMS cabling team • Cabling already done in 2004/2005 11/9/2002 14 Wolfgang Funk - CERN CMS

  15. Conclusion: • Costs are accounted in costbook • Installation is using only point 5 Support Team and • institutional manpower (no hired manpower needed) • Contingency plan exists • Production drawings of installation tools have to be made • Start of tooling production 2003 after EDR • All tooling submitted for approval to TIS 11/9/2002 15 Wolfgang Funk - CERN CMS
