  1. Ecal and vacuum chamber design Unité mixte de recherche CNRS-IN2P3 Université Paris-Sud 1191406 Orsay cedex Tél. : +33 1 69 15 73 40 Fax : +33 1 69 15 64 70 http://ipnweb.in2p3.fr

  2. Support crystals Frame design 4 assembly 46 crystals frame on each bloc Top crystals block Steel sheet glued on aluminum frames Bottom crystals block 1 assembly 24 crystals frame on each bloc 1 assembly 13 crystals frame on each bloc

  3. Detail of Top assembly frame Reinforcement beam Screws for rigidity Positionning pins External Support parts Screws that link aluminum support plate and the crystals frames

  4. PCB and preamplifier mecanic design Cut view of crystals + PCB Mother board Preamplifier and its flexible kapton Connection board outlet Connection board Rails for pramplifiers sliding Connector for APD wires Copper plate and its cooling tube

  5. Cooling system Copper plate with tube d8xd6 Brass tubes d4 x d3.2 between vacuum chamber and crystals Copper plate and cooling tubes between crystals and electronic Aluminum plate with aluminum tubes in front of the crystals

  6. Cut view of the assembly The box iscomposed of 3 layers : 1 )Copper plates + tubes for cooling system 2 ) Foam for heatinginsulation 3 ) PVC +Kapton for Nitrogensealing(avoiddew point) Conventions of colors: Red =copper; pink=insulation foam; blue =PVC frame beije=pvc plates (except the chamber) ;dark grey = Aluminum )

  7. Cut view of the assembly Vacuum chamber Optic fibers Part for intermediate copper plate and PCB fixation (only top part represented) Sheet of Kapton glued on pvc frame for gaz sealing at the font of the Ecal and in front of the vacuum chamber to minimize the Gap

  8. Supporting and independant adjustment of Top and bottom Ecal 3 targets for survey on each bloc 4 support parts adjustable for each block Support Cable tray ? Cooling and gas lines ?

  9. Vacuum chamber Back flange Chamber Front flange welding Details to discuss with Mike Zarecky Aluminum honeycomb pillar
