7/15/11IBL IST G&S Integration2 Beam Pipe Al Shield is part of Pixel Faraday Cage. Figure is from LHC-VC1-ES The Aluminum foil is our responsibility to connect and reference to our purposes. To avoid adding extra shielding, Pixel and IBL G&S need to be integrated.

Connection Tasks Create Faraday cage from IST and Beam pipe Al foil. How do we connect the beam pipe foil to the IST shield skin? Additional connections at same area, both ends: a)14 cooling tubes b)14 Data cable shields c)14 Power cable shields d)Pixel end plate e)Single earthing tie, one end 7/15/11IBL IST G&S Integration4
IST G&S Questions a)How thick should the IST Copper/Kapton mesh be (copper equivalent thickness)? b)How do we connect the 5 IST sections, so that they support the Faraday cage conductivity (low RF impedance)? c)What are the envelope requirements at the joints and the ends? d)Closer to the IST ends are the cross-section material constraints loose enough to use continuous Kapton sheets, unetched? e)How do we make RF connections at the ends f)Can the IST end seal be integrated with these electrical connection tasks. 7/15/11IBL IST G&S Integration5
