Beam Background and Detector Layout 4th Concept Collaboration Meeting FNAL 19-20 October 2006
The Issues • SiD’s VXD and Beam Pipe is optimized for 5 Tesla B field • Beam optics requires for the TPC rin > 20.5 cm
The angles involved VXD B (13°) VXD B (12°) TPC & BP (10°) DREAM (6.5°)
The Numbers Involved • Small exercise using eq. Motion of particle in B-Field
Would it be a Problem? • Much will depend on ILC parameters
USSC beam parameters • TPC • VXD Barrel • VXD Endcaps • Beam Pipe • DREAM • Generic (4Tesla)
It will be for High Luminosity colored dots is 10cm detector at r=1.5 cm for 3,4,5 Tesla • TPC • VXD Barrel • VXD Endcaps • Beam Pipe • DREAM • Generic (4Tesla)
Need a Simulation for B=3.5 Tesla • Need a full simulation • 3.5 tesla (for 4th Concept) • 5 Tesla (for our exchange program with FNAL) • Files available at SLAC (stdhep) • D. Barbareschi will do that
