SCIPP R&D on the International Linear Collider Detector DOE Site Visit June 8, 2006 Presenter: Bruce Schumm R&D Activity is increasing, with studies now on a number of fronts: Physics/machine studies for e - e - running (see Heusch) Billior-based calculation of tracking errors Detector resolution standards from physics simulation Reconstruction capabilities of all-silicon tracking Hardware proof-of-principle of low-noise silicon strip readout Summary of Activities Current Involvements (all part time) 4 senior physicists 1 post-doc (looking for a second) 8 undergraduate students (major contribution) 1 engineer and 2 technical staff 1 bored spouse of a Silicon Valley engineer. Leadership Roles Heusch is member of International Cooperation Committee Schumm is lead convener of North American Tracking Working Group Detector Resolution Standards from Selectron Production Participants: Senior Physicist Bruce Schumm Undergraduate Thesis Students Sharon Gerbode, Heath Holguin, Troy Lau *, Paul Moser, Adam Perlstein, Joseph Rose, Matthew Vegas Community Member (on hold before Grad School) Ayelet Lorberbaum * Recipient of two Undergraduate Research Awards; grad school at U. Michigan. Motivation To explore the effects of limited detector resolution on our ability to measure SUSY parameters in the forward region. SiD Tracker SPS1A at 1 TeV Selectrons vs. cos( ) Electrons vs. cos( ) Roughly of statistics above |cos( )| of 0.8, but The spectrum is weighted towards higher energy at high |cos( )|, so theres more information in the forward region than one might expect. Determine the selectron mass accuracy in both the central (0 < |cos |
