Tracking Group Summary

Bruce `Lefty’ SchummUC Santa Cruz

Arlington Linear Collider Workshop

January 9-11, 2003

Since Santa CruzA number of new groups have entered the scene

11 proposals to NSF/DOE (1 via ADR program)

Three 90-minute phone meetings• Focus on simulation (11/6/02)• Focus on gaseous tracking (11/26/02)• Focus on solid-state tracking (12/12/02)

(Slides at http://scipp.ucsc.edu/~schumm/lctrack)

Poised to ramp up effort when funding becomes available

Simulation Effort

Goals of simulation subgroup:

• Develop requirements and specifications via the study of characteristic processes• Explore performance characteristics of proposed options, including realistic backgrounds and track densities• Help to delineate forward tracking options (pixels, strips, straws, etc.)• Explore tracking/calorimetry interfacing issues, including energy-flow, cal-assisted tracking, etc.

Simulation Groups

University of Oklahoma (Strauss, DOE pending):Forward tracking simulation

SLAC (Graf, NA):Simulation framework, forward tracking

Michigan (Riles/Yang, NSF pending):Tracking specs from central SUSY

Santa Cruz (Schumm, NA):Tracking specs from forward SUSY

Cornell (Peterson; NSF pending ):TPC tracking enhancement

Simulation Groups (cont’d)

University of South Carolina (Purohit, DOE pending): Axial-only central tracking

Louisiana Tech (Sawyer/Forest; DOE pending)Implementation of GEM tracking system

Hampton University (Baker; NSF pending): Rates/occupancies in forward region

Established near-term goals for simulation groups in ad-hoc noon meeting on Friday

Summary

Chicago/Santa Cruz initiatives have drawn substantialnew interest in R&D program

Some efforts await funding; all but one in attendance here at Arlington; all have begun to lay groundwork

Guiding principle: basic `proof of principle’ R&D through2005 (Design Manual?)

Looking forward to international tracking review March 31;re-asses/confirm R&D priorities at that point
