| Popis: |
The big tracking detector Time Projection Chamber (TPC) being constructed for the STAR experiment at RHIC requires an accurate calibration system to provide precision in crack reconstruction. The calibration system under construction uses a novel design of small mirror bundles to create /spl sim/500 thin laser beams. These beams simulate straight charge particles tracks in the TPC volume. The new approach is significantly simpler than the traditional ones, and provides a higher TPC coverage at a reduced cost. Results of test measurements and the system design will be presented. |
