Abstract

The STAR experiment at RHIC uses high resolution Silicon Vertex Tracker and Silicon Strip Detector for track reconstruction in concert with Time Projection Chamber. The considerable benefits of using high resolution detectors in track reconstruction could be fully utilized only after accurate calibration and alignment. SVT sensors are silicon drift detectors. To obtain good resolution in drift direction the drift time to drift coordinate relationship is needed. The calibration procedure for drift detectors and alignment strategy are discussed and results are presented.
