Description
The STAR experiment was primarily designed to detect signals of a possible phase
transition in nuclear matter. Its layout, typical for a collider experiment, contains
a large Time Projection Chamber (TPC) in a Solenoid Magnet, a set of four layers of
combined silicon strip and silicon drift detectors for secondary vertex
reconstruction plus other detectors. In this presentation, we will report on recent
global and individual detector element alignment as well as drift velocity
calibration work performed on this STAR inner silicon tracking system. We will show
how attention to details positively impacts the Physics capabilities of STAR and
explain the iterative procedure conducted to reach such result in low, medium and
high track density / detector occupancy.
