Abstract

The Solenoidal Tracker At RHIC-Silicon Vertex Tracker (STAR-SVT) is a three-barrel microvertex detector based upon silicon drift detector (SDD) technology. As designed for the STAR-SVT, (SDDs) are capable of providing unambiguous two-dimensional hit position measurements with resolutions on the order of 20 uμ in each coordinate. In addition, a high-resolution energy loss measurement in the three layers of the SVT enables good particle identification. We describe features of the design of the STAR-SVT SDDs and electronics that are motivated by such characteristics. We also detail the mechanical structure, assembly procedures, and performance characteristics of the completed device.
