Abstract
The STAR silicon strip detector (SSD) completes the three layers of the silicon vertex tracker (SVT) already installed inside the time projection chamber (TPC). This additional fourth layer provides two-dimensional hit position and energy loss measurements for charged particles, improving the STAR tracking performances and the extrapolation of the TPC tracks to the SVT hits. The design of the barrel is described; in particular the choice of the tape automated bonding (TAB) technique to connect the detectors to their front-end electronics (FEE). Several hardware aspects of the detector are presented like the power supply, the readout chain and the cooling system, as well as the production chain from the detection module to the barrel.
