摘要：

The STAR-detector was built as one component of a 4 pi-detector setup for the test of the Gerasimov-Drell-Hearn sum rule, The STAR-detector will be employed to determine charged hadronic particle rates at small forward angles 1.7 degrees less than or equal to theta less than or equal to 16.5 degrees and to suppress atomic events. It consists of a scintillator plate and nine concentric scintillator rings with decreasing diameters. Each ring covers a polar angular range of Delta theta approximate to 1.85 degrees and is realized by two half-rings with separate light readout. The optimized shape of the rings and the light guides was found through simulations with the Monte Carlo program SIMLIGHT.
