Abstract
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 e qual to 16.5 degrees and to suppress atomic events. It consists of a s cintillator plate and nine concentric scintillator rings with decreasi ng diameters. Each ring covers a polar angular range of Delta theta ap proximate to 1.85 degrees and is realized by two half-rings with separ ate light readout. The optimized shape of the rings and the light guid es was found through simulations with the Monte Carlo program SIMLIGHT .
