Abstract
To fix the design parameters for the Aerogel Cerenkov counters for the TASSO detector several test modules were investigated. They all were equipped with aerogel with a refractive index around 1.025. Direct unscattered light contributes with about 7 photoelectrons when collected by a mirror. In detectors with diffuse reflecting walls 3–18 photoelectrons were measured depending on the size of the system. With the 32 cells of the TASSO Cerenkov detector an efficiency of 4.1 ± 0.3 photoelectrons for relativistic cosmic particles were found.
