ABSTRACT
For several reasons Gas Ionization Chambers have proven their enormous versatility in experiments where heavy ions have to be detected. The detector design can easily be adapted to the experimental problem. It is possible to build detectors with very large sensitive areas. Extremely thin energy loss detectors can be built, as well as detectors which record all the kinematical quantities (E,dE,t,x,y) of a heavy reaction product. Using sampling ADC systems gas detectors can be provided which are able to measure several particles simultaneously. The first results of the Multiple Sampling Ionization Chamber (MUSIC), a new large area (1×2m2) detector measuring the charge of relativistic heavy ions, are presented.
