Abstract :
The multi-cell proportional chambers in the backing calorimeter of the ZEUS experiment at the HERA storage ring are supplied with an Ar/CO2 gas mixture by an open gas system. Flow proportional counters with built-in 55Fe sources are used as gas system monitoring detectors. The results of the measurements of the aging effects of the gas-monitoring counters are presented.
