โœฆ Synopsis

We performed a direct measurement of the avalanche charge with a 10 ร‚ 10 cm 2 prototype resistive plate chambers with a 0.2 cm gas gap. We studied its behaviour with respect to the high voltage and its dependence on the presence of the SF 6 in the gas mixture (C 2 H 2 F 4 /i-C 4 H 10 /SF 6 in the ratio 95/4/1 and 96/4/0). The measurements showed a double exponential behaviour of the average avalanche charge with respect to the high voltage. A comparison with other results has been discussed.

A big advance in resistive plate chamber technology happened in 1996 with the advent of the multigap resistive plate chamber (MRPC). The MRPC allows us to easily construct detectors with many small gas gaps and thus we obtain good timing together with high detection efficiency. Using this technology
