Direct measurement of the avalanche charge in a Resistive Plate Chambers detector
نویسندگان
چکیده
We performed a direct measurement of the avalanche charge with a 10 10 cm 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 SF6 in the gas mixture (C2H2F4/i-C4H10/SF6 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. r 2004 Elsevier B.V.

متن کاملResistive Plate Chambers in avalanche mode: a comparison between model predictions and experimental results1
In this paper a model simulating the main aspects of avalanche growth and signal development in Resistive Plate Chambers (RPCs) is presented. The model has been used to compute the performances, in particular, charge distribution and efficiency of singledoubleand multi-gap RPCs, and to compare them with the available experimental results. This model could be used to optimize the characteristics...
متن کاملDetailed models for timing and efficiency in resistive plate chambers
We discuss detailed models for detector physics processes in Resistive Plate Chambers, in particular including the effect of attachment on the avalanche statistics. In addition, we present analytic formulas for average charges and intrinsic RPC time resolution. Using a Monte Carlo simulation including all the steps from primary ionization to the front-end electronics we discuss the dependence o...
متن کاملSimulation of Space Charge Effects in Resistive Plate Chambers
Multigap resistive plate chambers [1] with 0.3-mm gas gaps operated in avalanche mode at atmospheric pressure have reached timing accuracies below 50 ps (standard deviation) with efficiencies above 99% [2]. The avalanches in high homogeneous electric fields of 100 kV/cm are strongly influenced by space charge effects which are the main topic of this paper. We extend a previously discussed Monte...

We present a simulation model suited to study efficiency, timing and pulse-height spectra of Resistive Plate Chambers. After discussing the details of primary ionisation, avalanche multiplication, signal induction and frontend electronics, we apply the model to timing RPCs with time resolution down to 50 ps and trigger RPCs with time resolution of about 1 ns: r 2003 Elsevier Science B.V.
