Space Charge Effects in Resistive Plate Chambers
We extend an existing one dimensional simulation model for avalanche mode RPCs by the inclusion of diffusion and space charge effects. We investigate the influence of space charge on charge spectra, signal rise time, time resolution and charge-to-time correlation. We present a 1.5-dimensional model, which allows fast simulation of events and a two dimensional model that is slower but allows to ...
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...
متن کاملSpace charge effects and induced signals in resistive plate chambers
Using special integral representations of the solution for the static electric field of a point charge in a three layer geometry with different permittivities, we calculate the effect of the space charge on the avalanche in the gas gap of an RPC. A detailed Monte Carlo simulation was developed which allows calculation of the actual charge spectrum. Results of this simulation are presented, usin...
متن کاملResistive Plate Chambers in ATLAS
The ATLAS first level muon trigger is based, in the rapidity region ( v ( 5 1.05, on fast and finely segmented gaseous detectors, Resistive Plate Chambers (RPCs) . A prototype of a small scale RPC trigger tower has been assembled and tested. We present results on efficiency, time resolution, cluster size and collected charge. The detectors, filled with a non-flammable and environment-safe gas m...
متن کاملInduced signals in resistive plate chambers
We derive theorems for induced signals on electrodes embedded in a medium with a position and frequencydependent permittivity eð~x; sÞ and conductivity sð~x; sÞ that are connected with arbitrary discrete elements. The problem is treated using the quasi-static approximation of Maxwell’s equations for weakly conducting media. The induced signals can be derived by time-dependent weighting fields a...
