Resistive 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...

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 ...

Induced 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...

Observation of light from resistive plate chambers

Electrically induced signals and light emissions from Restrictive Plate Chamber (RPC) are simultaneously measured using a glass RPC with transparent high-voltage planes, operating in the streamer mode. With one exception, good correspondence is seen in between the electrical and optical signals in every aspect: signal shapes, pulse heights, timing and afterpulses. The one exception is a possibl...
