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 کاملLET Monitoring Using Liquid Ionization Chambers
Relative biological effectiveness (RBE) is an important quantity in planning particle beam cancer therapy. In general, the RBE describes the biological effectiveness of a given primary beam with respect to a reference photon irradiation. RBE varies not only for different primary beams but also with depth in the target for a given beam modality. It is not a quantity that easily lends itself to m...
متن کاملIonization of liquid argon by a particles
From an analysis of electron pulses in liquid argon produced by a particles the average energy required to form an ion pair is evaluated, assurmng JaEk’s theory of columnar recombination is valid. The mean value of 26.0 ev found in this way agrees well with the corresponding value of 26.4 ev for a particles m argon gas. Application of Jaffk’s theory to the liquid state is discussed, and from th...
