- Description: The resistive plate chamber (RPC) is a very successful wireless gaseous detector which is able to give >98% efficiency and 1 ns response. The absence of wire technologies and the cheap material involvement makes the production costs very low and therefore it can be used to build very large area detectors. This study describes the performance of a single gap sensitive RPC for a photons detector. The aim of this study is to understand the behaviour of a single gas gap RPC, in particular with 2 and 3 mm thickness, and to observe their response estimation at relatively small detection areas. The simulation studies have been performed using the GEANT3 and GEANT4 Monte Carlo packages. Good agreement is obtained between the experimental and simulated results. © 2007 The Royal Swedish Academy of Sciences.

- Description: In order to investigate the neutron sensitivity we applied a realistic MC simulation based on GEANT3 code with MICAP and FLUKA interfaces for two different types of resistive plate chambers for CMS/LHC. In the present studies sensitivity calculations have been performed as a function of neutron energy in the range of 100 eV to 1 GeV. In the first setup using aluminum (GND+strips), the sensitivity for an isotropic neutron source was obtained to be Sn<9.04×10-3 at <100 MeV, while for the second setup using copper (GND+strips) sensitivity for the same source configuration is Sn<9.91×10-3 at <100MeV. Both the results are relative to an RPC in double-gap configuration with an isotropic neutron source. Additionally in these setups similar characteristics have been observed for parallel neutron source configuration. © 2005 Elsevier B.V. All rights reserved.

- Description: Resistive plate chambers (RPCs) have been chosen as a part of the muon trigger detectors in the CMS experiment. They are used both in the endcaps and in the barrel regions, and they have to work in an extreme radiation background. Test of glass-RPC detectors have been performed in order to investigate their performance in such situations. In the present work, the simulation response of glass-RPCs exposed to positrons/electrons is evaluated. As expected a lower sensitivity of glass-RPC with respect to the bakelite-RPC has been observed since the glass density is higher and therefore a lower fraction of electrons can reach the gas gap. The obtained results were applied to CMS/RPC endcap and barrel regions, and their respective sensitivities to those particles are reported together with hit rates. © 2007 Elsevier Ltd.

- Description: For more than 20 years nuclear physicists have used the GEANT code to simulate particle-matter interaction. In most recent version, GEANT4 is a toolkit for simulating the passage of particles though matter, which contains a complete range of functionality including tracking, geometry, physics models and hits. In this article, an attempt to use GEANT4 to model a double-gap resistive plate chamber (RPC) with its improved efficiency is presented. The efficiencies of the double-gap RPC have been evaluated as a function of gamma energy range 0.005-1000MeV. A comparison to available previous simulation package GEANT3 data is also performed. © 2006 Chin. Phys. Soc. and IOP Publishing Ltd.
