GEANT4 code for Simulation of neutrons for a double- gap Resistive Plate Chamber
نویسنده
چکیده
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 Monte Carlo code to watch a double-gap Resistive Plate Chamber's (RPC) response to neutrons is presented. The simulation calculations of the double-gap RPC have been evaluated as a function of neutron energy in the range 1 × 10 MeV-10 GeV. For an isotropic neutron source using GEANT4 standard Electromagnetic Process MC code, sensitivity, sn < 2.547 × 10 at < 1 GeV by double-gap RPC has been observed. For the same neutron source with GEANT4 Low Electromagnetic Process MC code double-gap RPC sensitivity, sn < 2.557 × 10 at < 1 GeV has been measured. Similar characteristics of the RPC detector have been observed for parallel neutron source configuration. In addition, a comparison of the current GEANT4 double-gap RPC detector neutron simulation results with the GEANT3, and with the available experimental results is performed.

Characteristics of a double gap resistive plate chamber for the endcap region of CMS/LHC: data vs. simulation in avalanche mode
We present the detailed analysis of the time and charge signals of a prototype double gap resistive plate chamber for the endcap region of the compact muon solenoid detector at CERN LHC. We demonstrate that the operating highvoltage plateau can be extended at least up to 400V with the present design. The simple avalanche multiplication model can reproduce the experimental charge spectra reasona...

This study proposes a method to estimate RBE of fast neutrons using Monte Carlo simulations. This approach is based on the combination of an atomic resolution DNA geometrical model and Monte Carlo simulations for tracking particles. Atomic positions were extracted from the Protein Data Bank. The GEANT4 code was used for tracking the secondary particles generated by fast neutrons during their in...

In this paper we report a feasibility study of the gamma ray transmission imaging using a double gap resistive plate chamber. The detector consists of two layers of 2 mm resistive plate chamber (RPC) gaps with two-dimensional read-out strips of 10 mm pitch. Gamma ray transmission images for objects inside a cabinet, using a 10 mCi 137 Cs isotope, were obtained with a pixel resolution of 5 Â 5 m...

متن کاملStudy on the operational conditions of a double-gap resistive plate chamber for the CMS
We present the results from cosmic ray tests on the forward Resistive Plate Chamber (RPC) for the CMS. Double-gap prototype RPC were built and tested in the Korea Detector Laboratory (KODEL). We found that addition of SF 6 and water vapor to the tetra#uorethane-based gas mixture was required for the long-term stable operation of RPC. E$ciency, time resolution as well as cross-talk behavior of t...
