Gamma ray transmission imaging detectors using a double gap resistive plate chamber
نویسندگان
چکیده
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 mm 2. RPC sensitivities for various gamma ray energies were evaluated by the GEANT-based simulations.

Study 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...
متن کاملCosmic ray test results on resistive plate chamber for the BESIII experiments
A cosmic ray test system has been built to fully qualify the resistive plate chambers for the MUON system of the BESIII experiment. The setup has been designed to measure detector’s performance and to verify the stability and reliability of the MUON system. The same electronics, similar readout method and data analysis for BESIII MUON system have been used for this station. With this station, t...
متن کاملCharacteristics 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...

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...
