Current Challenges and Perspectives in Resistive Gaseous Detectors: a manifesto from RPC 2012.

Abstract

ABSTRACT:Resistive gaseous detectors can be broadly defined as a sub-type of gaseous detectors that are operated in conditions where virtually no field lines exist that connect any two metallic electrodes sitting at different potential. For most practical purposes, this condition can be operationally realized as 'no gas gap being delimited by two metallic electrodes' [1]. Since early 70's, Resistive Plate Chambers (RPCs) are the most successful implementation of this idea, that leads to fully spark-protected gaseous detectors, with solid state -like reliability at working fields beyond 100kV/cm, yet enjoying the general characteristics of gaseous detectors in terms of flexibility, optimization and customization. We present a summary of the status of the field of resistive gaseous detectors as discussed in a dedicated closing session that took place during the XI Workshop for Resistive Plate Chambers and Related Detectors held in Frascati, and especially we review the perspectives and ambitions of the community towards the XII Workshop to be held in Beijing in year 2014.

The use of multi-gap resistive plate chambers for in-beam PET in proton and carbon ion therapy

“…In particular, resistive plate chambers (RPC) have been studied. Though typically not used for gamma detection, RPCs are enticing for a PET application because of their excellent timing resolution for tracking charged particles, and because they are very cheap to produce in large surface areas [7]. …”

A microscopic Monte Carlo approach to modeling of Resistive Plate Chambers

“…Thus cross sections cannot be easily modified, compared or presented. The questions associated with the reliability of cross sections for electron scattering in RPC's gases were already raised in case of C 2 H 2 F 4 [17], which is the main component in gas mixtures for RPCs operated in avalanche mode. As will be shown, the final results that describe the RPC performance may differ considerably depending on the cross sections used.…”

“…Here the avalanche fluctuations and the RPC performance characteristics emerge naturally from the stochastic character of electron collisions and are determined exclusively by the cross sections for electron scattering. Such an approach based on MAGBOLTZ was used for the calculation of gas gain fluctuations [18] but still, no such attempts in RPC modeling were published [17].…”
