Signal propagation and spark mitigation in resistive strip read-outs

Abstract

MicroPattern Gaseous Detectors (MPGD) made of resistive strips are a promising technology for the protection against spark phenomena leading to discharges in the gaseous chamber. The reproduction of the signals and its propagation through the resistive foil is mandatory to better understand its behavior and optimize the key parameters which might depend on the application requirements. In this work a resistive-strip model and the charge diffusion through the resistive strip will be introduced. Different model parameters, such as the strip linear resistivity and capacitance, will be evaluated together with the advantages and/or disadvantages of this type of technology. © 2012 IOP Publishing Ltd and Sissa Medialab srl.
