Proportional Counter array (PCa) — a new concept and its realization

Abstract

In this study, we introduce a new structure of micro-pattern gaseous detector, named proportional counter array (PCa). The standard Printed Circuit Board (PCB) process, which is cost-effective and easy to scale up, is used to manufacture the PCa prototypes. Both simulation and experimental studies were performed to characterise the prototypes, which demonstrated promising performance in terms of gas gain, rate capability, and ion backflow suppression. The prospects of the PCa technology are also discussed.
