Investigating effects of gas humidity on electrical discharge formation in MPGDs
Micropattern gas detectors (MPGD) are a type of particle detectors used in many large high energy physics experiments (Atlas, CMS, Alice) given their easy scalability. MPGDs work by amplifying the primary ionisation signals generated by impeding charged particles as they traverse a gas volume. This amplification of primary electrons is achieved by using structures with micrometer scale patterns that are different for various types of MPGDs, which include Gas Electron Multipliers (GEMs) and Micro-MEsh Gaseous Structure (Micromegas). One of the limiting factors for the long term stable operation of MPGDs is the formation of electrical discharges inside the amplification structures. Due to this, there has been an extensive effort over the years to understand and to develop methods to mitigate these discharges. One of the remaining questions however is how the humidity (the water content) of the used gas mixture affects the formation of discharges in MPDS. The aim of this project is to conduct the first comprehensive studies investigating the correlation between gas humidity and MPGD discharge stability. For this task, a dedicated detector chamber will be used with modifications to the gas system which enables the precise control of the ambient humidity levels. This venture is a great entry point for anyone interested in particle detector hardware research and development. The achieved results of which might end up shaping the next generation of cutting edge high energy physics experiments
