Since the 70-ies, the gaseous particle detectors are mandatory elements of the large high energy physics detector systems. With the advent of the microstructure detectors, the developments took a new pace in the last two decades, allowing higher rate capability and radiation tolerance. The key is the micrometer-scale components, such as tiny holes in a Gaseous Electron Multiplier (GEM), which optimize the electron transport. The purpose of the research within the scope of the present PhD project is generic development, diagnostic methodology and understanding the fundamental gaseous processes in these systems. Modern technologies, such as high density circuit production and 3D printing, can improve both the new and the classical structures.

A particular application is the so called Muography, which utilizes high energy muons, created in the high atmosphere, to map the density of large scale objects. Due to the limited rate, the main challenge is the construction of large size detectors. The research project aims to design, build and install such systems, and from the analized data, contribute to the optimization of the next generation Muography imagers. Applications include imaging active volcanos (in Japan particularly),  or underground research for mining and speleology.
