The operation of gas detectors is often limited by secondary effects, originating from
avalanche-induced photons and ions. Ion backflow is one of the effects limiting the operation …

In this study we investigate the stability limits of Micromegas detectors upon irradiation with
alpha particles. The results are obtained with meshes with different optical transparency and …

Ion backflow is one of the effects limiting the operation of a gaseous detector at high flux, by
giving rise to space charge which perturbs the electric field. The natural ability of bulk …

Micromegas detector is considered to be a promising candidate for a large variety of high-
rate experiments. Micromegas of various geometries have already been established as …

ABSTRACT A variety of sophisticated radiation detectors is used in laboratory and
fieldbased experiments related to particle physics, nuclear physics and related branches of …

The operation of gas detectors is often limited by secondary effects, originating from
avalanche-induced photons and ions. Ion backflow is one of the effects limiting the operation …

This thesis consists of two independent parts. In the first section, an automated system for
moving a radiation source for testing micromegas detectors was designed, assembled, and …

The micropattern gaseous detectors (MPGD) are fast radiation detectors capable of
operating in high-luminosity environment and offer high gain, good position and time …

Ion backflow is one of the effects limiting the operation of a gaseous detector at high flux, by
