Micropattern Gaseous Detectors opened a novel way for photon detection for RICH applications; mostly using hole-type amplifiers like GEM and ThickGEM in cascaded or hybrid structures. The main features are low ion backflow, high gain, and possibility for suppressing the MIP signal. This suppression can enhance the dynamic range, and allow for high gain operation, while using cost effective electronics. A ThickGEM and wire chamber based hybrid was constructed, and tested in particle beam as RICH detector. Systematic studies on the MIP suppression with the usage of ThickGEMs were carried out. The dependence on field configuration and the effective gain of the ThichGEM were measured and quantified.
