Studies on the Optimal Working Point for Micromegas Detectors with Two-Dimensional Readouts — •Laura Wehner, Tai-Hua Lin, Chrysostomos Valderanis, and Matthias Schott — Johannes Gutenberg-Universität Mainz ,Germany
A 10×10 cm2 resistive Micromegas (MICRO MEsh GAseous Structure) detector with two-dimensional readout system consisting of 360 stripes per axis and 4 stripes per millimeter density has recently been tested in Mainz.
Measurements were performed under a variety of operating conditions, different Ar/CO2 gas mixtures, working pressure and working voltage using cosmic muons and a variable energy x-ray source as probes. We report on the performance of the detector under these operating conditions and we discuss the optimal operating point.
