The performance of micro-strip gas counters (MSGCs) has been studied with gas mixtures of neon and dimethylether. The setup consisted of two 10 × 10cm2 MSGC detectors placed in a cosmic ray hodoscope made of twelve drift chambers. Measurements are presented for the collected charge and the detection efficiency. A Monte Carlo simulation has been used to verify our understanding of the efficiency measurements. The simulation has also allowed to estimate the transverse diffusion coefficient of the electrons in the gas and to predict the spatial resolution of the detectors.
