摘要：

We report on the recent test results of a MICROMEGAS detector in terms of position resolution, time resolution and efficiency. With a. Ar+CO(2) (10%) gas mixture and a strip pitch of 200 mu m an accuracy of 80 mu m in sigma on the position has been measured. The time resolution is better than 20 ns and a cosmic ray detection efficiency of 94% was obtained. A Monte Carlo simulation indicates that transverse diffusion, gain fluctuation and electronic noise limit the position resolution.
