摘要：

The performance of a telescope of Micromegas detectors has been studied in a pion beam at the CERN PS. With a gas filling of CF4 and 20% isobutane and with a strip pitch of 100 mum an accuracy of 14 +/- 3 mum on the spatial resolution has been measured at normal incidence. A simulation demonstrates that the resolution is limited by the size of the holes of the mesh of the detector and could be reduced to 11 mum in the same conditions with smaller holes. Even further improvement down to 8.5 mum is feasible for the same gas with an optimized 75 mum strip pitch. (C) 2001 Elsevier Science B.V. All rights reserved.
