Paper Abstract

We measured the average anisotropy of the primary charge cloud produced by photoelectron when an x-ray beam linearly polarized is absorbed on a Ne-DME gas mixture by using a micro-gap proportional counter. This average anisotropy is not present when an Fe55 unpolarized x-ray source is used. We discuss the results of our measurement in terms of performances of this detector as an x-ray polarimeter.
