Preliminary results indicate ion feedback levels in single GEM detectors.

The method is suitable for applications with low event rates or small drift volumes.

Abstract

Gaseous detectors are used in both low energy and high energy physics experiments. The present day gaseous detectors, i.e., the Micro-Pattern gaseous detectors (MPGD) are more efficient and fast. Gas Electron multiplier (GEM) is quite well know among the MPGD members. The MPGDs are also being used in other applications like tomography/imaging, moreover, recently, hybridization of two different kinds of MPGD is another emerging subject of R\&D. Ion feedback is an intrinsic drawback of the gaseous detectors. However, it is not a big issue where the event rate is not very high, or the drift volume is not too large. Here, we are showing a simple experimental technique to find the ion feedback of a single GEM foil. This can address the experiments/applications where a single GEM foil is employed.
