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.

Garfield++ simulations of single GEM detectors show that reducing pitch from 140 to 60 micrometers increases effective gain and improves position resolution while lowering electron transparency.
