Abstract

We present a new microstrip gas chamber design and a detailed experimental study of the effect of drift gap on its performance. The chamber has the provision to vary the drift gap in situ which enables one to carry out the performance study without altering the other set operating parameters such as gas pressure, anode voltage, and drift voltage. The effect of drift gap on detector gain and energy resolution is discussed here. The importance of optimization of drift gap is highlighted. The maximum gain obtained with P10 $(Ar90\%{+}CH_410\%)$ gas is $\sim750$ and the best resolution achieved is $\sim19\%$ for 5.9 keV x rays.
