We report the results from characteristic study of a straw tube detector prototype using premixed gas of Argon and CO2 in 70/30 and 90/10 volume ratio. In this study the gain and the energy resolution are measured using Fe55 X-ray source. Same X-ray source is used to irradiate the straw and to collect the spectra. The main motivation of this work is to study the variation of the gain and energy resolution of the straw tube detector with X-ray rate per unit length in a laboratory for the first time. No accelerator or X-ray generator is used. The details of the test set-up, the method of measurement and the test results are presented in this paper.
