Studies of the effect of rate on gain for straw tube detector

TL;DR

This study investigates how rate, temperature, and pressure affect the gain and energy resolution of a straw tube detector using different gas mixtures, providing detailed experimental results and analysis.

Contribution

It presents experimental data on the effects of rate, temperature, and pressure on straw tube detector performance with specific gas mixtures.

Findings

Gain varies with rate per unit length.

Temperature and pressure influence energy resolution.

Performance characteristics depend on gas mixture ratios.

Abstract

Basic R & D have been carried out with one small straw tube detector prototype with premixed gas of Ar+CO2 in 70:30 and 90:10 ratio. The gain and the energy resolution are measured with Fe55 X-ray source. Effect of temperature and pressure on these parameters are measured. The variation of gain and energy resolution with rate per unit length are also measured. The details of the test set-up, the method of measurement and the test results are presented in this paper.
