Pulse matching techniques for the characterization of gas detectors

We have characterized the gas amplification in P-10 using both the current and the pulse matching techniques. The measurements have shown that the correction of the effect of the associated electronics time constants is necessary. By the use of the experimental setup, we achieve a resolution of 13.84% at 5.9 keV using Fe55 source in P-10. The measurement of the pulse time parameters has led to the determination of the positive carriers mobility in P-10, argon-CO2 (5%) and argon-isobutane (10%) gas mixtures. A good agreement is obtained between our results and those deduced from Charpak et al. measurements. (authors). 8 figs., 1 tab., 19 refs
