Abstract :
We show that adding CF4 to the standard Ar/CO2 gas mixture allows to substantially improve the time resolution of triple-GEM detectors.
s paper we discuss measurements of time resolution, discharge probability per incident charged particle and pad multiplicity of a triple-GEM detector with pad readout, with new gas mixtures with CF4 and isobutane.
s for detectors with GEM foil size of both 10×10 cm2 and 20×24 cm2 are presented.
