Abstract

AbstractStudies of cathode strip chamber longevity, comparing Ar+CO$_2$ 2 gas mixtures with fractions of 5%, 2%, and 0% CF$_4$ 4 , were performed using several small cathode strip prototype chambers. In each trial, a localized source of radiation was used to irradiate up to an accumulated charge of about 300 mC/cm. Additionally, longevity of a uniformly irradiated prototype operating with 2% CF$_4$ 4 was studied at the CERN Gamma Irradiation Facility GIF++. Post-hoc analysis of the chamber electrodes using spectroscopy techniques was also done.
