| Abstract: | In order to make the BES ESC(Beijing Spectrometer End Cap Shower Counter) working in the SQS mode and get the energy resolution and energy linearity improved, the performance of detector working with the mixture gas composed of Ar, CO 2 and isobutane has been studied. Under different gas ratios of Ar, CO 2 and isobutane, a series of the detector characteristics, such as the plateau curve, the initial working voltage of SQS signal, etc., are tested carefully. In addition, the influence of the isobutane purity has also been tested, and a best mixture working gas for ESC has been found. ( |
