摘要:

预闪(PSh)探测器是DIRAC设置的一个组件。它是为了提高ππ和Kπ对测量中e-e ~+对本底的抑制效率而设计的。为了提高整体效率,一个新的双层结构的闪烁体预展探测器已实现在该地区的氮切伦科夫探测器已被缩短,引入新的探测器。新的Preshower-Cherenkov组合保证了动量区1-7 GeV/c的电子排斥效率优于99.9%。

英文摘要:

The Preshower (PSh) detector is a component of the DIRAC setup. It is designed to improve rejection efficiency of e-e+ pairs background in the ππ and Kπ pair measurement. To increase the overall efficiency, a new two-layer structure scintillator Preshower detector has been realized in the region where the Nitrogen Cherenkov detector has been shortened to introduce new detectors. The new Preshower-Cherenkov combination ensures the electron rejection efficiency better than 99.9% in momentum region 1-7 GeV/c.
