Low Gain Avalanche Detector (LGAD) technology has been used to design and construct prototypes of time-zero detector for experiments utilizing proton and pion beams with High Acceptance Di-Electron Spectrometer (HADES) at GSI Darmstadt, Germany. LGAD properties have been studied with proton beams at the COoler SYnchrotron facility in Jülich, Germany. We have demonstrated that systems based on a prototype LGAD operated at room temperature and equipped with leading-edge discriminators reach a time precision below 50 ps. The application in the HADES, experimental conditions, as well as the test results obtained with proton beams are presented.

低增益雪崩探测器用于HADES反应时间（T $$ _ 0 $$ 0）探测器升级

低增益雪崩探测器（LGAD）技术已被用于设计和构造零时探测器的原型，用于在德国GSI达姆施塔特（DSI）的高接受度双电子光谱​​仪（HADES）的情况下利用质子和介子束进行实验。LGAD的性质已在德国Jülich的COoler SYnchrotron设施中用质子束进行了研究。我们已经证明，基于LGAD原型的系统在室温下运行并配备了先进的鉴别器，其时间精度低于50 ps。介绍了在HADES中的应用，实验条件以及质子束获得的测试结果。
