论文摘要

Calice半数雄性量热仪（SDHCAL）是Calice Collaptoration开发的高颗粒性热量计的家族中的第一个技术原型，以配备未来Lepton Colleders的实验。 SDHCAL是使用不锈钢作为吸收剂和玻璃电阻板室（GRPC）作为敏感培养基的采样量热仪。 GRPC的读数为1〜cm $ \ times $ 1〜cm的拾音垫，这些拾音垫合并到多阈值电子产品。该原型在2015年在CERN PS和SPS梁上都暴露于强子梁中，允许对SDHCAL的测试在较大的能量范围内从3〜GEV到80〜GEV。在介绍了用于选择数据的HADRON并拒绝MUON和电子污染的方法之后，我们介绍了我们应用于从光束线收集的数据的能量重建方法，并讨论了SDHCAL的响应线性和能量分辨率。在两个光束线中获得的结果证实了2012年在SPS梁线中使用相同原型收集的数据观察到的出色SDHCAL性能。它们还显示了在不同的光束条件和不同时间段内SDHCAL的稳定性。

The CALICE Semi-Digital Hadronic CALorimeter (SDHCAL) is the first technological prototype in a family of high-granularity calorimeters developed by the CALICE Collaboration to equip the experiments of future lepton colliders. The SDHCAL is a sampling calorimeter using stainless steel for absorber and Glass Resistive Plate Chambers (GRPC) as a sensitive medium. The GRPC are read out by 1~cm $\times$ 1~cm pickup pads combined to a multi-threshold electronics. The prototype was exposed to hadron beams in both the CERN PS and the SPS beamlines in 2015 allowing the test of the SDHCAL in a large energy range from 3~GeV to 80~GeV. After introducing the method used to select the hadrons of our data and reject the muon and electron contamination, we present the energy reconstruction approach that we apply to the data collected from both beamlines and we discuss the response linearity and the energy resolution of the SDHCAL. The results obtained in the two beamlines confirm the excellent SDHCAL performance observed with the data collected with the same prototype in the SPS beamline in 2012. They also show the stability of the SDHCAL in different beam conditions and different time periods.
