论文摘要
作为粒子流概念的一部分，建议将未来的山脉量子器（DHCAL）数字辐射热量计（DHCAL）。尽管主要使用电阻板腔（RPC）进行研究，但重点是基于微图案气态检测器（MPGD）的采样元件的研究表明了潜在的优势。它们可以用环境友好的气体进行操作，并在较低的平均垫层质量上达到相似的检测效率。我们在这里总结了一个小型DHCAL原型的实验测试束结果，其中包含六个微羊皮（MM）和两个电阻板井（RPWell）采样元件，并与钢制吸水板交织在一起。在CERN/PS梁设备上使用2-6 GEV旋束进行了研究。该数据允许验证DHCAL的GEANT4仿真框架，并评估了基于RPWell的全尺度量热仪的预期Pion能量分辨率。 $ \fracσ{e [gev]} = \ frac {50.8 \％} {\ sqrt {
Digital Hadronic Calorimeters (DHCAL) were suggested for future Colliders as part of the particle-flow concept. Though studied mainly with Resistive Plate Chambers (RPC), studies focusing on Micro-Pattern Gaseous Detector (MPGD)-based sampling elements have shown the potential advantages; they can be operated with environmental friendly gases and reach similar detection efficiency at lower average pad-multiplicity. We summarize here the experimental test-beam results of a small-size DHCAL prototype, incorporating six Micromegas (MM) and two Resistive-Plate WELL (RPWELL) sampling elements, interlaced with steel-absorber plates. It was investigated with 2-6 GeV pion beam at the CERN/PS beam facility. The data permitted validating a GEANT4 simulation framework of a DHCAL, and evaluating the expected pion energy resolution of a full-scale RPWELL-based calorimeter. The pion energy resolution of $\fracσ{E[GeV]}=\frac{50.8\%}{\sqrt{E[GeV]}} \oplus 10.3\%$ derived expected with the RPWELL concept is competitive to that of glass RPC and MM sampling techniques.
