论文摘要
过渡辐射(TR)在高能物理学的粒子鉴定中起着重要作用,其特征为能量校准提供了可行的能量校准方法,最高10 TEV,这对于宇宙射线中的暗物质搜索非常有意义。在过渡辐射检测器(TRD)中,TR信号叠加到被入射电荷颗粒引起的电离能量损失信号上。为了使TR信号以显着的方式从电离能量损失的背景中脱颖而出,我们优化了辐射器和检测器。我们设计了一个针对最大TR光子产率优化的常规散热器的新原型,并与侧面TRD结合使用,该原型应提高TR的检测效率。我们在ConseilEuropéenpour la recherchenucléaire(CERN)的侧面TRD进行了测试束实验,发现实验数据与仿真结果一致。
Transition Radiation (TR) plays an important role in particle identification in high-energy physics and its characteristics provide a feasible method of energy calibration in the energy range up to 10 TeV, which is of interest for dark matter searches in cosmic rays. In a Transition Radiation Detector (TRD), the TR signal is superimposed onto the ionization energy loss signal induced by incident charged particles. In order to make the TR signal stand out from the background of ionization energy loss in a significant way, we optimized both the radiators and the detector. We have designed a new prototype of regular radiator optimized for a maximal TR photon yield, combined with the Side-On TRD which is supposed to improve the detection efficiency of TR. We started a test beam experiment with the Side-On TRD at Conseil Européen pour la Recherche Nucléaire (CERN), and found that the experimental data is consistent with the simulation results.
