研究了pbf2晶体和三种不同类型的铅玻璃块对来自美因茨Microtron MAMI的14 mev束流的电子的探测器响应。首次确定了这些切伦科夫辐射体在10 - 14 MeV能量范围内的信号高度、信号宽度和响应的均匀性。为了补充光束测试，研究了材料的光学特性，特别是在近紫外和可见光谱中测量的透射率。测量的探测器响应也与能量损失、光产生、传输和探测的蒙特卡罗模拟进行了比较。这些切伦科夫辐射体被认为是低能量热计的活性材料，用于探测美因茨能量回收超导加速器MESA的束流堆后面的轻暗物质粒子反冲电子。
A study of the detector response of PbF 2 crystals and three different types of lead glass blocks to electrons from a 14-MeV beam of the Mainz Microtron MAMI is presented. For the first time, signal height, signal width, and homogeneity of the response of these Cherenkov radiators were determined for energies between 10 and 14 MeV. To complement the beam tests, optical properties of the materials, in particular measured transmittances in the near UV and visible spectrum, were studied. The measured detector responses were also compared to Monte Carlo simulations of energy-loss, light production, transport, and detection. These Cherenkov radiators are considered as active material of a low-energy calorimeter for the detection of light dark matter particles recoiling off electrons behind the beam-dump of the Mainz Energy Recovering Superconducting Accelerator MESA.
