论文摘要
优化了重型离子NICA对撞机的多功能检测器的Shashlyk型电磁量热计（ECAL），可为能量和电子的精确空间和能量测量在大约40 MeV到2-3 GEV的能量范围内提供精确的空间和能量测量。为了处理来自Au-Au反应的高次级颗粒，ECAL具有细分分割，由38,400个细胞组成（“塔”）。考虑到大量的“塔”和时间限制，无法用横梁校准每个ECAL“塔”。在本文中，我们描述了用宇宙元音对ECAL进行一阶校准的策略。
Shashlyk-type electromagnetic calorimeter (ECal) of the Multi-Purpose Detector at heavy-ion NICA collider is optimized to provide precise spatial and energy measurements for photons and electrons in the energy range from about 40 MeV to 2-3 GeV. To deal with high multiplicity of secondary particles from Au-Au reactions, ECal has a fine segmentation and consists of 38,400 cells ("towers"). Given the big number of "towers" and the time constraint, it is not possible to calibrate every ECal "tower" with beam. In this paper, we describe the strategy of the first-order calibration of ECal with cosmic muons.
