Abstract

The 60-ton cylindrical electromagnetic calorimeter of the MPD facility of the NICA project with a diameter of 3.45 m and a length of 6 m under construction is assembled from 50 half-sectors, each containing 768 “Shashlik” towers of different sizes and different spatial orientations. The paper proposes methods for calibrating half-sector towers using cosmic muons passing both along and across the axes of the towers. The results of testing these methods on the first manufactured half-sector are presented.

利用宇宙射线μ介子校准 MPD/NICA 电磁量热计半截面的方法

正在建设中的日本核研究机构项目 MPD 设施的 60 吨圆柱形电磁量热计直径为 3.45 米，长 6 米，由 50 个半截面组装而成，每个半截面包含 768 个不同尺寸和不同空间方向的 "沙什利克 "塔。论文提出了利用宇宙μ介子沿塔轴线和跨塔轴线穿过来校准半截塔的方法。本文介绍了在第一个制造的半扇区上测试这些方法的结果。

期刊介绍： The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
