多用途探测器 (MPD) 旨在研究 NICA 加速器综合体（俄罗斯杜布纳）的 √sNN=4–11 GeV 重离子碰撞中形成的热而致密的重子物质。 MPD 光谱仪的大型电磁量热仪 (ECal) 将为 |η| 中心赝快度区域中的光子和电子提供精确的空间和能量测量。 < 1.2。 ECal 的 Shashlyk 型采样结构针对约 40 MeV 至 2-3 GeV 的光子能量范围进行了优化。热量计的精细分割和投影几何形状允许处理来自 Au-Au 反应的大量二次粒子。在本文中，我们报告了 ECal 的设计、施工状态和预期参数。
The Multi-Purpose Detector (MPD) is designed to study a hot and dense baryonic matter formed in heavy-ion collisions at √sNN=4–11 GeV at the NICA accelerator complex (Dubna, Russia). A large-sized electromagnetic calorimeter (ECal) of the MPD spectrometer will provide precise spatial and energy measurements for photons and electrons in the central pseudorapidity region of |η| < 1.2. The Shashlyk-type sampling structure of the ECal is optimized for the photons energy range from about 40 MeV to 2–3 GeV . Fine segmentation and projective geometry of the calorimeter allow dealing with a high multiplicity of secondary particles from Au-Au reactions. In this paper, we report on a design, a construction status and expected parameters of the ECal.
