Abstract

The results of using the FLUKA package to calculate the radiation environment around building no. 1 of the Laboratory of High Energy Physics, which contains the ion injection systems, booster, and Nuclotron of the NICA complex in operation for the collider and for experiments with fixed targets, are presented. The calculation has been performed for the mode of ¹⁹⁷Au ion acceleration to an energy of 578 MeV/n The main dose-forming component of the radiation field around the building is neutrons of a wide energy range. Detailed models of an ion acceleration ring and the geometry of shields and building details are used in the calculation. The calculation results indicate that the adopted design decisions with the given rates of ion losses will ensure compliance with radiation-protection norms during the operation of the NICA booster.

预测NICA Booster周围的辐射环境

摘要

使用FLUKA软件包计算建筑物No.1周围辐射环境的结果。介绍了高能物理实验室的1个组件，其中包括离子注入系统，助推器和NICA配合物的Nuclotron，它们正在对撞机和具有固定目标的实验中运行。已针对¹⁹⁷模式执行了计算Au离子加速至578 MeV / n的能量建筑物周围辐射场的主要剂量形成成分是能量范围很广的中子。计算中使用了离子加速环的详细模型，屏蔽的几何形状和建筑物的细节。计算结果表明，在给定的离子损失率的前提下，采用的设计决策将确保在NICA助推器工作期间符合辐射防护规范。
