Abstract

The work presented in this paper focuses on the first 10 years (2011–2020) of radiation test object (RTO) operations at the National Criticality Experiments Research Center. RTOs are subcritical configurations of special nuclear material that are built by hand. These configurations are utilized for benchmark experiments, detector testing/characterization, and training. An overview of the types of measurements used in RTO operations is given as well as a history of RTO operations at Los Alamos National Laboratory from 1944–2011.

核临界实验的新时代：NCERC 辐射测试对象运行的前 10 年

摘要

本文介绍的工作重点关注国家临界性实验研究中心辐射测试对象 (RTO) 运行的前 10 年（2011-2020 年）。RTO 是手工建造的特殊核材料的亚临界配置。这些配置用于基准实验、探测器测试/表征和培训。概述了 RTO 操作中使用的测量类型以及洛斯阿拉莫斯国家实验室从 1944 年到 2011 年的 RTO 操作历史。
