Abstract

The current results of operation of the first CM1 cryogenic moderator in the direction of neutron beams 7, 8, 10, and 11 at the power of IBR-2 with a new cryogenic system are presented in the paper. A new cryogenic system allowed to reduce the temperature of the working mixture in the chamber of the CM1 moderator when operating at a reactor power of 2 MW by 10 K to ~22–23 K which made possible to acquire gain in the intensity of cold neutrons ~15–20%.

摘要

本文介绍了使用新的低温系统在IBR-2的作用下，第一台CM1低温减速器在中子束7、8、10和11的方向上运行的当前结果。当在2 MW的反应堆功率下运行10 K至〜22-23 K时，新的低温系统可以降低CM1减速器腔室内工作混合物的温度，这使得获得冷中子强度成为可能〜15–20％。
