Abstract—

A passive neutron dosemeter (PND) for high-energy accelerators is described. The slide of the DVGN-01 personal dosemeter, which is placed at the center of a polyethylene moderator, is used as a thermal-neutron detector. The moderator includes a lead insert, which increases the sensitivity of the dosemeter to high-energy neutrons, and a cadmium filter. Optimization calculations of the dosemeter design parameters have been performed with respect to the energy dependence of the response in the range from the thermal energy to 1 GeV. The results of the calculations are in good agreement with the experimental data obtained in low-energy neutron reference fields. Comparative measurements using the PND and a low-energy passive dosemeter have been performed in the neutron fields outside the shield of the 70-GeV U-70 proton accelerator at the Institute for High Energy Physics.

用于高能加速器的无源中子剂量计

摘要-

描述了一种用于高能加速器的无源中子剂量仪（PND）。DVGN-01个人剂量计的玻片位于聚乙烯减速器的中央，用作热中子探测器。减速器包括一个铅芯和一个镉过滤器，铅芯增加了剂量计对高能中子的灵敏度。已针对从热能到1 GeV范围内响应的能量依赖性进行了剂量计设计参数的优化计算。计算结果与在低能中子参考场中获得的实验数据高度吻合。
