A vacuum photoelectric detector (monitor) (VPD) designed for plasma tomography, megnetohydrodynamics monitoring, and imaging with the help of thermal x-ray radiation on the ITER facility is described. Laboratory experiments demonstrate that VPD has high sensitivity to thermal x rays and low sensitivity to hard gamma rays and neutrons. The results of tests of a prototype of this monitor on a (60)Co source of gamma rays, on nuclear reactor and its calibration using radiation from an x-ray tube, and tests of its serviceability on the T-10 facility are presented.
介绍了一种为ITER装置上的等离子体层析成像、磁流体动力学监测以及借助热X射线辐射进行成像而设计的真空光电探测器（监测器）（VPD）。实验室实验表明，VPD对热X射线具有高灵敏度，而对硬伽马射线和中子具有低灵敏度。给出了该监测器原型在（60）Co伽马射线源、核反应堆上的测试结果及其利用X射线管辐射进行的校准，以及在T - 10装置上的可用性测试结果。
