Abstract

The invention discloses a laser fusion neutron irradiation effect test device, which includes a collection module, the collection module is equipped with a first pipeline and a second pipeline extending outward, wherein the remote end of the second pipeline is connected with a sample for placement assembly, used to fix the sample, the far end of the first pipeline is connected with a detection head assembly, used to measure the neutron dose near the sample, the collection module is connected to the detection head assembly through a first optical fiber, and the collection module is connected to the detection head assembly The sample placement components are connected by a second optical fiber, and the first optical fiber and the second optical fiber are placed in the first pipeline and the second pipeline respectively. The beneficial effect of the invention is that it can prevent corresponding parts in the collection module from being irradiated by neutrons, so as to ensure the accuracy of neutron dose measurement and effect evaluation.

Description

technical field [0001] The invention belongs to the technical field of neutron detection, and in particular relates to a laser fusion neutron irradiation effect testing device. Background technique [0002] Neutron irradiation is an important method of equipment radiation resistance strengthening test. During the test of neutron irradiation effect, in order for the sample to receive a sufficient dose of neutron irradiation, it is necessary to place the sample closer to the neutron radiation source. s position. [0003] In order to measure the neutron radiation dose received by the sample, the existing technical means is to directly place the neutron detector near the sample to measure the neutrons. However, the neutron radiation intensity near the radiation source is very high, which strongly interferes with the electronic system of the neutron detector itself, resulting in a large error in the measurement of the neutron dose. At the same time, high-intensity neutron irrad...
