Problems solved by technology

The energy range of these neutron sources is between 0.01 and 42 MeV. They have made important contributions to China's nuclear data research including China's own CENDL nuclear data evaluation database, but their energy is not continuous, and each accelerator can provide part neutron beams of energy fragments with low beam intensity

Abstract

The invention discloses a control system for charged particle detection spectrometer of white light neutron source. The control system of the present application comprises a local control system and aremote control system; the local control system comprises a motion control module, a vacuum monitoring module, a gas circuit voltage stabilizing module, a particle beam window, and a true air path component protection module; the remote control system is in signal connection with the local control system and used for remotely controlling the operation of the modules of the local control system. The control system of the present application can monitor the state of the vacuum target chamber in real time, and can realize the remote control of the sample changing device, the detector angle rotation mechanism and the vacuum air path system, and the solid foundation can be safely, stably and reliably operated for the vacuum target chamber. The EPICS PV released by the remote control system candirectly enter the voice alarm system and the historical database system of the CSNS accelerator central control room, so that convenient and reliable guarantee is provided for timely finding and processing the problems, performing post hoc analysis and equipment research and the like.

Description

technical field [0001] The present application relates to the field of neutron detection equipment, in particular to a control system for a white light neutron source charged particle detection spectrometer. Background technique [0002] The white light neutron source is an extremely useful tool for nuclear data measurement and research, which can provide key nuclear data for the design of new nuclear energy facilities, nuclear astrophysics research, basic physical science, and national defense technology. Nuclear data measurement research has been carried out in the world for nearly 80 years, and has gone through several stages of nuclear data measurement for single-energy point neutron sources, white-light neutron sources in resonance regions, and fast white-light neutron sources. Before the 1960s, low-energy accelerators were mainly used to produce monoenergetic neutrons with a certain intensity through the reactions of d-D, d-T, p-T and p-7Li to measure the neutron react...
