Abstract

The invention discloses a neutron source, and the neutron source comprises an ion source, a low-energy transmission segment, an RFQ accelerator, a high-energy transmission segment, a radio frequency power source, a target station device, and a control system. The ion source is used for generating ions. The low-energy transmission segment is used for adjusting an ion beam. The RFQ accelerator is used for increasing the speed of the ion beam, so as to enable the energy of each ion to be within the range from 0.1MeV to 10MeV. The high-energy transmission segment is used for adjusting the ion beam after speed increase. The radio frequency power source is used for providing a radio frequency signal for the RFQ accelerator. The target station device is used for generating neutrons and leading the neutrons out. The control system is used for controlling the ion source, the low-energy transmission segment, the RFQ accelerator, the high-energy transmission segment, and the target station device. The neutron source can employ the independent RFQ accelerator, is small in size, is small in occupied space, is high in neutron yield, and is convenient for production and installation.

Description

technical field [0001] The invention belongs to the field of neutron production, in particular to a neutron source. Background technique [0002] The Radio Frequency Quadrupole (RFQ) accelerator was first proposed in 1970 by Kapuchinsky and Tepriakov, scientists of the Institute of High Energy Physics of the former Soviet Union. Focusing and longitudinal acceleration, because of its strong beam current, good quality, small size, easy to use and suitable for directly accelerating various ions from the ion source to the energy region of several MeV per nucleus, it is widely used in various accelerators Injectors, ion implanters, strong neutron sources, etc. [0003] In the prior art, the RFQ accelerator is generally applied to the neutron source in combination with the electron cyclotron or other components. The structure is relatively complicated, which is not conducive to production and installation. At present, a separate RFQ accelerator is applied to the neutron source T...
