Description
The d+d reaction is very well suited for calibration due to the 2.45 MeV fast neutron reaction channel. Due to this circumstance, the d+d neutron generator is considered as one of the promising tools for calibrating low-background neutrino and dark matter detectors [1]. The current status of the development of a compact neutron generator is presented. The generator includes the elements of the Pierce electron gun, magnetic elements for effective ion generation and the target assembly at a positive potential. Unlike previous versions [2-5], the current version of the neutron generator allows obtaining a stable and controllable low neutron flux (100-1000 particles per second per full solid angle).
The current design of a compact neutron generator, a computer model of the electric field and ion flux are presented. The results of the ion current and neutron flux measurement under various conditions are discussed.
