“…Neutrons were generated through D−D-reaction with the yield of fast neutrons (2.5 MeV) 1.2 • 10 10 s −1 at the beam current 50 mA and energy 75 keV in pulsed mode with pulse width of about 1 ms [26]. This neutron generator is considered not only for BNCT applications [22,27], but also for neutron tomography [28][29][30]26].…”

The results of the ion source of the neutron generator upgrade, which makes it possible to operate in a CW mode, are presented. A magnetic trap consisting of permanent magnets (NdFeB) was developed. A 3-electrode extraction system equipped with a magnetic lens was used to extract the deuterium ion beam. Calculations are made for the formation of a deuterium ion beam with a current over 500 mA and an energy of 100 keV with practically no losses in the extraction system. Keywords: extraction system, magnetic trap, neutron generator, ion beam.

“…In particular, up to 500 mA of proton and deuteron beams with the normalized RMS emittance lower than 0.1 π •mm•mrad were demonstrated. Furthermore, experiments in [10] showed the possibility of a point-like neutron source creation with the use of such ion beams, yielding the neutron flux of 10 10 s −1 . This paper continues experiments described in [10] and presents results of investigation on a sharp focusing of the ion beam with magnetic lens, its comparison this numerical simulations and development of a more effective focusing systems.…”

The paper presents recent results of a "point-like" neutron source development based on a D-D fusion in a D-loaded target caused by its bombardment with a sharply focused deuterium ion beam. These developments are undergoing at the Institute of Applied Physics of Russian Academy of Sciences in order to study a possibility to create an effective and compact device for fast-neutron radiography. Last experiments with a beam produced by a gasdynamic high-current ECR ion source and its focusing with magnetic lens demonstrated that 60 mA of deuterium ions may be constricted to a transversal size of ∼ 1 mm at the focal plane. With a purpose to improve this result in terms of the beam current and its size a combined electrostatic and magnetic focusing system is proposed and analysed. It is shown that combined system may enhance the total beam current and reduce its footprint down to 0.13 mm. All numerical analysis was performed using the IBSimu code.

This paper presents a study of plasma flux characteristics flowing out from the gas-dynamic mirror trap along the magnetic field lines to a metal wall. The main feature of the current work is that the effect of ion acceleration by ambipolar potential is considered in the expander region. The developed model also takes into account a possibility of transition from the collisional expansion of electron flow in the vicinity of the magnetic plug to the collisionless regime. The developed model allows calculation of the ambipolar potential profile and plasma characteristics in the expander region.
