“…In particular, when forming a beam of negative ions, it is possible to decrease the power of the co-extracted electron beam [4]. The use of the new approach makes it possible to unleash the potential of those facilities, where the plasma emission ability exceeds the capability of the extraction system [5].…”

“…This article is devoted to the experimental verification of the proposals formed in [1]. The SMIS 37 [5] pulsed facility was chosen as an experimental base. It is a high-current ion source based on plasma of an electron cyclotron resonance (ECR) discharge, sustained by the radiation of a gyrotron with a frequency of 37.5 GHz and a power of up to 100 kW in a magnetic trap of a simple mirror configuration.…”

We report on a successful test of a new method for intense ion beam formation using an extraction with inhomogeneous electric field. Its key feature is a special shape of the extraction electrodes providing a higher rate of ion acceleration. It is applicable to any ion source type and could be used to improve performance of a wide range of plasma devices. The proof of concept was carried out using a high-current electron-cyclotron resonance ion source SMIS 37. High efficiency of the new extraction and proton beam formation with a record current density of up to 1.1 A cm −2 was demonstrated.

“…One of the promising sources of protons is an ECR source with a quasi-gasdynamic regime of plasma confinement [11,12]. In such a facility, it is possible to maintain plasma with unique parameters: a density of more than 10 13 cm −3 (which is more than an order of magnitude higher than the plasma density in traditional sources) and an electron temperature of 50 − 100 eV, which is an optimal value for hydrogen dissociation and ionization.…”

In the quasi-gasdynamic high-current ion source described in this work, the plasma is sustained by high-power millimeter-wave radiation under the electron cyclotron resonance (ECR) condition. In such facilities, it is possible to achieve high volumetric energy input of up to 250 W/cm 3 and obtain pure proton beams with a minimum amount of impurities and molecular ions. Experiments conducted on the GISMO facility demonstrated the possibility of a proton beam formation with a current of 50 mA and an extremely high (99.9%) content of atomic ions.

“…A compact pulsed neutron generator [22] based on the ECR of ion source SMIS (Simple Mirror Ion Source) with a gasdynamic confinement mode [23] was previously developed at the Institute of Applied Physics of the Russian Academy of Sciences. Plasma is created using microwave radiation of the gyrotron [24,25] at a frequency of 37.5 GHz with a power of up to 100 kW and a pulse width of 1 ms.…”

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.
