Journal of Applied Physics, 118 (9) In present paper, an approach for high yield compact D-D neutron generator based on a high current gasdynamic electron cyclotron resonance ion source is suggested. Results on dense pulsed deuteron beam production with current up to 500 mA and current density . It is discussed that compact neutron generator with such characteristics could be perspective for a number of applications like boron neutron capture therapy, security systems based on neutron scanning, and neutronography.

New approach for a “point-like” neutron source creation based on sharp focusing of a high quality deuteron beam produced by high-current gasdynamic ECR ion source

“…Experimental studies of ion beam properties and search for optimal discharge conditions for high brightness beam formation were carried out at SMIS 37 experimental facility [6][7][8]. SMIS 37 provides gyrotron radiation at 37.5 GHz frequency with peak power up to 100 kW in 1.5 ms pulses for plasma heating.…”

“…A Faraday cup was placed right behind the puller electrode to measure the total beam current passing through the extractor. Emittance of the extracted beam (all species together) was measured with "pepper-pot" method, which has been successfully tested earlier at SMIS 37 [6][7][8].…”

“…A size of the neutron emitting area would be determined by the quality of the ion beam and the efficiency of the beam focusing system (ie, the minimum size of the bombardment area). This proposal is based on recent developments [6][7][8] of the unique high-current ion source. Such source utilize high-power gyrotron millimeter-wave radiation for plasma production in an open magnetic trap under conditions of electron cyclotron resonance (ECR).…”

Development of deuterium-loaded targets for D-D neutron generator based on high-current gasdynamic ECR ion source

“…They are called high-current gas-dynamic ECR sources. These devices are using powerful gyrotrons to heat the plasma and form deuterium ion beams with a density of 700 -1000 mA/cm 2 (absolute record for ion sources of any type) [6]. Ion beams with current up to 1 A and current density more than 1 A/cm2 were not available before for D-D generator, therefore there are no studies of neutron-generating target able to sustain up to 100 kW heat load which authors are aware of.…”

Измерения Эмиттанса Газодинамического Электронно-Циклотронного Резонансного Источника Ионов

“…При выборе параметров компактного источника нейтронов DARIA в качестве ориентира послужил исследовательский реактор BER-II в Берлинском центре материалов и энергии им. Гельмгольца (HZB) (Германия), который обеспечивает пучок нейтронов плотностью 2 [14][15][16][17][18]. Для разработки ускоряющего канала и определения конкурентоспособности импульсного ускорителя проведены измерения эмиттанса данного источника протонов методом " pepper-pot".…”
