摘要：
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 500mA and current density up to 750 mA/cm(2) are demonstrated. Neutron yield from D2O and TiD2 targets was measured in case of its bombardment by pulsed 300mA D+ beam with 45 keV energy. Neutron yield density at target surface of 10(9) s(-1) cm(-2) was detected with a system of two He-3 proportional counters. Estimations based on obtained experimental results show that neutron yield from a high quality TiD2 target bombarded by D+ beam demonstrated in present work accelerated to 100 keV could reach 6 x 10(10) s(-1) cm(-2). 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.
