Neutron Generator Based on a Plasma Source with Gyrotron Heating

A new type of ECR ion sources - a gasdynamic ECR ion source was developed recently at the Institute of Applied Physics (IAP RAS, Nizhniy Novgorod, Russia). Such devices use powerful millimeter wave radiation of modern gyrotrons to produce plasma with parameters suitable for extremely high current ion beam production. The major part of previous experiments had been carried out in a pulsed mode. A new experimental facility named GISMO (Gasdynamic Ion Source for Multipurpose Operation) is under construction at the IAP RAS to develop a continuous working gasdynamic ion source. Future source will utilize 28 and 37.5 GHz / 10 - 20 kW gyrotron radiation for plasma heating. In 2013 the authors suggested an approach for high yield compact D-D neutron generator based on a high current gasdynamic ECR ion source. The GISMO facility should become a prototype of the intense neutron source suitable for boron neutron capture therapy.
