Description
Budker Institute of Nuclear Physics in worldwide collaboration develops a project of a 14 MeV neutron source for fusion material studies and other applications [1,2]. The projected neutron source of plasma type is based on the gas dynamic trap (GDT), which is a special magnetic mirror system for plasma confinement [3]. Essential progress in plasma parameters was performed in recent experiments at the GDT facility in the Budker Institute, which is a hydrogen (deuterium) prototype of the source. Stable confinement of hot-ion plasmas with the relative pressure exceeding 0.5 was demonstrated. In these experiments, the density of fast deuterons with the mean energy of 10 keV, accumulated due to injection of powerful atomic beams, reached 5.0E19 per cubic metre. The electron temperature was increased up to 1 keV in the regime with additional electron cyclotron resonance heating (ECRH) of a moderate power [4]. These achievements shift the projects of a GDT-based neutron source on a higher level of competitive ability and make possible today to construct a source with reasonable parameters, suitable for materials testing.
The report presents a recent progress in experimental studies and status of numerical simulations of the mirror based fusion neutron source and its possible applications including a fusion material test facility and a fusion-fission hybrid system.
Current research activity in the Budker Intitute is supported by the Russian Scientific Foundation Grant №14-50-00080.
