On the Possibility of Creating a Point-Like Neutron Source

We consider the possibility of creating a compact high-power neutron generator with a small emitting area (of the order of 100 μ m) and a neutron yield of 10 10 s −1 on the basis of a deuterium–deuterium fusion reaction (or 10 12 s −1 on the basis of a deuterium–tritium fusion reaction). The fusion...

Zusammenfassung:We consider the possibility of creating a compact high-power neutron generator with a small emitting area (of the order of 100 μ m) and a neutron yield of 10 10 s −1 on the basis of a deuterium–deuterium fusion reaction (or 10 12 s −1 on the basis of a deuterium–tritium fusion reaction). The fusion takes place under bombardment of a deuterium- (or tritium-) saturated target by a high-current (about 100 mA) focused deuterium ion beam with an energy of ~ 100 keV. The ion beam with total current at a level of hundreds of milliamperes and small emittance (less than 0.1 π·mm·mrad), which is crucial for sharp focusing, can be generated by a quasi-gas-dynamic ion source of a new generation created on the basis of a discharge in an open magnetic trap sustained by high-power electromagnetic radiation of the millimeter wavelength range under electron cyclotron resonance conditions. Simulations of the focusing system for the experimentally obtained ion beam show the possibility to create a deuterium ion beam with a transverse size of 200 μ m on the neutron-forming target. Prospects for using such a neutron source for neutron tomography are discussed.
