To overcome the problem of bremsstrahlung radiation in Beam-target fusion, a combinatorial approach has been suggested by Tri-Alpha and Helion energy companies, this method is based on interpenetration of two oppositely directed plasmoids. Theoretical works represent that by creating and warming two accelerated head-on colliding plasmoids up to some kilo electron volts thermal energy which is low in comparison with that of required for thermonuclear fusion, net fusion gain is possible even with aneutronic fuels such as p-11B. In order to attain the necessary conditions of break-even by this method the accelerated plasmoids must have enough colliding velocities of the order of some thousands of kilometers per second (106 m/s) depending on the kind of fusion fuel. In addition, the plasmoids density must be between the inertial and magnetic fusion criteria.
