Study of light ions acceleration in a diode with a solid target and registration of nuclear proton-boron reaction products generated in the plasma diode

The results of proton fluxes registration and the nuclear reactions (p + 11B > 3α) they induce on boron-containing targets in a plasma diode pinch, generated by irradiation of the anode target with a relativistic electron beam, are presented. The dominance of protons as the fastest component of the explosive plasma fronts is observed, with energies exceeding those determined by the diode voltage. Alpha particles as products of nuclear reactions, are detected as emitted directly by the hot zone of the pinch when the anode target contains boron, as well as during the interaction of protons with the boron-containing screen behind the cathode, regardless of the anode target composition.
