Acceleration of deuterons in a spherical ion diode with a laser-plasma anode

A physical model is proposed for a spherical pulsed ion diode with a laser ion source consisting of a plasma anode which varies in size while the accelerating voltage is applied. A study of this process was conducted using computer analysis of the nonlinear differential equations that are proposed in the article. From the results of the computer experiment, acceleration characteristics of the deuterons are established for similar diodes, and the effect of diode geometries, temporal and electrical characteristics on the energy spectra of the deuterons, the current pulse shape, and the deuteron acceleration charge are studied.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 2, pp. 67–71, February, 1988.In conclusion, the author expresses a deep gratitude to A.
