He made numerous contributions to the generation of high-power atomic beams: he developed working prototypes of both diagnostic and heating atomic beams based on charge-exchange of positive ions; he also created efficient high-current sources of negative ions employing surface conversion, suitable for high-energy neutral beam injectors.
However, his most influential results lie in the area of magnetic mirror physics, where his paper "A Thermonuclear Trap with Double Mirrors" (Fizika Plazmy, v. 3, July-August 1976) initiated research on tandem mirrors in the USSR and contributed to an international effort in this area. He, with his colleagues Eduard Kruglyakov and Dmitri Ryutov, made numerous contributions to the promise of tandem mirrors, in particular, for advanced fusion fuels. In 2005, he published a review of research on ambipolar traps and tandem mirrors in the journal Physics-Uspekhi, v. 48, No. 11, 2005.
