  • Enhancement of ion beam charge states by electron vortices in a plasma optical device 
    Goncharov, A.; Maslov, V.; Brown, I. (Вопросы атомной науки и техники, 2005)
    We consider the possibility of enhancing the ionization charge states of beam ions by electron vortices excited in cylindrically symmetric plasma optical systems of finite length with crossed radial electric and longitudinal ...
  • Focusing of ion beams by permanent magnet plasma lens 
    Protsenko, I.; Goncharov, A.; Gorshkov, V.; Gubarev, S.; Litovko, I.; Brown, I. (Вопросы атомной науки и техники, 2002)
  • Influence of magnetic field strength on the focusing properties of a high-current plasma lens 
    Goncharov, A.A.; Gubarev, S.M.; Protsenko, I.M.; Brown, I. (Вопросы атомной науки и техники, 2000)
    We present results of experimental studies of the operation of the high-current wide-aperture plasma lens in the range of low magnetic fields. Investigations of focusing of copper and carbon ion beams with current up to ...
  • Plasma and ion beam surface modification at Lawrence Berkeley National Laboratory 
    Brown, I. (Вопросы атомной науки и техники, 2000)
    Surface processing by metal plasma and ion beams can be effected using the dense metal plasma formed in a vacuum arc discharge embodied either in a “metal plasma immersion” configuration or as a vacuum arc ion source. In ...
  • Surface modification of Nd-Fe-B based materials with pulsed helium plasma streams 
    Bovda, A.; Bovda, V.; Byrka, O.; Chebotarev, V.; Garkusha, I.; Matyushenko, N.; Tereshin, V.; Tortika, A.; Brown, I. (Вопросы атомной науки и техники, 2005)
    X-ray amorphous Nd₂Fe₂₃B₃ phase have been synthesized under the interaction of accelerated helium plasma with Nd₈Fe₈₇B₅ and Nd₄,₅Fe₇₇B₁₈,₅ alloys. Microstructure and composition of modified layer have been examined.
