| Summary: | Title screen The paper presents the results of an experimental study of accumulation of copper macroparticles (MP) on a negatively biased substrate immersed in DC vacuum arc plasma. The influence of normal and tangential magnetic fields and high-frequency short-pulsed negative bias was investigated. The joint application of a tangential magnetic field and high frequency short-pulsed negative bias provides an effect of MP multifold suppression. With a tangential magnetic field strength of 175 Gs and repetitively pulsed bias (7 μs, 105 p.p.s., −2 kV), total suppression efficiency is 250-fold after 6 min of ion-plasma treatment. For macroparticles with the diameter of less or N1 μm, the efficiency is 3000-fold or 70-fold, respectively. In comparison with an axisymmetric vacuum-arc plasma source, the application of a steered arc ensures a 10-fold reduction in MP density on a substrate immersed in copper vacuum-arc plasma. The possibility of ion implantation using low-energy high-frequency short-pulse plasma immersion by implementing DC vacuum arc plasma is discussed.
