Mechanisms affecting the speed and direction of vacuum arc cathode spots movement in a magnetic field
Based on the known experimental and theoretical data, a new model of the plasma jet, which emit by cathode spot (СS) along the magnetic field proposed. According to this model, the plasma jet contains an oppositely directed current of accelerated ions of the cathode material with an excess positive...

На основі відомих експериментальних і теоретичних даних запропонована нова модель плазмового струменя, який емітує катодні плями (КП) вздовж магнітного поля. Згідно цієї моделі він містить протилежно направлені струм прискорених іонів матеріалу катода з надлишковим позитивним зарядом і струм прискорених електронів з надлишковим негативним зарядом, між якими утворюється електричне поле поляризації плазмового струменя. На основі цієї моделі вперше виконані розрахунки основних параметрів плазмового струменя від зовнішніх параметрів магнітного поля, струму дуги та середнього зарядового стану іонів у плазмовому струмені. Вперше з’ясовані основні механізми, що впливають на швидкість і напрямок руху КП дуги по поверхні торця катода, що випаровується. 2023 Article Mechanisms affecting the speed and direction of vacuum arc cathode spots movement in a magnetic field / V.V.
