Способ повышения ресурса самонакаливаемого полого катода в сильноточном разряде в аксиально-симметричном магнитном поле постоянных кольцевых магнитов, отличающийся тем, что с помощью постоянных кольцевых магнитов с аксиальной намагниченностью создают резко неоднородное магнитное поле с инверсией направления продольной, составляющей поля, максимум которой располагают в плоскости кромки самонакаливаемого полого катода, что приводит к локализации разряда в области максимума магнитного поля и преимущественной эрозии кромки самонакаливаемого полого катода, по мере износа которой самонакаливаемый полый катод и постоянные магниты перемещают таким образом, чтобы максимум магнитного поля постоянно находился в области кромки самонакаливаемого полого катода.A method of increasing the life of a self-heated hollow cathode in a high-current discharge in an axially symmetric magnetic field of permanent ring magnets, characterized in that using permanent ring magnets with axial magnetization they create a sharply inhomogeneous magnetic field with an inversion of the direction of the longitudinal component of the field, the maximum of which is located in the plane of the edge self-heated hollow cathode, which leads to localization of the discharge in the region of the maximum magnetic field and predominant erosion of the edge of the self ivaemogo hollow cathode, wherein at least the wear samonakalivaemy hollow cathode and the permanent magnets is moved in such a way that the maximum magnetic field was constant in the edge area samonakalivaemogo hollow cathode.
