Experimental study of cathode spot motion and burning voltage of low-current vacuum arc in magnetic field

This experimental study dealt with cathode spot (CS) motion and the burning voltage of a low-current vacuum arc with electrodes of HCOF Cu and with a composition of CuCr30, subjected to a magnetic field. Arcs with current of I/spl ap/30 A burned in axial and transverse fields as well as with the ind...
