ABSTRACT:
An ignitron device is provided in which a permanent annular magnet at least partly surrounds the region between the ignitron anode and the surface of a mercury pool connected to the cathode terminal, the magnet being effective to create an axial magnetic field in the aforementioned region which tends to constrain the discharge arc of the device towards the center of the pool and away from the envelope walls of the device.
