Abstract
In a thyratron gas discharge device, magnetic material is located coaxially with the anode to produce a magnetic field between the anode and cathode which is substantially parallel to a discharge established between them. This causes electrons emitted from the cathode to have longer path lengths than would otherwise be the case and so the ionization density within the device is increased. This improved this operating characteristics of the thyratron and results in greater utilization of the cathode.
