Abstract: The crossed-field switch device has electrodes, and particularly an outer cathode electrode which in its main body has sufficient mechanical strength to serve as the device envelope and has an interior coating of a refractory material to resist sputtering. The method of producing the electrodes includes sputtering, when the anode is positioned within the cathode in normal device assembly.
