Design and development of an indirectly
heated solid cathode for a linear electron beam emitter assembly can be found
as following image. The solid cathode is made of tungsten with cathode shape,
called tungsten cathode. Thermionic electron beams emitted from a directly
heated strip shaped filament have been used to heat the cathode indirectly. The
temperature of the cathode, measured by a two color pyrometer, was raised to
250002K. The innovative design of the cathode and its holding mechanism
accommodates thermal expansion at high temperature, and prevents thermal
deformation of the cathode. The cathode is suitable for use in strip electron
beam gun and for laboratory experiments on melting and evaporation of
refractory materials.
