In the search for improved microwave communications systems, the electron beam devices which at present form the heart of such complexes are called upon to perform in more and more rigorous environmental conditions. There is a continuing demand for small er, lighter, more rugged packages. One aspect of this trend is the desire for a beam focussing means which does not inhibit the inherent ruggedness of the device. In this respect, electrostatic focussing offers some considerable advantages over the presently available magnetic systems in terms of mechanical and temperature stability.
