The output circuit according to the invention comprises a ring-shaped cavity formed by a waveguide with a section in the shape of an H that is turned back on itself. The output circuit comprises holes for coupling with the output cavity, these holes being evenly arranged on its internal cylindrical wall, and the said output circuit has at least one hole for coupling with a using circuit, set on its external cylindrical wall.

Output circuit for klystron and klystron with an output circuit of this

The invention relates to multiple beam lasertrons. The n (n: integer greater than 1) electron beams of the lasertron are obtained from the same laser beam from which n secondary laser beams are extracted, by occultation, which are deflected respectively towards the n photocathodes of the lasertron.

Multiple beam lasertron

The dimensions of the resonant cavities of the multiple-beam klystron are determined in such a way as to enable functioning in the TM.sub.0n mode (n=a whole number greater than 1) and drift tubes relative to the beams go through the klystron cavities at places where the electrical field, in the cavities, is at its maximum value. This embodiment results in high-powered klystrons capable at working at high frequencies.
