A 250-KW CW X-band klystron

摘要

This paper describes the VA-949AM klystron amplifier which has produced 250 kw of CW power at frequencies near 7.8 GHz. This tube was designed in particular to be used by the Lincoln Laboratory of M.I.T. at the Haystack antenna site. Because the tube is mounted on the antenna, small size and light weight are important. The mechanical and electrical characteristics are described which show a total weight of the tube and its electromagnet of only 500 lb. For 250 kw of output power the beam requirements are 54 KVdc and 11 amperes.
