Abstract
This article describes the design, construction, and performance testing of two Varian klystrons, model VK X-7864A, which replaced the aging and less efficient VA-949J klystrons in the X-band planetary radar transmitter on the Goldstone, California, 70-meter antenna. The project was carried out jointly by the Jet Propulsion Laboratory and Varian Associates. Output power was increased from 200 kW to 250 kW continuous wave per klystron, and full dc beam power is dissipated in the collector (it was not possible to operate the VA-949J klystrons without RF drive because of limited collector dissipation capability). Replacements were made with a minimum of transmitter modiffcations. The planetary radar transmitter is now operating successfully with these two klystrons.
