Free-running virtual cathode microwave sources characteristically exhibit bandwidths in a single pulse of tens of percent, which makes them unsuitable for many applications such as power sources for phased array antennas and microwave linear accelerators.
As peak powers in excess of 10 GW have been reported, attention has begun to focus on techniques for producing a more frequency- and phase-stable virtual cathode source.
The evolution of virtual cathode based high-power microwave-source technology has been directed primarily toward achieving higher peak- power levels. International Nuclear Information System (INIS)įazio, M.V. High-power microwave generation from a frequency-stabilized virtual cathode source (3) We demonstrated that phase locking of sources together in large numbers is a feasible technology and showed the generation of multigigawatt S-band radiation in an array of relativistic magnetrons. This device has been used both on our single pulse machines, CAMEL and CAMEL X, and the repetitive system CLIA. (2) We demonstrated an L band relativistic magnetron. Since the conclusion of this contract such specifications have also been demonstrated for the relativistic klystron under Ballistic Missile Defense Organization funding. This was done for the relativistic magnetron. The requirements of this program were met in the following way: (1) We demonstrated that a compact linear induction accelerator can drive HPM sources at repetition rates in excess of 100 HZ at peak microwave powers of a GW.
In this project the HPM application was power beaming. The requirements of this project have been to: (1) improve and expand the sources available in the facility for testing purposes and (2) perform specific tasks under direction of the Defense Nuclear Agency about the applications of high power microwaves (HPM).
