The magnicon: a new RF power source for accelerators

The results obtained in the course of the magnicon creation and study, as well as the calculations and the development of the device, have shown that the magnicon´s capabilities are characterized by the following parameters: (1) a power of up to 5-10 MW in the CW mode (at U/sub 0/=200-300 kV) and up to 500-1000 MW in the pulse mode (at U/sub 0/=0.8-1.2 MV), (2) an efficiency of about 60-80% (depending on the power and frequency), (3) a wavelength range from 2-3 cm up to 0.5-1 m (the frequency decrease is limited by the size growth), (4) a high gain (K=30-60 dB), (5) a relatively narrow frequency band ( Delta omega / omega <0.5%), and (6) a high amplitude and phase stability. These characteristics point to a good outlook for magnicon application both in accelerators and in other areas of microwave power engineering. As to communication systems, the utilization of the magnicon will be reduced to cases when it is necessary to have higher power rather than a broad frequency band.<>
