FEEDING SYSTEM OF A HIGH-FREQUENCY ACCELERATING CAVITIES OF THE NOVOSIBIRSK MICROTRON-RECOVERY UNIT FOR THE FEL. DIVIDER OF A HIGH CW POWER ON THE BASIS OF A RECTANGULAR WAVEGUIDE

Read more The article is devoted to the system of the Radio Frequency power transfer and distribution between accelerating cavities of the ERL for FEL of the Siberian center of SR and THz Radiation, SB RAS, Novosibirsk. The system of dividing is built on the basis of a rectangular waveguide, associated with each cavity of a coaxial line by the coaxial-to-waveguide adapter (CWA). It is shown that under a certain choice of waveguide sizes and CWA, the equivalent circuit of the CWA can be represented by a current source. The analysis of the properties of such a system has been carried out and shown its advantages. Also it is discussed the experimental results and the experience of the operation of the device. The article presents the basic design parameters of a waveguide divider 600 kW of continuous power, running at a frequency of 180.4 MHz.
