LINEAR ACCELERATOR BASED ON PARALLEL COUPLED ACCELERATING STRUCTURE

Linear accelerator based on parallel coupled accelerating structure and RF-controlled electron gun is developed and produced. The structure consists of five accelerating cavities. The RF power feeding of accelerating cavities is provided by common exciting cavity which is performed from rectangular waveguide loaded by reactive pins. Operating frequency is 2450 MHz. RF-controlled Electron gun is made on the basis of RF triode. Linear accelerator was tested with different working regimes. The obtained results are following: • energy is up to 4 MeV, accelerating current is up to 300 mA with pulse duration of 2.5 ns on the half of the width, • energy is up to 2.5 MeV, accelerating current is up to 100 mA with pulse duration of 5 μs, • energy is up to 2.5 MeV, accelerating current is up to 120 mA with pulse duration of 5 μs and beam capture of 100%. The descriptions of the accelerator elements are given in the report. The features of the parallel coupled accelerating structure are discussed. The results of the measuring accelerator’s parameters are presented.
