Parametric Study on The Improvement of The Beam Energy Gain of The Fantron-I Cavity

The industrial electron accelerator named FANTRON-I whose merits are its low fabrication cost, high reliability and easy maintainability is under development at Physico technology laboratory, KAPRA (Korea Accelerator and Plasma Research Association). To make the simplified machine, it is required to optimise the beam energy gain and beam transport efficiency. The beam energy gain is dependent on the several factors, such as geometry (loop area, coupler diameter, shape, direction of the coupler area, etc.) of RF power input antenna. In addition, RF cavity also should be tuned to match the impedance between cavity and RF generator. As a result, various parameters which have effects on the machine performance should be surveyed for the optimisation through computations and experiments. In this paper, parametric study results on the optimisation of the beam energy gain of FANTRON-I cavity are presented.
