Abstract: A CW microtron with a 500~MHz RF cavity is proposed for industrial applications. The machine is of a racetrack type. The acceleration energy and the beam power of a prototype machine are 5 MeV and 30 kW, respectively. The RF cavity is a conventional normal-conducting 2-cell cavity with coupling slots. The injection energy is 80 keV, and a 500 MHz CW gun is used. The bending magnets are divided into two subsections to adjust the acceleration phases of every turn. Beam tracking studies show that the longitudinal phase stable region is more than 20 degrees and the transverse beam stability can be obtained with fringe fields of the bending magnets and two QMs near the RF cavity.
