Design of a Compact Millimeter Wave Gyrotron

Compact gyrotron was supposed to be a promising continuous millimeter source for industrial applications. Bitter solenoid with transverse and axial cooling channels was designed in this paper. Through optimizing, uniformity length of this Bitter solenoid reaches 80mm with homogeneity 0.5% at magnetic field 1.1 tesla when inner warm bore 20mm and consumes 10.2kW power. And then, beam-wave simulation with designed magnet was adopted by CST Studio which predicts 400W output power at 30GHz when operating voltage and current 5kV and 0.5A.
