Abstract :
A high power five-cavity gyroklystron amplifier operating at 28GHz is under development at KBSI. The amplifier consists of a high power magnetron-injection-gun (MIG), a hybrid coaxial input coupler, three idler cavities, an output cavity, and a beam collector. Numerical codes used in the amplifier design include large-signal non-linear codes for amplifier gain and efficiency calculations, a 3-D electromagnetic simulator (HFSS), a thermal analysis code (ANSYS), and an electron trajectory code (EGUN).
