Abstract
The design of a 340GHz two-beam folded waveguide (FW) traveling-wave amplifier with >4 W of power over with the input power of 20mW is presented. The amplifier is driven by two electron guns (70mA×2, 14.9kV) and 1T magnetic field. The design is performed by CST Particle Studio. Particle-in-cell (PIC) simulations were carried out to predict and optimize the performance of the folded waveguide TWT.
