  • Abstract
    Summary form only given. We present the circuit design of a 263 GHz Traveling Wave Tube (TWT) amplifier for use in Dynamic Nuclear Polarization (DNP) enhanced Nuclear Magnetic Resonance (NMR). The circuit design achieves a linear gain of 36 dB and output power > 50 W. This work describes the design of the interaction circuit for optimal interaction with a 20 kV, 125 mA elliptical beam using 3D electromagnetic Finite Element Method (FEM) and Particle-in-Cell (PIC) solvers.
