Abstract :
Analysis of a quadrupole focusing lattice for high-frequency TWT´s is presented. Single particle tracking is performed to determine the phase advance, with the eventual goal of determining the advantageous frequency regime for devices using this focusing method. This work is motivated by recent work which demonstrated an advantageous case for strong focusing employing a Halbach quadrupole lattice.
