Sheet electron beam confinement for rectangular cross-section Cerenkov amplifiers

Design aspects of a 94 GHz extended interaction Klystron

“…However, recent theoretical and numerical studies [1,2] have shown that stable transport of sheet beams is possible in periodically cusped magnetic (PCM) fields. The use of an offset-pole PCM configuration has been shown analytically [3] to provide side-fields for 2-D focusing of the beam, and this has been recently verified with PIC code simulations. We will present further theoretical studies of sheet and multi-beam transport and discuss experimental measurements of an offset-pole PCM array which is currently being constructed.…”
