Abstract
A comparison is described between the 3-D simulation code ARACHNE and a recent 33.4 GHz collective PEL amplifier experiment at MIT. The experiment demonstrated power levels of 61 MW (= 27% efficiency) without recourse to tapered magnetic fields using a 750 keV/300 A electron beam with an axial energy spread of 1.5% propagating through a cylindrical drift tube in the presence of a helical wiggler [Bw ≤ 1.8 kG, λw = 3.18 cm] and a guide magnetic field [B0 ≤ 12 kG]. The maximum power was observed when the wiggler and guide fields were antiparallel. ARACHNE is in substantial agreement with the experiment and shows peak power levels of 60 MW.
