Significantly improved spatial uniformity of bremsstrahlung radiation, relative to a planar-anode diode, is obtained on the 3-MV, 150-kA HELIA accelerator when a B/sub theta/ lens diode is used to actively control the high-power electron beam at the exit of a coaxial, magnetically insulated transmission line. The advantage of this diode over other diodes which only passively control the beam is that better radiation uniformity for less beam loss is possible. Measurements taken on HELIA are shown to agree with theoretical expectations.
