Abstract

Summary Form only given, as follows. Temporally and spatially resolved beam electron current density measurements at the anode foil of the Recirculating Linear Accelerator (RLA) 1.5-MV, 15-kA isolated-Blumlein injector have been made using a beam aperture technique. This method derives the beam current density radial profile from the magnitude of the beam current exiting from a range-thick aperture of varying radius centered on the beam axis and placed in contact with the downstream side of the planar anode foil. Successful application of this diagnostic requires axisymmetric beams having good shot-to-shot reproducibility. Experimental and simulation results have been compared.<>
