Abstract
DIADYN, a low energy laboratory equipment, is used to realize non-destructive diagnosis and beam dynamics for low energy electron beams. Typically, DIADYN is operated below 30 keV beam energy. Here we concentrate on results obtained during recent experiments, conducted at 32 keV beam energy, in a high energy mode of the DIADYN installation. The outcome of the beam diagnosis, realized by the modified three gradient method (MTGM), emphasizes the need to take into account the root-mean-square beam radius. For the beam dynamics, the image cross-over should be located behind the target plane, in order to obtain a good agreement between computed and measured beam radii.
