At Eindhoven University of Technology several closely related projects aim at the production of ultra-short high-brightness electron bunches. An overview of these efforts is given, with emphasis on micrometer precise rf-photogun manufacture and three dimensional compression of uniformly filled (waterbag) electron bunches.

Partial GPT simulations results on the benchmark problem are presented. All parameters are used 'as-is', and no further scans or optimizations are done in order to get a perfect match. The photo-excitation laser image has been used to define the initial particle distribution. This makes it a 3D problem, and therefore the 3D multigrid space-charge model is applied. Different spot sizes for x and y are observed with a near-perfect match compared to the measurements. Simulated emittance values on the other hand are observed to be higher compared to the measurements.
