We report a successful implementation of a three-dimensional wavelet-based solver for Poisson's equation with Dirichlet boundary conditions, optimized for use in particle-in-cell beam dynamics simulations. We explain how the new algorithm works and the advantages it brings to accelerator simulations. The solver is integrated into a full photoinjector-simulation code (Impact-T), and the code is then benchmarked by comparing its output against that of other codes (verification) and against laboratory measurements (validation). We also simulated the AES/JLab photoinjector using a suite of codes. This activity revealed certain performance limitations and their causes.
