Detailed knowledge of particle beam properties is of great importance to understand and push the performance of existing and next generation particle accelerators. We recently proposed a new phase space tomography method to reconstruct the full 5-dimensional phase space, i.e., the charge density distribution in all three spatial directions and the two transverse momenta. This method is enabled by the PolariX TDS that allows for streaking of the beam at various angles. In this talk, the method as well as its experimental demonstration at the FLASHForward facility at DESY is presented. This includes the reconstruction of the full 5-dimensional phase space distribution of an electron bunch, the use of this measured phase space to create a particle distribution for highly-realistic simulations, and the extraction of the 4D slice emittance. Furthermore, an overview of the PolariX activities at the ARES linac will be given.
