Description
Next-generation accelerators, such as those employing plasma or laser wakefield acceleration techniques, demand precise characterization of the beam's properties, making accurate measurement of the five-dimensional (5D) phase space distribution essential. To meet this need, a novel transverse deflecting structure with adjustable polarization, known as the Polarizable X-band Transverse Deflector (PolariX TDS), has been developed through a collaboration between CERN, PSI, and DESY. By using this device, researchers at DESY have implemented a new tomographic algorithm capable of reconstructing the full 5D phase space of the electron beam. The PolariX TDS allows for beam streaking in a selected transverse direction by adjusting the polarization of the field inside the structure. When combined with a quadrupole scan, this functionality allows for complete 5D phase space reconstruction. This contribution presents measurements carried out at the Athos soft X-ray beamline of SwissFEL (PSI), showing the preparatory studies performed to apply this method at the Athos soft X-ray beamline at SwissFEL as well as showing first preliminary results towards the reconstruction of the 5D phase space under two different electron beam settings.
