Description

PolariX transverse deflection structures (TDS) are installed at different accelerators at DESY and PSI to enable advanced characterization of the particle beams for applications like free-electron lasers, beam-driven plasma acceleration, or advanced acceleration R&D projects. The variable streaking angle of PolariX - a differentiating capability of this TDS - allows us to apply a variety of tomographic methods for beam characterization. These methods provide insight into the behavior of particle beams by reconstructing their phase space in multiple dimensions, revealing information that would otherwise be inaccessible. In this contribution, we present an overview of the high-dimensional beam reconstructions obtained experimentally at DESY and PSI. Furthermore, we show our latest developments of the applied tomographic methods including a significant improvement in measurement speed - an important step towards regular usability.
