Synchrotron light sources operate with bunch repetition rates in the MHz
regime. The longitudinal and transverse beam dynamics of these electron
bunches can be investigated and characterized by experiments employing
linear array detectors. To improve the performance of modern beam
diagnostics and overcome the limitations of commercially available detectors,
we have at KIT developed KALYPSO, a detector system operating with an
unprecedented frame rate of up to 12 MHz. To facilitate the integration in
different experiments, a modular architecture has been utilized. Different
semiconductor microstrip sensors based on Si, InGaAs, PbS, and PbSe can be
connected to the custom-designed low noise front-end ASIC to optimize the
quantum efficiency at different photon energies, ranging from near-UV,
visible, and up to near-IR. The front-end electronics are integrated within a
heterogeneous DAQ consisting of FPGAs and GPUs, which allows the
implementation of real-time data processing. This detector is currently
installed at KARA, European XFEL, FLASH, Soleil, DELTA. In this contribution,
we present the detector architecture, the performance results, and the
