KALYPSO is a novel detector operating at frame rates up to 10 MHz developed and tested at the KIT synchrotron light source and its storage ring KARA. This detector can consist of a Si, InGaAs, PbS or PbSe line array sensor with spectral sensitivity from 350 nm to 5000 nm. Such a wide spectral sensitivity for Si is obtained by applying an anti-reflection coating optimized for these wavelengths as well as the modular capability of the detector to employ sensors with different spectral sensitivities. The unprecedented frame rate of this detector is achieved by a custom-designed ASIC readout. FPGA-readout architecture enables continuous data acquisition and real-time data processing. Such a detector has various applications in the fields of beam diagnostics and spectral analysis and is currently employed at various synchrotron facilities to study the longitudinal profile and energy spread of the electron beam, tuning of free-electron lasers, and in characterizing laser spectrum. This contribution will present an overview of results from the mentioned applications.
