Abstract New accelerator-based photon sources require pixel detectors with fast readout rate and large dynamic range. When the development is focused on detecting soft x-ray single photons then low noise is another competing requirement of the detector. FLORA, conceived to exploit the high repetition rate operation at LCLS-II with focus on soft X-rays, is being developed to address these needs. It targets single photon sensitivity at 250 eV, a dynamic range of 104 photons per pixel per frame, a continuous readout of more than 40k frames per second (kfps), and a pixel of 50 um × 50 um. We present and discuss technical choices and test results of the first prototypes.
