Description
Detectors suitable for high repetition rate imaging and spectroscopy as well as for single photon detection are a key prerequisite for high sensitivity, transient EUV & soft X-ray absorption experiments. For this purpose existing CCD-based technologies first were compared to a new approach based on novel XUV/X-ray sensitive (scientific) CMOS sensors which recently have become commercially available.
To allow for the detection of single photons at lower energies it is necessary to extend the photon shot-noise-limited regime of the detector towards the lowest possible levels, in particular for those events generating only very few or even single electron-hole pairs. Therefore an existing camera hardware platform currently is revised and optimized for the integration of a variety of new CMOS-type sensors.
An overview of the progress and current road-map of the ongoing hardware redesign is given, including readout electronics, cooling system and overall mechanical design concepts. The envisaged performance characteristics of the camera as well as the planned key firmware and software functionalities are presented and an outlook of the planned final characterization steps of the camera (e.g. efficiency, linearity, sub-pixel resolution, pile-up behaviour) is given.
