Abstract: Recently X-ray spectrometers with spherically curved large crystals, which are designed for the diagnostics of extended X-ray sources, have been shown to reach a throughput of an order of magnitude more than the usual cylindrically curved Johann crystal spectrometers, for large Bragg angles. Here, the possibility of applying 2D curving also to ground and curved Johansson crystals is discussed, to further enhance the throughput.
