We introduce a compact and large angle acceptance soft X-ray spectrometer for an energy range of 1-3 keV suitable for experiments under the above conditions. The spectrometer uses a von Hamos optical design covering a simultaneous energy window of >300 eV at a resolving power of 1200-2800 and a total length of the spectrometer of <600 mm. We will present design details and first performance test results. PB - JACoW Publishing CP - Geneva, Switzerland ER -
