Description

A new X-ray spectrometer for soft X-rays has recently come into operation at the French national synchrotron facility. The design targets of AERHA (Adjustable Energy Resolution – High Acceptance) aimed at optimized trade-off between energy resolution and instrument transmission. The instrument covers energies between 50 and 1000 eV with a resolving power in excess of 6000 while maintaining an effective angular acceptance higher than 100 micro-steradians. The first part of my talk will be focused on considerations of optical design and implementation, also showing the first recorded spectra. Our scientific interests and the opportunities offered by the new instrument will be discussed and placed in perspective relative to experiments performed at other light sources.
