Beamline spectrograph


Soft X-ray / XUV / VUV Spectrograph


Our soft X-ray / XUV / VUV spectrograph EVEREST has a modular design to give maximum flexibility, incorporating three gratings that can be individually selected or combined to cover the spectral ranges 1-17 nm (73 – 1240 eV), 5-80  nm (15 – 248 eV), and 30-200 nm (6 – 41 eV).

Featuring aberration-corrected flat-field imaging and with the possibility to operate it without an entrance slit, the device has been carefully developed to maximize the reflectivity, collection efficiency and detection of the entire spectrum at each laser shot.

The spectrograph includes an integrated slit holder, gate valve, filter insertion unit, and motorized grating positioning along 3 axes, as well as a flexible choice of detectors between an X-ray CCD camera or an MCP camera system.
