A schematic showing the layout of the ruby laser, guiding optics, and beam dump together with the collection optics and vacuum vessel.
The measured transmission bands of the six-channel polychromator shown together with the spectrum of the calibration LED and a calculated scattered spectrum at 100 eV.
Uncalibrated detection signals (top left) from a single polychromator. The dashed lines mark the area of integration. The remaining plots show the calibrated data values and their errors together with the fitted spectrum. The data points near zero represent the stray light levels.
