Figure 6
(a) VUVCD baselines measured under vacuum without a CaF2 cell at the end-station. Red dashed line: CD baseline before orientation of the PMT to the optimum angle. Black solid line: PMT oriented to the optimum angle. The baseline amplitude is as small as ±2 mdeg for the spectral range 130–320 nm. (b) Baseline spectra acquired without (black solid line) and with (green dashed line) the CaF2 sample cell. All spectra were recorded with slit width 300 µm, single scan, time constant 1 s and wavelength increments 0.6 nm.
