While these experiments were not made online, the rig was designed so that this might be possible. Researchers also used a Czerny-Turner spectrometer (SP-750 Acton Research Corporation) and ICCD (Princeton Instruments) for some experiments. This, however, limited the spectral range to 4nm. Experimenters did try using 1064nm Nd:YAG fundamental for some measurements, but found the reproducibility inferior the 266nm. Significant improvement in calibration curves from normalisation to the C I peak at 247.856nm
