Adding missing "facility" references. 2025-01-23 1.0 Initial version. urn:nasa:pds:context:facility:laboratory.mhc instrument_to_facility SuperLIBS Spectrometer LIBS SuperLIBS was designed and built by Princeton Instruments using 2D CCD detectors identical to those fabricated for the SuperCam LIBS on the Mars 2020 rover. It employs increased sensitivity Princeton IsoPlane-160 spectrometers and uses stacked fiber bundles to deliver light to spectrometers. PIXIS cameras were used to detect plasma light in the UV and VIS regions, while a PI-MAX4 camera with a gated intensifier was used in the VNIR region. High-resolution gratings in the spectrometers enabled a spectral resolution greater than 0.08 nm in the UV, VIS, and VNIR regions. A lower resolution grating was also be used in the VNIR grating, with a wavelength resolution of 0.43 nm. Sample ablation is performed using a Quantel Ultra100 laser operating at 1064 nm, up to 15 mJ/pulse, 10 Hz, with a 6-ns pulse width. An 80/20 beamsplitter is placed in the beam path to monitor laser energy. Any given laser attenuation values should be multiplied by 0.8 to calculate the laser energy on target. A 24×24×18" Mars vacuum chamber includes an automated XY translation stage to increase sample throughput to 100 samples per run. Spectra were collected at three to four different laser energies under Earth (~760 Torr), vacuum (~100-300 mTorr), and a Mars-like (7 Torr CO2) conditions.
