Experimental improvements of the FANTASIO experimental setup
Bibliographic record
Abstract
The FANTASIO [1] is an experimental setup for measuring highly resolved rovibrational spectra of molecules and van der Waals complexes formed in a supersonic expansion. The continuous wave cavity ringdown spectrometer is used for probing the species in the near IR region (~1.4 microns, 0.9eV). A pulsed slit nozzle is used to increase the interaction path between the laser and the molecular beam. In the present work, I am going to show the last improvements of the slit nozzle including its new design and the profile of the new slit jaws. The valve can produce expansion from the slit nozzle with a length of up to (80 mm). This provides really intense molecular beam with homogeneous densities and temperature distributions along the slit. This new design will be compared with our previous valve based on a 30 mm long slit and Parker series 9 valve with a multichannel bloc [2]. Consequently, of the increase of signal-to-noise ratio new rovibrational bands of H20-Ar in the 2OH stretching overtone range were observed and will be presented. 1.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
