A study of the emission spectra from discharges on an ice surface
Bibliographic record
Abstract
Spectra of the emitted light from an arc formed on an ice surface over a wide range (300-850 nm) were studied using a triggered spectrometer. Detailed analysis of the spectra allowed identifying different atomic lines and molecular bands from the background gases, as well as excited species from polluted ice. Time-resolved spectra were recorded at different stages of arc propagation over an ice surface to gather data on the occurring ionization processes. From comparisons of overall spectra of white and flashover arcs, it was observed that a white arc emits light mostly in the ultraviolet region, whereas a flashover arc emits light mostly in the visible region. It was pointed out that the intensity of some lines, such as copper, increases constantly between the white arc and flashover occurrences. However, the intensity of some lines, such as Hαand Hβand N2+first negative, increases suddenly during flashover. The possible chemical reactions responsible for emitting observed lines and bands were discussed.

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.
