Abstract
We present a novel approach in fast imaging of high-power impulse magnetron sputtering (HiPIMS) discharges in which bandpass optical interference filters are used to isolate the optical emission signal originating from different species populating the plasma. In this paper, we describe the methodology of the proposed diagnostics and discuss its application. In particular, we demonstrate the use of this technique for the time-resolved analysis of HiPIMS discharges operated with a chromium cathode in argon at 4 Pa. Two optical filters were designed and fabricated: (i) one for neutral chromium emission lines (400-540 nm); and (ii) the other one for neutral working gas emission lines and bands (above 750 nm). The introduction of such filters is used to distinguish different phases of the discharge and to reveal numerous plasma effects including background gas excitations during the discharge ignition, gas shock waves, and expansion of metal-rich plasmas.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
