Abstract
We report on the preparation of hydrogen-free nanocrystalline diamond films by pulsed electron beam ablation (channel-spark) from a single target on silicon and stainless steel substrates and under different process conditions. The films have been grown from highly ordered pyrolytic graphite at room temperature in an argon atmosphere under a pressure of 0.6 Pa. This study aims at elucidating the influence of the accelerating voltage (13, 14.5, and 16 kV) and electron beam pulse repetition rate (5 and 8 Hz) on film morphology, grain size, carbon-carbon sp3 content, and crystalline fraction. The films have been characterized using visible-reflectance spectroscopy, visible-Raman spectroscopy, scanning electron microscopy (SEM), and atomic force microscopy (AFM). The correlations between measurement data and film properties are examined and discussed.

Full frame distilled prediction
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
