Influence of freon on charge density build-up in a solid insulator
Bibliographic record
Abstract
The charge generation at the surface of and within an acrylic glass spacer was measured using a capacitive probe in freon as a function of gas pressure and the level, duration and polarity of a dc applied voltage. Typically the rate of charge build up increased with increasing gas pressure from 0.174 /spl mu/C/m/sup 2//s at 0.1 MPa to 0.97 /spl mu/C/m/sup 2//s at 0.4 MPa a fixed applied voltage of 80 kV. At a fixed gas pressure of 0.1 MPa the charge build up increased from 2.6/spl times/10/sup -3/ /spl mu/C/m/sup 2//s at 2 kV to 174/spl times/10/sup -3/ /spl mu/C/m/sup 2//s at 80 kV. The saturated charge density increased linearly with increasing voltage from 1.3 /spl mu/C/m/sup 2/ at 2 kV to 61.2 /spl mu/C/m/sup 2/ at 80 kV, for 0.1 MPa. The charging current was also monitored and found to decrease rapidly with increasing time until saturation is reached. The saturated current increased, at a fixed pressure, with increasing voltage. It also increased with increasing pressure at a fixed applied voltage. The observed charge build up is governed by the total surface and volume resistances of the insulator.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
