Transport of Dust Particles in Very Low-Pressure Magnetized Plasma Studied by Rapid Imaging
Bibliographic record
Abstract
Incandescent dust particles are observed to the naked eye in pure acetylene plasmas excited at electron cyclotron resonance (ECR). Their transport in a plane parallel to the magnets is studied using fast imaging combined with a tracking algorithm. The dynamics of dust particles exhibit specific trends depending on the direction considered within the magnetic field (B⃗), the position in the plasma reactor, and the time after plasma ignition. This transport is discussed considering the electric and the ion drag forces. Although the transport of dust particles is governed by the space-charge electric field in the direction parallel to B⃗, it involves cross-field mechanisms in the direction perpendicular to B⃗ related, specifically, to the ambipolar E⃗ x B⃗ drift as supported by a simple model. However, to fully describe these transport phenomena, one would also consider spatial and time-evolutions of plasma parameters in the dusty plasma.

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.
