Hot electrons in femtosecond laser-plasma interaction
Bibliographic record
Abstract
The behaviors of hot electrons in femtosecond laser-plasma interaction have been studied systematically under laser irradiance of 5 X 10<SUP>15</SUP> Wcm<SUP>-2</SUP>micrometers <SUP>2</SUP>. A very directional jet emission of hot electrons with energies above 170 keV has been observed in the normal direction to the target surface. The angular distribution of the jet emission of hot electrons has been found to be dependent on the energy of hot electrons. By measuring the Faraday rotation angle of the backscattered emission, a magnetic field in the axial direction has been detected for the first time. The maximum value of the magnetic field was estimated to be as high as 1.76 +/- 0.7 Mgauss at such a modest irradiance. It is believed that this axial magnetic field is generated by the dynamo effect in the laser-plasma interaction.

How this classification was reachedexpand
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.
