Abstract
The ISOL facility TRIUMF-ISAC utilizes a number of different ion sources to produce radioactive ion beams. Most isotopes are ionized using surface or resonant laser ionization, but these techniques are prohibitively inefficient for species with high ionization energies, such as noble gases and molecules. For these cases, the Forced Electron Beam Induced Arc Discharge (FEBIAD) ion source can be used. The FEBIAD uses a hot cathode to produce electrons, which are accelerated through a potential (< 200 V) into the anode volume. Isotopes entering the resulting plasma undergo impact ionization and are extracted. Efforts are under way to better understand the physics and operation of the FEBIAD, using both theory and experiment. Recent measurements and simulations on the ISAC FEBIAD will be reported here.

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
