pub const ES_SPUTTER_AR_V1: TuningSet;Expand description
es-sputter-ar-v1: one E_s multiplier per element for Ar sputtering of
Si, Cu, Ag and Au, fitted by validation/experiments/run.py --fit-tuning
to measured yields only (the sets in validation/data/sputtering/, each
cited to its original publication in docs/data-provenance.md), with a
held-out evaluation in validation/experiments/tuning_results.json.
Phenomenological calibration, not a published value: the factors absorb
whatever the untuned matched problem misses (not shown to be E_s itself)
and were fitted under those matched settings (ZBL, Lindhard-Scharff,
constant free path, E_d = untuned E_s, E_b = 0, cutoffs 2 / 1 eV,
no weak collisions); their transfer to other settings is untested.
