Abstract
Elemental silver was diffused in a number of polyimide (C22H10N2O5, PMDA-ODA, Kapton-H) samples using the developed method of 6MeV electron irradiation. The virgin and the silver diffused polyimide samples, each of dimension 12×12×25μm, were irradiated with electrons of different energies, varying from 2to20keV. Each sample was irradiated with single energy electrons for a period of 300s, at a current density of ∼50nA∕cm2. The variations in the sample current and the backscattered electron current with the irradiation period were studied. The gaseous species evolved from the polyimide during electron irradiation were investigated by a quadrupole mass spectrometer. The negative charge stored and the surface potential developed in the polyimide increased with increasing electron energy, even though the irradiation period and the incident electron current were kept constant. This phenomenon is attributed to the decrease in the number of the backscattered electrons and the increase in the number of charged gaseous species that evolved from the polyimide surface with increasing energy of the incident electrons. For the same electron energy and fluence, the charge stored in the silver diffused polyimide was lower than that developed in the virgin polyimide. This property of the silver diffused polyimide is desirable for the space applications.

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
