Abstract

fetched live from OpenAlex

Using 10–60 krad doses of cobalt 60 gamma radiation, the effect of simulated space radiation on 1 mm 2 active area silicon photodiodes with a sapphire window is studied. The diodes will be used to control the laser output of a space experiment in geostationary orbit. The effect of 1 MeV electron irradiation with various fluences on 100 mm 2 silicon photodiodes/solar cells, which were used to control the attitude of a satellite in space, is also studied here. Fluences ranging from 3 x 10 14 to 1 x 10 15 cm –2 of 1 MeV energy, caused a decrease in the short-circuit current, i.e., increasing the percentage of deterioration from 12% to 20% at a room-temperature measurement. Exposure to the gamma irradiation yields almost no degradation for the electro-optical performance of the devices. The manufacturing processes of the detectors and their electro-optical I–V characteristics such as fill factor, responsivity, and dark current are presented here. Electro-optical tests were also done at intermediate levels of irradiation. High stability and high quality of the photodiodes were achieved prior to and after irradiation. PACS No.: 84.60J

Full frame distilled prediction

Teacher imitation

Not 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.
