Abstract
We review here our recent work on a high dynamic range, subpicosecond x-ray streak camera. Our subpicosecond streak camera (PX1) has been coupled to a 10 Hz Ti: sapphire laser system and tested with 500 fs UV light pulses (266 nm) in jitter-free accumulation mode. A novel design for the photoconductive switches that are coupled to the camera’s deflection plates has been successfully used to eliminate the jitter induced by the laser intensity fluctuations and by the temporal shape of the laser beam. Results demonstrate that this detection system gives simultaneously a high dynamic range and a subpicosecond resolution at a repetition rate of 10 Hz.

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
