Abstract

fetched live from OpenAlex

An integrating fast readout detector is being developed for the X-ray Pump Probe (XPP) instrument at the Linac Coherent Light Source (LCLS). The detector is based on X-ray Active Matrix Pixel Sensors (XAMPS) with their dedicated readout ASICs. It covers a dynamic range of more than 10,000 photons of 8 keV energy with a resolution better than half photon FWHM. The frame of 1024 × 1024 pixels will be read out within the repetition rate of the X-ray laser pulses which will be as fast as 120 Hz. The structure of the sensor allows full fill factor and -100% efficiency at the energy of interest.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
