A customized parallel plate radiation sensor for evaluation of ionization collection efficiency
Bibliographic record
Abstract
Radiation sensors play an important role in radiation therapy. In this paper, a customized parallel plate radiation sensor with thick and large-area electrodes was designed and made as a precursor to investigating novel materials as a substitute for conventional metallic conducting plates. Measurements by varying the bias voltages, electrode separations, doses and angles of the incident beam were carried out to characterize the sensor. Saturation characteristic of the sensor with different electrode separations and doses was investigated using the Varian Clinac 21 EX medical linear accelerator. Our prototype sensor displayed excellent linear response to dose up to 600 monitor units (MU) and showed an accurate response to the oblique incident beam with a small field size of 1 /spl times/ 1 cm/sup 2/. The sensor was tested to be suitable in the study on the ionization collection efficiencies for different materials.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
