Abstract
The Spherical Proportional Counter is a large-volume gaseous detector that finds application in many fields, like α, β, γ radiation detection, neutrino detection and Dark Matter research. When a reaction happens close to the detector wall it is possible for the produced particles to hit the wall and lose energy. This is known as the wall effect and it leads to wrong calculations of the incident particle energy. It depends on the particles’ range and the detector characteristics, such as its size and the gas pressure. In this work, a study has been done in order to quantify the wall effect for the SPC, for any application. We used neutron beams, which cover the total volume of the sphere and interact with the gas nuclei, giving several reactions. The presented data derive from simulations on GEANT4 and are in agreement with the experimental data from neutron beams of the TANDEM Accelerator Laboratory, NCSR Demokritos.

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
