Current status and perspectives of the ACCESS project
Bibliographic record
Abstract
The ACCESS project (Array of Cryogenic Calorimeters to Evaluate Spectral Shapes) aims to establish a novel technique to perform precision measurements of forbidden beta-decays, whose spectral shape is a crucial benchmark for Nuclear Physics calculations and plays a pivotal role in Astroparticle Physics experiments. ACCESS will operate a pilot array of four tellurium dioxide crystals as cryogenic calorimeters at 10 mK. Three of them will be doped with different beta emitters (99Tc, 151Sm, 210Pb/210Bi), while the last natural one will be used for effective background subtraction. In the intermediate steps of the project also natural crystals such as cadmium tungstate (CdWO4) and indium dioxide (In2O3) will be used to investigate the beta decay of 113Cd and 115In respectively. In this work, we will describe the ACCESS project, summarizing the current status and future perspectives. Moreover, we will discuss the preliminary results obtained with indium-based crystals operated as cryogenic calorimeters.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
