CsI Electromagnetic Calorimeter Development for a Low or Medium Energy e+e- Collider
Bibliographic record
Abstract
Design considerations for an electromagnetic CsI calorimeter suitable for use at low and medium energy, high-luminosity e+e-storage rings are presented, together with results of a test of an array of CsI(Tl) crystals in an e-/ z-beam (120 to 400 MeV) at TRIUMF.The crystal array used in the test was designed to explore longitudinal and transverse crystal segmentation, and a redundant wavelength-shifter and photodiode readout system.Energy resolution of (1.69 f 0.08)%/@ and (1.83 f O.OS)%/& was obtained for two different crystal tower configurations.Position resolution of 6.5 (9.0) mm was obtained at 300 (120) MeV for four 4 x 4 cm2, 4 rl.CsI crystals.

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.
