A proposal for an additional beamline to the Triumf ISAC facility
Bibliographic record
Abstract
The present ISAC facility at TRIUMF is fed by one beamline, beamline 2A, that can direct beam to one of two target locations. One of these targets has been in use since ISAC was commissioned; the second is currently being commissioned. The number of proposals for experiments at ISAC are such that we feel the need to deliver more simultaneous radioactive ion beams. A proposal has been made for an another beamline to ISAC so as to make additional beams available. Through partial extraction by H/sup -/ stripping, this proposed line would extract a 450-500 MeV beam from extraction port 4 of the TRIUMF cyclotron. A fast switching system would be used to feed an additional two target stations, each equipped with its own mass-separator system. These new target stations will allow target and ion-source development, and also at least three simultaneous experiments at ISAC. In addition to these two target stations, provision for a 200 /spl mu/A beam dump has been made.

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.
