Abstract
The spiral inflector steers the beam from the bore in the main magnet into the median plane to achieve the axial injection with an external ion source. In a conventional electrostatic infector, the injection beam energy is limited by the breakdown voltage on the electrodes. At the same time, the injection intensity is also limited by the small aperture in the electrostatic inflector. Magnetic inflector is a promising alternative to overcome these disadvantages. To demonstrate the technology, we use the TR100 main magnet model, a conceptual idea of an H²⁺ cyclotron, as a testbench to study the inflection conditions and optics of the passive magnetic inflector with a cylindrically symmetric structure. A mirror-like field with optimized mirror length and ratio provides a well-focused beam arriving at the median plane. The required magnetic field is produced by shimming a center plug in the injection hole. The space charge effect is also discussed with the simulation of a high-intensity injection beam.

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
