Data

The datasets behind this site are available as stable JSON exports for research, teaching, and reuse. Each file carries its license and provenance in a header block.

Datasets

• Design Guide rules

  1878 rules · JSON

  Every design rule with its domains, formula, citation, verbatim source quote, tabletop applicability note, and 1–5 applicability level (breadth, not importance — see methodology). Sources are given as public citations; rules are source extracts, not validated requirements.

• Annotated bibliography

  283 documents · JSON

  The Library index: title, authors, year, era, document type, topics, editorial annotation, relevance scores, and verified outbound links where documents are legitimately available online.

• World cyclotron census (quarterly snapshot)

  1564 machines · snapshot 2026-10-04 · JSON · CSV · CC BY-NC 4.0

  The directory snapshot: identity, location with stated precision, category, current status, technical class (architecture, particles, energy), verification date, and tour availability per machine. Refreshed quarterly; the snapshot date is in the header. Records are verified against public sources, retained and available to researchers on request.
