Changelog
A dated record of what changed on this site: content additions, data updates, and substantive corrections, newest first. How the content itself is produced is documented in the editorial methodology.
- — Editorial transparency: methodology page documenting how each section was produced and defining the status vocabulary; this changelog; Design Guide caveat now states the source-extract status explicitly; Library exportable as BibTeX.
- — Homepage reframed around what the site is for, with a beginner start-here path; standard educational-reference notice added to the Calculators and Design Guide.
- — Corpus update: Design Guide grown from 560 to 634 rules (new extraction domain); Library grown from 186 to 201 entries with 8 newly verified outbound links.
- — Citations upgraded: every design rule now shows its full source title linked into the Library; 75 verified outbound links to freely available source documents.
- — Review-driven fixes: skip-to-content link, corrected heading hierarchy, corrections policy on About, search added to navigation; News filtering rebuilt with a measured include/exclude list and fallback so the page never goes empty.
- — Preserved from the old site: patents research page, verified virtual facility tours on Locations, and an expanded communities directory.
- — Site search added: self-hosted Pagefind index across all content pages; no third-party services.
- — Glossary published: 92 cross-linked cyclotron terms.
- — Locations census updated to 530 machines after a verification pass against the IAEA facility list.
- — Graphics and interactivity wave: animated cyclotron and physics figures on Learn, interactive anatomy diagram on the Design Guide, hazard-zone figure and shielding widget on Safety, live geometry diagrams on all seven calculators, historical energy chart, amateur-builds timeline, and the world cyclotron map.
- — Added under Library: a verified external-resources directory and a free-modeling-software guide organized by design question.
- — Site rebuild launched with the full section set: Design Guide (560 rules at launch), seven Calculators with derivations, Legal survey (federal layer plus 51 US jurisdictions), Library (186 entries at launch), Builds (17-machine amateur census), Learn (theory, history, applications, safety, starter path), News, Locations, and About with a public contact address.
- — Rebuild started on a new static architecture, replacing the 2021 WordPress site.
