About

Cyclotron Info is a reference site for cyclotron enthusiasts — students, hobbyists, amateur builders, and anyone curious about particle accelerators. It exists because the knowledge needed to understand, design, and (where lawful) build a small cyclotron is scattered across decades of literature, defunct project pages, and institutional archives. This site collects it in one place.

Sources and accuracy

Design rules, formulas, and legal summaries on this site carry citations to their sources. The material is curated from published accelerator literature — from the 1940s classics through modern references — and from primary legal texts. It is provided for education: verify anything safety-critical or legally-significant against the cited primary source before relying on it.

Privacy

This is a static site. It sets no cookies, runs no analytics, and collects no personal data. The exception is the interactive map on the Locations page, which loads map tiles from OpenStreetMap; no other page makes third-party requests.
