Locations
1,257 machines in 92 countries, hand-verified against primary sources — see the registries the verification draws on. Amateur builds are shown at city level only; the builds directory carries their full stories. 31 of the machines run public tours — cyclotrons you can visit maps them, with the verified virtual tours beside them.

Cyclotrons you can visit
In person: 31 machines in the directory offer public tours and 67 more can be visited by arrangement — show the public-tour machines on the map (the ★ markers), or use the "Public tours only" filter above. Each record's tours column and notes say what is on offer.
Online: these facilities publish tours a browser can take from anywhere. All links verified August 2026; the last two are accelerator-adjacent rather than cyclotron facilities.
- TRIUMF — Discover Our Lab — interactive tour of the Vancouver site, including the Main Accelerator Building that houses the 520 MeV machine, which TRIUMF describes as the world's largest cyclotron by diameter; a companion TRIUMF 360 playlist adds 360° video.
- CERN — virtual tours and talks — live hour-long guided virtual visits with CERN guides (scheduled sessions; registration required, none may be listed between rounds).
- Cincinnati Children's Proton Therapy Center — cyclotron tour — 360° walkthrough of a working proton-therapy cyclotron and beamline.
- IRAB, Barcelona — 360° tour — a radiopharmacy production facility built around an IBA Cyclone 18/9 (18 MeV protons / 9 MeV deuterons), photographed port by port.
- Feinstein Institutes — cyclotron & radiochemistry tour — narrated photo tour of a hospital PET cyclotron vault, hot cells, and radiochemistry lab.
- ANSTO National Research Cyclotron — video tour — walk-through of Australia's 30 MeV research and isotope-production cyclotron.
- SLAC — self-guided virtual tour — interactive tour of the linear-accelerator laboratory (adjacent: a linac, not a cyclotron).
- National MagLab — 360° virtual tour — the Tallahassee magnet laboratory, including spaces normally off limits (adjacent: magnets, not accelerators).
