Worldwide Cyclotron Directory
A worldwide directory of cyclotrons: 1,564 machines in 92 countries, hand-verified against public sources, which are retained and available to researchers on request. It covers research, teaching, medical isotope, proton therapy, amateur, and industrial machines at every lifecycle stage the census tracks, from under construction through operating to decommissioned and preserved in museums. Amateur builds are shown at city level only; the builds directory carries their full stories. 30 of the machines run public tours — the ★ markers and the “Public tours only” filter show them, and each record’s popup links its facility’s own tour page.

Cyclotrons you can visit
30 machines in the directory offer public tours and 71 more can be visited by arrangement. The ★ markers and the “Public tours only” filter show them on the map; each machine’s popup links the facility’s own tour page, which is the authority on current hours, booking, and age limits.
