A 40 keV cyclotron for radioisotope dating

Detection of radiocarbon in the cyclotrino

“…Design of this cyclotron is essentially the same as that described previously by our group (4)(5)(6)(7)(8)(9)(10). A beam of carbon ions is introduced into the cyclotron.…”

“…A small cyclotron (the "cyclotrino") was built at Berkeley to test these concepts [4][5][6][7]. This cyclotron incorporated a miniature Cs sputter negative ion source at the center of the cyclotron, injecting negatively-charged carbon ions at about 3 ke V. Extraction energy was about 40keV at about a 10.5 em radius.…”
