BEARS: radioactive ion beams at Berkeley

A light-isotope radioactive ion-beam capability has been added to the 88-in. Cyclotron at Lawrence Berkeley National Laboratory by coupling to the production cyclotron of the Berkeley Isotope Facility. The connection required the development and construction of a 350 m gas transport system between the two accelerators as well as automated cryogenic separation of the produced activity. The "rst beam developed, 11C, has been successfully accelerated with an on-target intensity of 1]108 ions/s at energies of around 10 MeV/u. ( 2000 Elsevier Science B.V. All rights reserved.
