Abstract

The BEARS project at Lawrence Berkeley National Laboratory is developing the capability for some proton-rich radioactive beams using a coupled-cyclotron method. Initial studies have focused on ¹¹C and ¹⁴O and the first physics experiment is complete using ¹¹C in batch mode. Ionization efficiencies have been measured as high as 11% for ¹¹C⁺⁴. The total efficiency for ionization and acceleration is approximately 1% and total beam intensities of 1×10⁸ have been observed. Upon completion of the transfer line, beam intensities of 2×10⁸ are expected for ¹¹C and 5×10⁶ for ¹⁴O
