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
