Production of exotic beams at the LBL 88-Inch Cyclotron by the ISOL method.

摘要

The Users of the LBL 88-Inch Cyclotron are preparing a proposal to produce exotic, i.e., radioactive beams. The facility will consist of a high-current 30 MeV cyclotron to generate the radioactive nuclei, an ECR source that can be coupled to different production targets, and the 88-Inch Cyclotron to accelerate the radioactive ions. Thus, the basic concept is that of the double cyclotron system pioneered at Louvain-la-Neuve, although the initial emphasis will be on producing a variety of light proton-rich beams at energies up to 10 MeV/A. At this workshop we wish to outline what is being planned, to invite comments and suggestions, and, especially, to encourage participation. We believe that this facility will be an important step toward establishing the scientific and technical basis for a National High Intensity Facility. This can be achieved through active participation by members of the radioactive beam (RB) community in (1) experiments with high quality radioactive beams of moderate intensity and, (2) R&D on high beam-power targets and highly efficient ion sources. 5 refs., 4 figs.
