Study of nuclear reactions with intense, high-purity, low-energy radioactive ion beams using a versatile multi-configuration dual superconducting-solenoid system
Abstract A new device (TwinSol) installed at the Nuclear Structure Laboratory at the University of Notre Dame implements a pair of large-bore 6 T superconducting solenoids for producing relatively pure, high-intensity beams of exotic light nuclei at low-energies (10–80 MeV). Typical beams include 8 Li and 6 He (T 1/2
Fusion Induced by Radioactive Ion Beams
The use of radioactive beams opens a new frontier for fusion studies. The coupling to the continuum can be explored with very loosely bound nuclei. Experiments were performed with beams of nuclei at or near the proton and neutron drip-lines to measure fusion and associated reactions in the vicinity of the Coulomb barrier. In addition, the fusion yield is predicted to be enhanced in reactions involving very neutron-rich unstable nuclei. Experimental measurements were carried out to investigate if it is feasible to use such beams to produce new heavy elements. The current status of these experimental activities is given in this review.
Design and performance of a new magnetic spectrograph for accurate energy measurements
Abstract A large broad-range magnetic spectrograph of a new design is described. The primary requirement of accuracy is achieved with a single dipole magnet, fixed focal surface and high dispersion. A large energy range of Emin/Emax=3.7, a solid angle up to 2.8 msr in the normal mode, and an energy resolution greater than 3000 over much of the range make it an excellent instrument for reaction energy measurements. The design, construction and testing are described.
