Rare Isotope Beam Production and Separation Methods

Accelerator Design for a 1⁄2 Mw Electron Linac for Rare Isotope Beam Production

TRIUMF, in collaboration with university partners, proposes to construct a megawatt-class electron linear accelerator (e-linac) as a driver for radioactive beam production for nuclear structure and astrophysics [1] and material science. The design strategy, including upgrade path, for this cost-effective facility is elaborated. The 50 MeV, 10 mA, c.w. linac is based on TTF superconducting (SC) ...

Isotope Effects, Isotope Separation and Isotope Fractionation

Electrochemical isotope effect and lithium isotope separation.

A large electrochemical isotopic effect is observed upon the electrodeposition of lithium from solutions of propylene carbonate producing isotopically light metal deposits. The magnitude of fractionation is controlled by the applied overpotential and is largest close to equilibrium. Calculated partition function ratios for tetrahedrally coordinated lithium complexes and metallic lithium predict...

Beam Optics Study of a Fragment Separator for the Planned Rare Isotope Beam Facility in Korea

A heavy-ion accelerator facility based on a linear accelerator is planned in Korea. The facility is designed to provide high-current radioisotope beams, and they will be utilized in the fields of nuclear, material and biomedical sciences. The primary beam energy is in the range of a few hundreds of MeV/u. A major mechanism to produce isotope beams is in-flight fragment separation. The separator...

Rare isotope production near the neutron drip line

The underlying mechanism involved in the production of very neutron-rich nuclides using projectile fragmentation is studied with an abrasion-ablation ~AA! model. The AA model suggests that very neutron-rich nuclides are produced by removing nearly all the required protons in the nonequilibrium abrasion stage, with minimal evaporation of neutrons in the ablation stage—‘‘cold fragmentation.’’ Fur...
