The Holifield Radioactive Ion Beam Facility (HRIBF), now under construction at the Oak Ridge National Laboratory, is based on the use of the well-known on-line isotope separator (ISOL) technique in which radioactive nuclei are produced by fusion type reactions in selectively chosen target materials by high-energy proton, deuteron, or He ion beams from the Oak Ridge Isochronous Cyclotron (ORIC).Cited by: In-Target Yields for Radioactive Ion Beam (RIB) Production with EURISOL spectrum given by a liquid metal -type target-ion source assembly.

New radioactive ion beam (RIB) facilities, like FRIB in the US or FAIR in Europe, will push further away from stability and enable the next generation of nuclear physics experiments.

Thus, the need for improved RIB targets is more crucial than ever: developments in exotic beams should coincide with developments in targets for use with those beams, in order for nuclear physics to remain on the Cited by: 4.

In November ofthe ISAC radioactive beam facility at TRIUMF started delivering on-line isotope separated radioactive beams to experiments. A surface ionization source developed for ISAC has been used to commission the mass separator and beam transport systems and is providing radioactive beams to the first generation of ISAC experiments.

High Level Radioactive Liquid Waste Tanks leaving large volumes of a highly radioactive and corrosive liquid behind.

These large tanks, designed to hold the post-reprocessing liquid wastes from the military reactors at Hanford, are intended to replace older tanks which have already leaked a million gallons into the soil.

By the very nature of secondary beams, their intensity is limited, particularly for beams of the highest interest --farthest away from stability.

Radioactive sources have a variety of uses in space, ranging from power generation to instrumentation. The following are examples of typical space applications: Reactor Power Systems use the heat energy from controlled fission to drive some form of electric power generator.

The U.S. flight. radioactive, and that radioactivity cannot be shut off. So even after the fission process has been totally stopped (no more splitting of atoms), a lot of heat is still being produced by the disintegrating atoms of the radioactive waste materials in the core of the reactor.

This "unstoppable" heat, due to radioactivity alone, is called "decay heat". Beams of short-lived radioactive nuclei are needed for frontier experimental research in nuclear structure, reactions, and astrophysics.
