The TRIUMF Isotope Separator and Accelerator (ISAC) facility uses the isotope separation on-line (ISOL) technique to produce rare-isotope beams (RIB). The ISOL system consists of a primary production beam, a target/ion source, a mass separator, and beam transport system. The rare isotopes produced during the interaction of the proton beam with the target nucleus are stopped in the bulk of the target material. They diffuse inside the target material matrix to the surface of the grain and then effuse to the ion source where they are ionized to form an ion beam that can be separated by mass and then guided to the experimental facilities. Previously published in the journal Hyperfine Interactions.

The Isotope Separator and Accelerator (ISAC) facility located at the TRIUMF laboratory in Vancouver, Canada, is one of the world's most advanced ISOL-type radioactive ion beam facilities. An extensive {gamma}-ray spectroscopy program at ISAC is centered around two major research facilities: (1) the 8{pi} {gamma}-ray spectrometer for {beta}-delayed {gamma}-ray spectroscopy experiments with the low-energy beams from ISAC-I, and (2) the next-generation TRIUMF-ISAC Gamma-Ray Escape Suppressed Spectrometer (TIGRESS) for in-beam experiments with the accelerated radioactive ion beams. An overview of these facilities and recent results from the diverse program of nuclear structure and fundamental interaction studies they support is presented.

Development of a facility combining an isotope-separator-on-line (ISOL) with a post-accelerator, to produce energetic ion beams far from the valley of nuclear stability, was originally proposed for installation on one of the beam lines of the TRIUMF cyclotron about ten years ago. A test facility (TISOL) consisting of a target, ion source, and mass separator, but without a post accelerator, was subsequently installed and has been in use to support an experimental program and to aid in development of target/ion source systems. The facility is currently being augmented with the addition of a laser neutral atom trap for a proposed series of[beta] decay and atomic parity non-conservation experiments, using selected radioactive alkali isotopes, to test some symmetry properties of the Standard Model. In addition, work has begun on a new upgraded facility consisting of remotely handleable target/ion source assemblies, a new mass separator with resolution m/[Delta]m= 10,000, and post-acceleration to 1.5 MeV/u, for ions with A[le] 30.

The TRIUMF/ISAC facility, now a world leader in rare isotope production and acceleration, is constructing ISAC-II [1, 2], that will allow the acceleration of ion beams with 3 (less-than or equal to) A/q (less-than or equal to) 7 to an energy of at least 6.5 MeV/u for masses up to 150. The upgrade will include the addition of a superconducting heavy-ion linac delivering an effective voltage of 43 MV. The first order design of the new transfer lines and post-accelerator have been optimized to provide simultaneous acceleration of several charge states (multicharge). The quarter wave resonators providing the acceleration have inherent rf electric and magnetic asymmetric components that complicate multi-charge acceleration and can lead to transverse emittance growth. In particular we report the realistic field simulations of the medium beta section of the SC-DTL for multi-charge acceleration.

The Holifield Radioactive Ion Beam Facility (HRIBF) is a first generation national user facility for nuclear physics and nuclear astrophysics research with radioactive ion beams (RIBS). The reconfiguration, construction, and equipment-commissioning phases have been completed and the beam development program is in progress. In this article, descriptions of the facility and newly implemented experimental equipment for use in the nuclear and astrophysics programs will be given and an outline of the initial experimental program will be presented. Special target/ion source related problems, endemic to the production of specific short-lived RIBs will be discussed. In addition, plans, which involve either a 200-MeV or a 1-GeV proton-linac driver for a second-generation ISOL facility, will be presented.

Rare Isotope Beams (RIBs) are ion beams of exotic radioactive nuclei. The study of these nuclei is key to understanding the limits of nuclear existence, nucleo-synthesis in such violent stellar sites as supernovae and merging neutron stars, and the fundamental symmetries of nature. These nuclei also provide a unique probe to study condensed matter and many of them are potentially new radioisotopes for more effective medical diagnostics and therapy. Rare Isotope Beams: Concepts and Techniques gives an up-to-date overview of all these aspects of RIB science in a single volume containing the scientific motivation, production techniques, experimental techniques for studying exotic nuclei, methods used in condensed matter research, and medical applications. The emphasis throughout is on concepts to facilitate understanding of the essence of each topic in this diverse and cross-disciplinary field involving nuclear physics, astrophysics, and particle accelerators. A brief description of major RIB facilities is also presented. Exotic nuclei are difficult to produce in enough numbers and their production involves different nuclear reaction routes and a wide range of advanced technologies, which are presented in a comprehensive manner. Experimental techniques used to study exotic nuclei are provided with examples highlighting the intricate nature of such experiments. Another unique feature is the open-ended nature of the discussions, bringing out the future challenges and possibilities in this evolving field. The book offers an excellent overview of concepts and techniques involved in RIB science for new researchers entering the field as well as professionals.
