Available in PDF, EPUB and Kindle. Book excerpt: There is considerable interest worldwide in the research which could be done at a next generation, advanced radioactive beam facility. To generate high quality, intense beams of accelerated radionuclides via the {open_quotes}isotope separator on-line{close_quotes} (ISOL) method requires two major accelerator components: a high power (100 kW) driver device to produce radionuclides in a production target/ion source complex, and a secondary beam accelerator to produce beams of radioactive ions up to energies on the order of 10 MeV per nucleon over a broad mass range. In reviewing the technological challenges of such a facility, several types of modem linear accelerators appear well suited. This paper reviews the properties of the linacs currently under construction and those proposed for future facilities for use either as the driver device or the radioactive beam post-accelerator. Other choices of accelerators, such as cyclotrons, for either the driver or secondary beam devices of a radioactive beam complex will also be compared. Issues to be addressed for the production accelerator include the choice of ion beam types to be used for cost-effective production of radionuclides. For the post-accelerator the choice of ion source technology is critical and dictates the charge-to-mass requirements at the injection stage.
Download or read book Ion Sources for Induction Linac Driven Heavy Ion Fusion written by and published by . This book was released on 1993 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of ion sources in induction linacs for heavy ion fusion is fundamentally different from their use in the rf linac-storage rings approach. Induction linacs require very high current, short pulse extraction usually with large apertures which are dictated by the injector design. One is faced with the problem of extracting beams in a pulsed fashion while maintaining high beam quality during the pulse (low-emittance). Four types of sources have been studied for this application. The vacuum arc and the rf cusp field source are the plasma types and the porous plug and hot alumino-silicate surface source are the thermal types. The hot alumino-silicate potassium source has proved to be the best candidate for the next generation of scaled experiments. The porous plug for potassium is somewhat more difficult to use. The vacuum arc suffers from noise and lifetime problems and the rf cusp field source is difficult to use with very short pulses. Operational experience with all of these types of sources is presented.

Download or read book Ion Sources and Injectors for HIF Induction Linacs written by and published by . This book was released on 2000 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ion source and injector development is one of the major parts of the HIF program in the USA. Our challenge is to design a cost effective driver-scale injector and to build a multiple beam module within the next couple of years. In this paper, several current-voltage scaling laws are summarized for guiding the injector design. Following the traditional way of building injectors for HIF induction linac, we have produced a preliminary design for a multiple beam driver-scale injector. We also developed an alternate option for a high current density injector that is much smaller in size. One of the changes following this new option is the possibility of using other kinds of ion sources than the surface ionization sources. So far, we are still looking for an ideal ion source candidate that can readily meet all the essential requirements.

Download or read book Heavy ion Linac for Medical and Scientific Research written by and published by . This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Electron Beam Ion Source (EBIS), because of its high charge state ions and pulsed operation, is ideally suited as an injector for a heavy-ion linac based on the technology being developed at the Los Alamos Scientific Laboratory (LASL) in the program to design a Pion Generator for Medical Irradiation (PIGMI). This combination would produce a small efficient heavy ion linac useful in relativistic heavy-ion research or therapy. The radio-frequency quadrupole linac (RFQ), a new, low velocity accelerating structure in use at LASL, makes this possible because it can accelerate the fully stripped ions generated in an EBIS from a very low injection energy to an energy convenient for use in a conventional linac, with almost complete capture of the ions. If the conventional linac is a high-gradient low duty-cycle structure such as the proposed PIGMI accelerator, this accelerator system thus realizes maximum use of the ions produced in the EBIS with minimum size and power consumption in the linac. This accelerator could be extended to energies useful for relativistic heavy-ion medical therapy or physics research, or could be used as an injector for a synchrotron.
