Book excerpt: The positive ion injector project will replace a High Voltage Engineering Corp. model FN 9 MV tandem electrostatic accelerator as the injector into the ATLAS superconducting heavy ion linear accelerator. It consists of an electron cyclotron resonance (ECR) ion source on a 350-kV platform injecting into a linac of individually phased superconducting resonators which have been optimized for ions with velocities as low as .beta. = 0.009. The resulting combination will extend the useful mass range of ATLAS to projectiles as heavy as uranium, while increasing the beam currents available by a factor of 100. (2 refs., 2 figs., 1 tab.).

Book excerpt: The goal of the Argonne Positive Ion Injector project is to replace the ATLAS tandem injector with a facility which will increase the beam currents presently available by a factor of 100 and to make available at ATLAS essentially all beams including uranium. The beam quality expected from the facility will be at least as good as that of the tandem based ATLAS. The project combines two relatively new technologies - the electron cyclotron resonance ion source, which provides high charge state ions at microampere currents, and RF superconductivity which has been shown to be capable of generating accelerating fields as high as 10 MV/m, resulting in an essentially new method of acceleration for low-energy heavy ions. 5 refs., 7 figs., 1 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: This paper summarizes the status and first operational experience with the positive-ion injector for ATLAS. The new injector consists of an ECR ion source on a 350-kV platform, followed by a superconducting injector linac of a new kind. In Phase I of this project, the ECR source, voltage platform, bunching system, beam-transport system, and a 3-MV injector linac were completed and tested in early 1989 by a successful acceleration of an 4°Ar/sup 12 +/ beam. Most of the new system operated as planned, and the longitudinal emittance of the 36-MeV beam out of the injector was measured to be only 5 .pi. keV-ns, much smaller than the emittance for the present tandem injector. When completed in 1990, the final injector linac will be enlarged to 12 MV, enough to allow the original ATLAS linac to accelerate uranium ions up to 8 MeV/u. 8 refs., 2 figs.

Book excerpt: This paper reviews the design, construction status, and beam tests to date of the positive ion injector (PII) which is replacing the tandem injector for the ATLAS heavy-ion facility. PII consists of an ECR ion source on a 350 KV platform injecting a very low velocity superconducting linac. The linac is composed of an independently-phased array of superconducting four-gap interdigital resonators which accelerate over a velocity range of .006 to .05c. In finished form, PII will be able to inject ions as heavy as uranium into the existing ATLAS linac. Although at the present time little more than 50% of the linac is operational, the indenpently-phased array is sufficiently flexible that ions in the lower half of the periodic table can be accelerated and injected into ATLAS. Results of recent operational experience will be discussed. 5 refs.

Book excerpt: The recently completed Positive-Ion Injector for the heavy-ion accelerator ATLAS is a replacement for the tandem injector of the present tandem-linac system. Unlike the tandem, the new injector provides ions from the full range of the periodic table. The concept for the new injector, which consists of an ECR ion source on a voltage platform coupled to a very-low-velocity superconducting linac, introduces technical problems and uncertainties that are well beyond those encountered previously for superconducting linacs. The solution to these problems and their relationship to performance are outlined, and experience in the operation of ATLAS with its new injector is discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Elemental Analysis by Particle Accelerators describes the theory, methodology, and applications for a wide variety of sensitive, non-destructive methods of analysis capable of both high selectivity and multielemental determinations. Specific methods discussed include radioactive methods, particle backscatter analysis, recoil techniques, and nuclear reaction analysis. The use of multielemental PIXE and PIGME analyses of "real world" thick samples in environmental studies, trace element applications in biology, and provenance studies in archaeology are also covered. The book is a useful reference for practicing specialists and an essential text for students.

Download or read book ATLAS Positive ion Injector Proposal written by and published by . This book was released on 1984 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The ATLAS facility will provide beams of heavy-ions through approximately mass 130. Energies provided will range from over 20 MeV/A for lighter ions down to approximately 5 MeV/A for mass 130. In discussions with our user group concerning future program needs, two major areas of focus emerged. The first was a desire to increase the beam intensities available by approximately a factor of ten beyond what is possible from our present negative-ion source and tandem injector for all ion species. The second was to obtain beams of at least 10 MeV/A energy for all possible masses through uranium. These features were desired without compromising the presnt qualities of the ATLAS facility: good beam quality, ease of operation, and continuous (DC) operation. The facility which has been proposed to address these goals consists of replacing the negative-ion injector and FN tandem with a positive-ion source and a superconducting linac of a new design which makes use of the high field gradients possible with superconducting structures. The positive-ion source proposed is an electron cyclotron resonance source mounted on a high-voltage platform, providing a 350-kV potential for preacceleration of the ions. This will produce, for example, uranium ions of 7 MeV with a velocity of .008c, assuming a charge state of 20/sup +/. The ions will be bunched in a two stage bunching system providing a pulsed beam with a time width of better than 0.4 ns for injection into the linac.
