Future directions in intermediate energy heavy ion physics. A proposed expansion of the Holifield Facility
Abstract
A proposal is presented for a major accelerator addition to the Holifield Heavy Ion Research Facility. The expanded facility will provide ion beams of mass 1 to 238 amu with a combination of energy, intensity, momentum resolution, and beam quality not currently available at any other facility in North America. The physics motivation for such an addition is discussed, and involves physics dominated by meson-exchange forces, Coulomb-force dominated physics, and possibly a regime where the quark and gluon degrees of freedom are significant. The physics research would include topics in atomic and interdisciplinary areas as well as nuclear physics. Some remarks are made on the merits of Oak Ridge as a site for this facility, placing the proposal in some historical perspective. The accelerator system is then described, giving the required beam properties, and the parameters of the synchrotron ring components, injection, ring magnets, RF systems, vacuum system, and electron cooling system and stochastic cooling system requirements. Also described are such facilities as buildings, beam transport and shielding, and experimental facilities, including target areas. (LEW)

The primary objective of this handbook is to provide information for those who plan to carry out research programs at the Holifield Heavy Ion Research Facility (HHIRF) at Oak Ridge National Laboratory. The accelerator systems and experimental apparatus available are described. The mechanism for obtaining accelerator time and the responsibilities of those users who are granted accelerator time are described. The names and phone numbers of ORNL personnel to call for information about specific areas are given. (LEW)

(Recent developments at the Holifield Heavy Ion Research Facility)
The traveler attended the European Particle Accelerator Conference in Nice, France, on June 12--16, 1990, and presented the paper Recent Developments at the Holifield Heavy Ion Research Facility.'' All aspects of European accelerator operation, construction, and development were discussed at this conference. It seemed as if very few new European accelerator projects were under serious study. The traveler also visited the ECR ion source group at Grenoble, France, and found them very willing to participate in the development of an ECR source for the HHIRF tandem accelerator. The MIMAS ring at Saclay, France, is very similar to the HISTRAP proposalmore » -
Sulfur hexafluoride transfer and storage system of the Holifield Heavy Ion Research Facility: some thermodynamic properties
The transfer of SF/sub 6/ insulating gas from the 25 MV accelerator pressure vessel (volume = 80,000 ft/sup 3/) into liquid storage tanks (volume = 6,000 ft/sup 3/) is accomplished by means of two three-stage piston compressors operating in parallel. Gas from the first and second compression stages is passed through heat exchangers prior to injection into subsequent stages while gas from the third stage is cooled and/or liquified by a third exchanger/condenser. Tabulated thermodynamic data were used in calculating the SF/sub 6/ transfer rate, stage compression ratios and heat transfer rates as a function of the fraction of themore » -
Holifield Heavy Ion Research Facility computer handbook, 1987
This document is intended to acquaint a prospective user with the Holifield Heavy Ion Research Facility (HHIRF) data acquisition/analysis computer facility. The HHIRF data acquisition/analysis computer facility is comprised of 3 CONCURRENT 3230 computers and peripherals. These are 32-bit word machines, each 16 megabytes of semiconductor memory. Peripherals on each system include: three or more disk drives, 2 or 3 TELEX (1600/6450 bpi) tape drives, a line printer, several CPU-shared TRILOG printer/plotters, a CPU-shared TEK-4696 color Ink-Jet plotter, several graphics terminals, a number of VDT terminals and CAMAC interfaces. -
Scattering chamber for the Holifield Heavy Ion Research Facility
A conceptual design is presented for a 62-in.-diam. general purpose scattering chamber to be used for nuclear research with heavy ions. The detector rotation mechanism is based on large diameter (approx. 58 in.) peripherally driven rings. This leaves the central region open for detectors and other apparatus and permits the use of a perpendicular ring for rotating a detector out of the reaction plane. A precision target slide with provisions for removing the entire slide under vacuum is part of the design. Access and viewing ports on the dished top and in the reaction plane will be provided.
