Ion source studies at the ORNL ECR source facility

Description: Using high resolution magnetic analysis, we have measured energy spreads of Ar/sup +q/ (1 < q < 12) ion beams extracted from the ORNL ECR ion source under a number of different ECR plasma conditions. The measured energy spreads for the different charge states fall in the range 8 to 20 eV per charge and are all roughly proportional to the ion charge. In addition, we have used a combination of magnetic and electrostatic analysis to investigate the high charge state tail of the extracted Ar/sup +q… more

Operation of the ORNL ECR (Electron Cyclotron Resonance) source

Description: The ORNL ECR multicharged ion source, dedicated for studying the atomic physics interactions of multicharged ions with atoms, ions, electrons, and surfaces has been in operation since 1984. High charge state ion beams ranging from fully stripped light ions (up to Ne) to up to 40% stripped heavy ions (A approx. 200) have bee produced. Ion beams of the metallic elements developed to date include Cr, Fe, Ni, Ta, and Au, and are obtained by the use of a solid feed technique.

AN APPLICATION OF GAME THEORY TO SPECIAL WEAPONS EVALUATION

Description: A metbed was introduced for combining the techniues of classical Lanchester theory of combat with those of game theory toward the end of selecting optimal strategies in combat with special weapons. In the application of this method to the example in which only the defender had atomic weapons,. it was showm that the attacker always chose either to disperse his troops the maximum amount or not to disperse his troops at all. The defender always chose to employ a mixed strategy consisting of the we… more

Radiological analysis of hypothetical accidents by computer

Description: The radiological analyses of extreme hypothetical accidents were performed almost wholly by computer techniques. Major analytical codes used were RIBD, CACECO, SPRAY, HAA, and COMRADEX. This paper describes the analyses, the modeling techniques, and transition programs that edited data output from one code into a form suitable for input to another. Although not sacrificing a conservative stance, the degree of realism afforded by these analyses shows that the projected consequences could be acce… more

Develop and Test an Internally Cooled, Cabled Superconductor (ICCS) for Large Scale MHD Magnets

Description: The work conducted under DOE/PETC Contract DE-AC22-84PC70512 has included four principal tasks, (1) development of a Design Requirements Definition for a retrofit MHD magnet system, (2) analysis of an internally cooled, cabled superconductor (ICCS) to use in that design, (3) design of an experiment to test a subscale version of that conductor, which is a NbTi, copper stabilized superconductor, and (4) proof-of-concept testing of the conductor. The program was carried forth through the third tas… more

Evaluation models and their influence on radiological consequences of hypothetical accidents in FFTF

Description: The influence of radiological evaluation models and assumptions on the off-site consequences of hypothetical core disruptive accidents is examined. The effects of initial source term, time of containment venting, meteorology, biological dose model, and aerosol fallout have been included. The analyses were based on two postulated scenarios of a severe hypothetical reactor vessel melt-through accident for 400 MW(t) fast reactor. Within each accident scenario, the results show that, although other… more

DC CICC retrofit magnet preliminary design, protection analysis and software development

Description: In the past few years, several computer codes have been written for the purpose of analyzing transient recovery and quench in internally-cooled cable-in-conduit superconductors (ICCS). These codes all include a transient, compressible helium flow model. They differ in the dimensionality'' of the models, ranging from one- to three-dimensional finite element modeling of thermal conduction. The code used in this study, Wong's CICC, is a 1-{1/2} D code that models thermal conduction through the ins… more

DC CICC retrofit magnet preliminary design, protection analysis and software development. Quarterly progress report, [September--November 1991]

Description: In the past few years, several computer codes have been written for the purpose of analyzing transient recovery and quench in internally-cooled cable-in-conduit superconductors (ICCS). These codes all include a transient, compressible helium flow model. They differ in the ``dimensionality`` of the models, ranging from one- to three-dimensional finite element modeling of thermal conduction. The code used in this study, Wong`s CICC, is a 1-{1/2} D code that models thermal conduction through the i… more

FFTF containment of hypothetical accidents

Description: The FFTF facility was evaluated for the consequences of an HCDA followed by failure of in-vessel post-accident heat removal, reactor vessel melt-through, and release of core debris and sodium coolant to the reactor cavity. Two cases are presented based on parameters considered to represent upper limits for rates of chemical and thermal attack of the reactor cavity concrete containment structure. The reactor containment building temperature, pressure, and leak rate histories were computed with t… more

ECR-based atomic collision physics research at ORNL

Description: After a brief summary of the present capability and configuration of the ORNL Multicharged Ion Research Facility (MIRF), and of upcoming upgrades and expansions, the presently on-line atomic collisions experiments are described. In the process, the utility of intense, cw ion beams extracted from ECR ion sources for low-signal rate experiments is illustrated.

Collisions of highly charged ions with electrons, atoms and surfaces

Description: At the Oak Ridge Multicharged Ion Source Facility, an experimental atomic collisions physics program is centered around a recently upgraded Electron Cyclotron Resonance (ECR) multicharged ion source. The 10 GHz CAPRICE source has been in operation since October 22, 1992, and has provided more intense, higher charge ion beams than our previous ECR ion source. Intense metallic beams have recently become available with the installation of a metallic oven on the source. In addition to measurements … more
