Application of microfabrication technology to thermionic energy conversion. Progress report 4, 1 May 1980 to 31 July 1980

Description: Two applications of microfabrication technology to thermionic converters have been investigated theoretically. The first is a novel method of maintaining micron or submicron spacings over large areas (>1 cm/sup 2/), using metals of different expansion coefficients to eliminate the shear stresses on the insulating pillars separating the electrodes. The second uses low-voltage field-emission sources to create ions in a large (approx. 1 mm) interelectrode gap for space charge neutralization. The t… more

Shawnee test program: TVA Shawnee Test Facility. Technical progress report, April 6-May 6, 1981

Description: The test obtective for April was to evaluate sodium thiosulfate in limestone scrubber slurry as inhibitor of sulfite oxidation. The resulting effect on saturation levels of calcium sulfate (CaSO/sub 4/.2 H/sub 2/O; gypsum) and scaling in the system was of prime importance. As an antioxidant, S/sub 2/O/sub 3//sup =/ functions as a scale inhibitor by reducing SO/sub 4//sup =/, a known scale former. To meet the test objective, the scrubber was operated in a scaling mode as a base case; finally, th… more

(Fission product transport experiments (HFR-B1))

Description: Travel to the JRC Petten was for the purpose of discussing the HFR-B1 experiment and post irradiation activities. Technical assessment of the experiment strongly supports the concept of enhanced fission gas release at temperatures above 1100{degree}C, the extensive release of stored fission gas at water vapor levels postulated in accident scenarios, an increase in the steady-state fission gas release under hydrolyzing conditions, and an increase in gas release during thermal cycling.

(Restriction of virus infection by plants: Annual report, 1986)

Description: This research concerns the strong resistance, or even immunity, against a specific virus that is exhibited by one or a few lines of a plant species, in contrast to the general susceptibility of most lines of that species. The contrast between the reactions to virus inoculation of different lines of one species implies that a single gene or a very few genes may mediate the resistance or immunity. The prospects for isolating, studying and transferring such a gene should be good for a system with … more

Raising the acceptance of the AP2-line

Description: The 120 GeV Main Ring proton beam collides with the target at the end of the AP-1 line and creates antiprotons and other secondary particles. The AP-2 line transfers the negative particles from the target to the Debuncher. To provide a bigger antiproton stack size in the Accumulator, both the Debuncher as well as the AP-2 line acceptance have to be raised. This is a proposal for the improvement of the AP-2 line acceptance. The first part of the memo presents an acceptance examination of the exi… more

Energy savings through the use of an improved aluminum reduction-cell cathode. Technical progress report, April 1, 1980-June 30, 1980

Description: Goal is to develop a Hall cell cathode, which will reduce the specific energy consumption of existing commercial cells by 20 to 25%. Basis of the improvement is the utilization of titanium diboride (TiB/sub 2/), a material that is wetted by molten aluminum, as the cell cathode. This provides a stable cathode surface, thereby allowing the cell to be operated at a smaller anode-cathode distance (ACD). Energy savings arise as a result of reduced resistive losses through the cryolite electrolyte. T… more

Model of current enhancement at high pressure

Description: A model is proposed to account for the phenomenon of net current enhancement at high pressures recently observed on the Experimental Test Accelerator. The proposed mechanism involves energetic secondary electrons (delta rays) which are pushed forward by the self-magnetic field of the electron beam. For high current beams, the forward delta ray current can build up to a significant fraction of the beam current. Analytic calculations of the steady-state solution as well as the rate of buildup of … more
