High-temperature borate liquids: physical properties of glass-forming compositions

Description: Several experimental routes can be used to develop a better understanding of the polymeric constitution (polyanionic and/or polyhedral distribution) of borate, germanate, and silicate glasses. Spectral, chemical, physical-chemical, and mechanical property information can be determined directly for the glass compositions of interest. Generally, only physical-chemical information is readily accessible for the corresponding high temperature liquids. It will be shown that information on each state … more

Preliminary design and analysis of recovery of lithium from brine with the use of a selective extractant

Description: Lithium requirements for battery and controlled thermonuclear fusion reactor uses in the next few decades may exceed the current availability of the mineral and brine reserves. It is thus prudent to search for new reserves and resources to satisfy these and other lithium applications in the future. It has been reported that the lithium content of Smackover oilfield waters ranges in order of 100--500 mg/l, and thus could represent a substantial reserve. A method is proposed to extract lithium fr… more

Inelastic Neutron Cross Sections on Nuclei at FNAL

Description: Direct experimental measurements of the inelastic cross sections of neutrons on a variety of nuclei have been made at Fermi lab over the energy range from 50 to 350 GeV. These data may be used, together with nucleon-nucleon total cross sections measured through the same energy range, to justify and verify the interpretation of cosmic ray data on interaction mean free paths in air or iron in terms of nucleon-nucleon total cross sections at much higher energies.

Methods for siting small wind machines

Description: The question of siting wind energy conversion systems (WECS) represents a balance between the economic, technical and social values of the user and the local citizens. The technical issues are discussed. Before addressing the technical siting issues, as well as the social and economic ones, a determination of the potential user, the application of the WECS, and the geographical location of the installation must be made. Once these three determinations have been made, the meteorological and topo… more

Parameters of a field-reversed mirror reactor

Description: Computations have been made of the parameters of a neutral-beam driven, field-reversed mirror reactor as a function of beam injection energy. Q values of 4 to 5 and a fusion power of 10 to 50 MW per cell are found at beam energies of 200 to 500 keV. Cost estimates indicate a direct capital cost of less than $1000/kW/sub e/ for multicell versions of the reactor.

SHIVA laser: nearing completion

Description: Construction of the Shiva laser system is nearing completion. This laser will be operating in fall 1977 and will produce over 20 terawatts of focusable power in a subnanosecond pulse. Fusion experiments will begin early in 1978. It is anticipated that thermonuclear energy release equal to one percent that of the incident light energy will be achieved with sub-millimeter deuterium-tritium targets. From other experiments densities in excess of a thousand times that of liquid are also expected.

Evolution of the amplitude distribution function for a beam subjected to stochastic cooling

Description: The suggestion of S. van der Meer for stochastic cooling or feedback damping of a circulating charged particle beam offers promise of increasing the luminosity of a storage ring and may be a particularly attractive technique if antiprotons are to be employed as one of the beams in such a device. The original report of van der Meer considered the repeated use of a kicker to suppress the transverse phase-space displacement of the centroid of a group of particles detected at a pick-up station situ… more

Electron energy and space charge calculations in reflex diodes

Description: Previously reported Monte Carlo code calculations of the electron energy distributions and the consequent reflex triode characteristics will be presented for two different anode designs. In addition, a generalized formulation of Poisson's equation will be used to examine the virtual cathode side of a reflex diode. The familiar ''resonance'' solution for the reflex triode is again found, but with a different physical interpretation. In the former case the current diverges, but in the virtual cat… more

Role of the Pauli principle in pion--nucleus scattering. [Many-body theory with propagators, self-energy]

Description: The role of the Pauli principle in pion-nucleus scattering is studied using many-body theory with propagators. The objective is to calculate the pion self energy in the nucleus from an effective ..pi..N amplitude which is density dependent. It is concluded that the Pauli effect on the optical potential is small (5% level), that first order hole line expansion for the effective amplitude is inappropriate, and that particle and hole propagation must be treated symmetrically. 2 references.

Rydberg series in the lanthanides and actinides observed by stepwise laser excitation

Description: The techniques of stepwise laser excitation were applied to obtain Ryberg series in the lanthanides and in uranium. The methods employed circumvent many of the experimental difficulties inherent in conventional absorption spectrosopy of these heavy atoms with very complex spectra. The Rydberg series observed have allowed the determination of accurate ionization limits. The values in eV are: Ce, 5.5387(4);Nd, 5.5250(6); Sm, 5.6437(10); Eu, 5.6704(3); Gd, 6.1502(6); Tb, 5.8639(6); Dy, 5.9390(6); … more
