Advanced fusion MHD power conversion using the CFAR (compact fusion advanced Rankine) cycle concept

Description: The CFAR (compact fusion advanced Rankine) cycle concept for a tokamak reactor involves the use of a high-temperature Rankine cycle in combination with microwave superheaters and nonequilibrium MHD disk generators to obtain a compact, low-capital-cost power conversion system which fits almost entirely within the reactor vault. The significant savings in the balance-of-plant costs are expected to result in much lower costs of electricity than previous concepts. This paper describes the unique fe… more

Initial Results in the Use of Prony Methods to Determine the Damping and Modal Composition of Power System Dynamic Response Signals.

Description: Prony analysis is an emerging method that extends Fourier analysis by directly estimating the frequency, damping, strength, and relative phase of modal components present in a given signal. This is precisely the kind of information that power system engineers would like to extract from transient stability program (TSP) simulations and from large-scale system tests or disturbances. A tool of this sort would be particularly valuable for TSP output analysis, where it promises to provide: parametri… more

Incorporation of a boundary condition to numerical solution of POISSON's equation

Description: Two-dimensional and axially-symmetric problems in electrostatics, magnetostatics or potential fluid flow frequently are solved numerically by means of relaxation techniques -- employing, for example, the finite-difference program POISSON. In many such problems, the ''sources'' (charges or currents, vorticity, and regions of permeable material) lie exclusively within a finite closed boundary curve and the relaxation process, in principle, then can be confined to the region interior to such a bou… more

A method for sizing sub-micron particles using small angle diffraction of soft x-rays

Description: The purpose of this work is to develop a method of sizing sub-micron particles using small-angle soft x-ray diffraction. Solid poly-styrene spheres of known sizes were used as scattering samples, with C-K..cap alpha.. (44.8/angstrom/) and V-L..cap alpha.. (24.3/angstrom/) radiation from a conventional x-ray source. Two devices were used to diffract the x-rays. One collimates the radiation using a series of pinholes immediately preceding the sample, and directs the unfocussed radiation onto film… more

Gallium arsenide digital integrated circuits for controlling SLAC CW-RF systems

Description: In order to fill the PEP and SPEAR storage rings with beams from the SLC linac and damping rings, precise control of the linac subharmonic buncher and the damping ring RF is required. Recently several companies have developed resettable GaAs master/slave D-type flip-flops which are capable of operating at frequencies of 3 GHz and higher. Using these digital devices as frequency dividers, one can phase shift the SLAC CW-RF systems to optimize the timing for filling the storage rings. We have eva… more

Intermediate energy heavy ions: An emerging multi-disciplinary research tool

Description: In the ten years that beams of intermediate energy ({approx}50 MeV/amu{le}E{le}{approx}2 GeV/amu) heavy ions (Z{le}92) have been available, an increasing number of new research areas have been opened up. Pioneering work at the Bevalac at the Lawrence Berkeley Laboratory, still the world's only source of the heaviest beams in this energy range, has led to the establishment of active programs in nuclear physics, atomic physics, cosmic ray physics, as well as biology and medicine, and industrial a… more

Inertial fusion results from Nova and implication for the future of ICF

Description: A key objective of the US Inertial Confinement Fusion Program is to obtain high yield (100-1000 MJ) implosions in a laboratory environment. This requires high grain from an inertial fusion target from a driver capable of delivering about 10 MJ. Recent results have been sufficiently encouraging that the US Department of Energy is planning for such a capability called the Laboratory Microfusion Facility (LMF). In the past two years, we have conducted implosion-related experiments with approximate… more

Summary of the laser working group

Description: The laser working group considered several options to deliver synchronized laser pulses of the required energy to the photocathode and laser triggered switches. These requirements actually decreased during the course of the workshop, and the values finally settled upon (<10 {mu}J in 100 fs at {approximately}250 nm for the photocathode and {approximately}20 mJ in 2 ps near either 250 nm or 1 {mu}m for the switches) were considered to be well within the state of the art. Some development work may… more

Coupling of precipitation/dissolution reactions to mass diffusion

Description: Coupling of precipitation/dissolution reactions to diffusive mass transport via porosity changes has been implemented in the computer program THCC, a simulator of reactive chemical transport. The coupling is accomplished without increasing the set of primary unknowns. Porosity is included explicitly in the transport equations and is tracked by accounting for changes of volumes of precipitates. The coupling prevents the volume of a precipitated solid from exceeding available pore volume. Results… more
