Proceedings of the Workshop on Geothermal Reservoir Engineering: 1977
The Third Workshop on Geothermal Reservoir Engineering convened at Stanford University on December 14, 1977, with 104 attendees from six nations. In keeping with the recommendations expressed by the participants at the Second Workshop, the format of the Workshop was retained, with three days of technical sessions devoted to reservoir physics, well and reservoir testing, field development, and mathematical modeling of geothermal reservoirs. The program presented 33 technical papers, summaries of which are included in these Proceedings. Although the format of the Workshop has remained constant, it is clear from a perusal of the Table of Contents that considerable advances have occurred in all phases of geothermal reservoir engineering over the past three years. Greater understanding of reservoir physics and mathematical representations of vapor-dominated and liquid-dominated reservoirs are evident; new techniques for their analysis are being developed, and significant field data from a number of newer reservoirs are analyzed. The objectives of these workshops have been to bring together researchers active in the various physical and mathematical disciplines comprising the field of geothermal reservoir engineering, to give the participants a forum for review of progress and exchange of new ideas in this rapidly developing field, and to summarize the effective …

High-energy glass lasers
In order to investigate intense pulse propagation phenomena, as well as problems in laser and system design, a prototype single chain laser called CYCLOPS was constructed. This laser employs a 20-cm clear aperture disk amplifier in its final stage and produces a terawatt pulse whose brightness exceeds 10$sup 18$ watts/cm$sup 2$-ster. The CYCLOPS system is summarized and aspects of nonlinear propagation phenomena that are currently being addressed are discussed. (MOW)

Two methods of space-time energy densification
With a view to the goal of net energy production from a DT microexplosion, two ideas (methods) are studied through which (separately or in combination) energy may be ''concentrated'' into a small volume and short period of time--the so-called space-time energy densification or compression. The advantages and disadvantages of lasers and relativistic electron-beam (E-beam) machines as the sources of such energy are studied and the amplification of laser pulses as a key factor in energy compression is discussed. The pulse length of present relativistic E-beam machines is the most serious limitation of this pulsed-power source. The first energy-compression idea discussed is the reasonably efficient production of short-duration, high-current relativistic electron pulses by the self interruption and restrike of a current in a plasma pinch due to the rapid onset of strong turbulence. A 1-MJ plasma focus based on this method is nearing completion at this Laboratory. The second energy- compression idea is based on laser-pulse production through the parametric amplification of a self-similar or solitary wave pulse, for which analogs can be found in other wave processes. Specifically, the second energy-compression idea is a proposal for parametric amplification of a solitary, transverse magnetic pulse in a coaxial cavity with a …

Lawrence Livermore Laser Fusion Program: a status report
The Laser Fusion Program at the Lawrence Livermore Laboratory is presently emerging from a three-year period of intensive development of the tools required for significant DT implosion experiments of continuously increasing scale. These diverse tools include target design codes, sophisticated target fabrication techniques, radically new diagnostics instrumentation, high peak- power-high brightness laser technology, and fully integrated laser-target- diagnostic irradiation facilities. These tools have recently led to the successful production of neutrons from compressed DT-containing targets together with a wealth of correlating plasma physics data. The current status of major program activities at LLL will be reviewed and major future milestones will be projected. (auth)

Neutron time-of-flight spectrometer for laser-fusion experiments
The basic concept of a time-of-flight spectrometer is illustrated. The spectrometer described can measure 14.1-MeV neutrons coming directly from the D-T plasma and also neutrons scattered by the air or ground or other structures within the vicinity of the flight path. (MOW)

Analysis of the ball-plate laser fusion target experiments
Two dimensional computer simulation results of the two exploding pusher ball-plate targets are in approximate agreement with the experimental space and time integrated x-ray spectra, x-ray microscope data, neutron yields, and laser energy absorptions. Three parameters were used to characterize the laser absorption due to plasma instabilities. Two dumpall parameters were used to model the energy absorption and a single variable was used to define the electron temperature. The values, as well as the selection procedure for these parameters are discussed. (auth)

X-ray microscopy of laser fusion targets in four energy bands from 0.7 to 4.0 keV
A grazing x-ray microscope was shown to be able to photograph the x-ray emission from laser-produced plasmas between 0.8 and 4.0 keV with a spatial resolution of approximately 3 microns. The calibration of the x-ray mirror energy response functions and the x-ray film allow absolute measurements of the spatial and spectral distribution of the x-ray emission from laser fusion targets.

Physics of gas cooled reactors
From meeting on new developments in reactor physics and shieiding calculations; Lake Kiamesha, New York, USA (12 Sep The temperature coefficient of the HTOR is composed of a strong negative Doppler coefficient and a positive moderator coefficient, the net effect being about -10 x 10/sup -5// deg C at operating temperature. the positive moderator coefficient is a result of the absence of significant density coefficients and the nuclear characteristics of U- 233. In addition, selected iission products, principally Xe-135, contribute positive components to the temperature coefficient. Current estimates of the value of the temperature coefficient in the HTGR are presented along with recent experimental data pertinent to the subject. (11 references) (auth)

Atomic number dependence of hadron production at large transverse momentum in 300 GeV proton--nucleus collisions
In an experiment at the Fermi National Accelerator Laboratory we have compared the production of large transverse momentum hadrons from targets of W, Ti, and Be bombarded by 300 GeV protons. The hadron yields were measured at 90{sup o} in the proton-nucleon c.m. system with a magnetic spectrometer equipped with 2 Cerenkov counters and a hadron calorimeter. The production cross-sections have a dependence on the atomic number A that grows with P{sub perpendicular}, eventually leveling off proportional to A{sup1.1}.
