Semiclassical methods in chemical dynamics

Description: A general semiclassical (multidimensional WKB-type) approximation to quantum mechanics is reviewed. The principal feature of the approach is that it is able to incorporate the exact classical mechanics of the system and also the quantum principle of superposition. Applications to inelastic and reactive scattering, and to statistical mechanics and reaction rates are discussed. 13 refs.

Transient plasma estimation: a noise cancelling/identification approach

Description: The application of a noise cancelling technique to extract energy storage information from sensors occurring during fusion reactor experiments on the Tandem Mirror Experiment-Upgrade (TMX-U) at the Lawrence Livermore National Laboratory (LLNL) is examined. We show how this technique can be used to decrease the uncertainty in the corresponding sensor measurements used for diagnostics in both real-time and post-experimental environments. We analyze the performance of algorithm on the sensor data … more

Plant monitoring techniques and second generation designs

Description: Chemical and instrumental monitoring techniques suitable for geothermal use are described in a manner to relate them to plant operational problems and downtime avoidance. The use of these techniques permits the detection of scaling, the onset of scaling, corrosion loss, current corrosion rates and incipient heat exchanger failure. Conceptual advances are noted which simplify the research techniques to approaches that should be usable even in some low-capital well-head type power plants. 10 refs… more

Effects of slots/holes in disks on frequencies of TM/sub 01/ and EH/sub 11/ waves in the disk-loaded waveguide

Description: The increase in the BBU threshold current is very important for the high and medium energy electron linacs because of a larger operating current attainable or a smaller emittance available at certain operating current. For this purpose, many means can be used, among which the improvement in the accelerating structure itself is always fundamental. SLAC's three-meter long section is unique with truly constant gradient performance. The theoretical analyses and operating experiences at SLAC have in… more

Defect production and recovery in fcc metals irradiated at 4. 2 K

Description: Four fcc metals, Al, Cu, Ni, and Pt, have been irradiated at 4.2 K at the Livermore Rotating Target Neutron Source (RTNS-II) to fluences of 1 to 2 x 10/sup 21/ n/m/sup 2/. The sample resistivities were monitored during the irradiation. Following irradiation, the sample resistivities were monitored after isochronal anneals to 320 K. The initial resistivity damage rates for all four metals could be predicted to within +-10% from the results of irradiations in a pure fission spectrum by damage ene… more

SLC injector modeling

Description: The injector for the Stanford Linear Collider is being studied using the fully electromagnetic particle-in-cell program MASK. The program takes account of cylindrically symmetrical rf fields from the external source, as well as fields produced by the beam and dc magnetic fields. It calculates the radial and longitudinal motion of electrons and plots their positions in various planes in phase space. Bunching parameters can be optimized and insights into the bunching process and emittance growth … more

On-line model driven control of the SLC electron Damping Ring

Description: Model driven procedures have been used for control of the linac, beam transport lines and storage rings at SLAC. These procedures, based upon computer models of the machine lattice, are used for on-line calculation of the strengths of beam line components which yield desired lattice parameter values. They are also used for routine operation of the machine and for diagnosing and correcting errors of various types, as well as for aiding physicists in the acquisition and presentation of data.

Field-independent normalization of SSC Collider Ring costs

Description: The SSC Collider Ring represents the dominating cost element of the SSC project. The number of variables involved in optimizing the facility is very large so it is helpful to try to parameterize them in a way that allows a straightforward comparison of primary options. Cost information has been drawn from the Reference Designs Study supplemented by data from studies carried out by the Harza Engineering Company in Illinois. Various studies indicate that a 9' to 10' tunnel seems optimal from a co… more

Impacts of atmospheric tritium releases from solid waste storage areas

Description: Burial sites for low-level radioactive wastes are situated on the Oak Ridge National Laboratory (ORNL) reservation. Releases of radioactive material from these sites into the ground- and surface waters, thus affecting nearby residents, has long been a concern. Such releases are considered the primary pathway of concern from low-level burial sites in humid regions. However, recent publications indicate that the atmospheric pathway, through which tritiated water vapor, /sup 14/C, /sup 85/Kr, /sup… more

Commissioning and Operation of the Nuclear Physics Injector at SLAC

Description: The new Nuclear Physics Injector (NPI) approved for construction in October of 1983 was completed by September of 1984, and delivered short pulse beams for SPEAR ring checkout in mid-October. Long pulse beams of up to 1.6 microsecond length were also demonstrated. The paper describes the startup operation, reviews the performance characteristics, and discusses the beam transport optics used to deliver 1 to 4 GeV beams to nuclear physics experiments in End Station A.

Computer control of rf at SLAC

Description: The Stanford Linear Accelerator is presently upgraded for the SLAC Linear Collider project. The energy is to be increased from approximately 31 GeV to 50 GeV. Two electron beams and one positron beam are to be accelerated with high demands on the quality of the beams. The beam specifications are shown. To meet these specifications, all parameters influencing the beams have to be under tight control and continuous surveillance. This task is accomplished by a new computer system implemented at SL… more

Ion cyclotron heating experiments in PLT

Description: Results from ICRF heating experiments in the D-/sup 3/He minority regime on the PLT tokamak are reported. At the highest coupled rf power of 2.6 MW, a central ion temperature of 3.6 keV has been measured in plasmas with a central density of 5 x 10/sup 13/cm/sup -3/. The central value of the electron temperature is strongly modulated by the sawtooth internal relaxation and reaches values in excess of 3 keV.

Summary of modeling studies of the East Olkaria geothermal field, Kenya

Description: A detailed three-dimensional well-by-well model of the East Olkaria geothermal field in Kenya has been developed. The model matches reasonably well the flow rate and enthalpy data from all wells, as well as the overall pressure decline in the reservoir. The model is used to predict the generating capacity of the field, well decline, enthalpy behavior, the number of make-up wells needed and the effects of injection on well performance and overall reservoir depletion. 26 refs., 10 figs.
