Fifty years of nuclear fission: Nuclear data and measurements series

Description: This report is the written version of a colloquium first presented at Argonne National Laboratory in January 1989. The paper begins with an historical preamble about the events leading to the discovery of nuclear fission. This leads naturally to an account of early results and understanding of the fission phenomena. Some of the key concepts in the development of fission theory are then discussed. The main theme of this discussion is the topography of the fission barrier, in which the interplay of the liquid-drop model and nucleon shell effects lead to a wide range of fascinating phenomena encompassing metastable isomers, intermediate-structure effects in fission cross-sections, and large changes in fission product properties. It is shown how study of these changing effects and theoretical calculations of the potential energy of the deformed nucleus have led to broad qualitative understanding of the nature of the fission process. 54 refs., 35 figs.

Requirements and design of a high stable infrared free electron laser at LBL

Description: An infrared free electron laser (IRFEL) is being designed for the Chemical Dynamics Research Laboratory (CDRL) at LBL. The FEL is based on a 50 MeV RF linac operating in synchronization to the Advanced Light Source (ALS), and will produce intense (100 {mu}J per micropulse), narrow bandwidth (narrower than 0.1%) radiation between 3 {mu} and 50 {mu}. In the design, we pay particular attention to the FEL stability issues and require that the fluctuations in electron beam energy and in timing be less than 0.05% and 0.1 ps, respectively. The FEL spectrum can then be stabilized to about 10{sup {minus}3}, or if grating is used, to 10{sup {minus}4}. We discuss various sources of fluctuations in the gun, the bunchers and the accelerator sections, as well as the feedback and feedforward schemes to reduce these fluctuations. The accelerator structure is chosen to be of the side coupled, standing wave type for easier control. The beam transport is made isochronous to avoid the coupling between the energy and the timing fluctuations. 9 refs., 2 figs.

Obtaining gigaflop performance from particle simulation of plasmas

Description: In the numerical simulation of plasma phenomena there are two fundamental approaches that are generally followed. In the continuum approach one models the evolution of the fluid moment equations derived from the appropriate Boltzmann equation of the plasma. Alternatively, in the particle approach a large group of simulated charged particles are moved according to the self-consistent electromagnetic fields which partly depend on the charge and current densities of these same particles. Although the particle simulation method has been traditionally the more expensive of the two, it is much more capable of giving adequate account of many important kinetic phenomena. With the advent of the vector multiprocessor supercomputers, such as the Cray-2 or Cray Y-MP, we have learned to adapt particle simulation codes to exploit the parallel features of these machines. Yet, in spite of such developments, the particle simulation codes have remained much slower than the maximum machine speeds. We have investigated new techniques that further optimize these methods to bring the speeds of these particle simulations into the gigaflop range. Recent progress in this area suggests that the use of particle simulation methods will become competitive with the alternative fluid models especially when it is realized that gigaflop performance makes them much more affordable. 2 refs., 3 tabs.

Emission and transmission noise propagation in positron emission computed tomography

Description: Errors in positron emission computed tomograms are the result of noise propagated from three sources: (1) the statistical fluctuation in the positron coincidence events; (2) the statistical fluctuation in the incident transmission beam; and (3) the statistical fluctuation in the transmitted beam. The data for the transmission study in (2) and (3) are used to compensate for internal absorption of the distributed positron source. For the reconstruction of a circular phantom using the convolution algorithm, the percent root-mean-square uncertainty (%RMS) is related to the total measured positron events C and the incident photon flux per cm I/sub 0/. Our derivation of the %RMS uncertainty based on the propagation of errors yields a simple expression: %RMS = ..sqrt..K/sub 1//C + K/sub 2//I/sub 0/. The constants K/sub 1/ = 4.52 x 10/sup 8/ and K/sub 2/ = 1.48 x 10/sup 8/ were determined for a 20 cm diameter disc based on computer simulation. The projection data were analytically calculated with an attenuation coefficient ..mu.. = 0.0958 cm/sup -1/ for 140 angles between 0 and ..pi... Poisson noise was added to the positron coincidence events, the incident transmission events I/sub 0/, and the transmitted events. These results indicate that for a total number of incident transmission photons per cm of 2.0 x 10/sup 5/, the contrast resolution for a fixed spatial resolution is limited to 27% even with an infinite number of emission events. For a total of 10/sup 6/ emission events the contrast resolution is 34%.

Lower-hybrid current drive with opposing ohmic drive on PLT

Description: Two distinct conditions where the rf phase velocity is directed opposite to the ohmically induced electron drift have been studied experimentally: (1) rf current ramp-up (f/sub p/ > 0), where an induced electric field opposes the current increase; (2) rf current ramp-down, where waves are launched opposite the electron drift direction for a decaying plasma current. The time behavior of the electron tail is inferred from hard x-ray (30 to 750 keV) emission as a function of angle to B. In cases (1) and (2) we find that the emission amplitude in the reverse (opposite the LH phase velocity) direction increases throughout the rf pulse, while it is constant in the forward direction. This increase indicates that some high energy electrons are accelerated or are even running away in the direction opposite to the main rf produced tail. It also indicates for case (1) that the electric field in the plasma center has been reversed by the rf current drive.

Results of the radiological survey at 113 Avenue E, Lodi, New Jersey (LJ081)

Description: Maywood Chemical Works (MCW) of Maywood, New Jersey, generated process wastes and residues associated with the production and refining of thorium and thorium compounds from monazite ores from 1916 to 1956. MCW supplied rare earth metals and thorium compounds to the Atomic Energy Commission and various other government agencies from the late 1940s to the mid-1950s. Area residents used the sandlike waste from this thorium extraction process mixed with tea and cocoa leaves as mulch in their yards. Some of these contaminated wastes were also eroded from the site into Lodi Brook. At the request of the US Department of Energy (DOE), a group from Oak Ridge National Laboratory conducts investigative radiological surveys of properties in the vicinity of MCW to determine whether a property is contaminated with radioactive residues, principally /sup 232/Th, derived from the MCW site. The survey typically includes direct measurement of gamma radiation levels and soil sampling for radionuclide analyses. The survey of this site, 113 Avenue E, Lodi, New Jersey (LJ081), was conducted during 1988. Results of the survey demonstrated radionuclide concentrations in excess of the DOE Formerly Utilized Sites Remedial Action Program criteria. The radionuclide distributions are typical of the type of material originating from the MCW site. 5 refs, 2 figs., 3 tabs.

Decision analysis for evaluating and ranking small solar thermal power system technologies. Volume I. A brief introduction to multiattribute decision analysis

Description: Multiattribute decision analysis is a methodology for providing information to a decision maker for comparing and selecting between complex alternatives. A brief introduction to the principal concepts of the Keeney and Raiffa approach to multiattribute decision analysis is presented. The concepts of decision alternatives, outcomes, objectives, attributes and their states, attribute utility functions, and the necessary independence properties for the attribute states to be aggregated into a numerical representation of the preferences of the decision maker for the outcomes and the decision alternatives are presented. 50 references.
