Plasma Separation Process: Betacell (BCELL) code: User's manual. [Bipolar barrier junction]

Description: The emergence of clearly defined applications for (small or large) amounts of long-life and reliable power sources has given the design and production of betavoltaic systems a new life. Moreover, because of the availability of the plasma separation program, (PSP) at TRW, it is now possible to separate the most desirable radioisotopes for betacell power generating devices. A computer code, named BCELL, has been developed to model the betavoltaic concept by utilizing the available up-to-date sour… more

Ventilating-air change rate versus particulate contaminant spread

Description: This study provides information on the spread of particulate contamination from glovebox leaks in plutonium manufacturing facilities, with emphasis on the effect of ventilating-air change rate on contaminated spread. A new, very sensitive aerosol tracer technique was developed to simulate plutonium aerosol leaks and its dispersion in a room. The tracer, a submicron aerosol of phloroglucinol, does not interfere with work activity and is detected by its ability to form ice crystals in a supercool… more

The present status of the LLNL Evaluated Charged Particle Library (ECPL)

Description: The present report is written with two purposes in mind: to summarize the charged-particle reactions that presently exist in Evaluated Charge Particle Library; and to list all of the low-Z charged-particle reactions for which data exist in the Livermore experimental data compilation. 2 tabs.

Transverse wake effects in an optical waveguide IFEL accelerator

Description: A recent proposal describes a project to build a short demonstration stage IFEL accelerator using as input beam the output of the Accelerator Test Facility high brightness linac (ATF) currently under construction at BNL. A second stage of the proposal involves the design and construction of a GeV IFEL accelerator. Both IFEL accelerators could be built using standard focussing as discussed in the proposal. While this is fairly natural in the short (60cm) demonstration accelerator, it requires mu… more

Thermal Regimes of Major Volcanic Centers: Magnetotelluric Constraints

Description: The focus of activity at this laboratory is on applying natural electromagnetic methods along with other geophysical techniques to studying the dynamical processes and thermal regimes associated with centers of major volcanic activity. We are presently emphasizing studies of the Long Valley/Mono Craters Volcanic Complex, the Cascades Volcanic Belt, and the Valles Caldera. This work addresses questions regarding geothermal energy, chemical transport of minerals in the crust, emplacement of econo… more

A new heavy-ion-beam driver model for the SAFIRE code

Description: The heavy-ion-beam driver model that was developed by McDonnell Douglas Astronautics Corporation as part of the Heavy Ion Fusion System Assessment study has been incorporated into the SAFIRE code. The model calculates the cost and performance of an induction linear accelerator and the beam transport systems required to deliver the beam to the fusion chamber. The results are used within the SAFIRE code for economic evaluation of inertial confinement fusion electric power plants. This report brie… more

High Pressure Source/Cryostat Relief Solutions

Description: This report addresses solutions to the potential problem of cryostat over pressurization by the nominal 65 psi MWAP LAr source dewar. Uncontrolled (by reason of failure) filling of a 15 psi MW AP cryostat by the LAr fill line could cause over pressurization by overwhelming the provided cryostat relief system. Three levels of protection against over pressurization by the source dewar are mentioned in this report; the reduced (operational) relief pressure, the source pressure regulator, and the L… more

CC Cryostat Vacuum Pumping Efficiency

Description: This report calculates the effect of the conductances of the pumping lines on the pumping speeds of the vacuum pumps being used to pump the inner vessel, and annular space, vacuum tight during the CC Cryostat testing. Effective pumping speeds were calculated for various values of pressure via the above stated formulas (see calculations). Conductances of valves, elbows, and tees were calculated with the help of ref. 1, and the volumes of the inner vessel and annular space were calculated wtth th… more

Ion dip spectroscopy of cold molecules and ions. Progress report and renewal proposal

Description: A research program is underway with the objective of developing techniques of high resolution multiphoton spectroscopy for selective, ultrasensitive molecular detection. Methods under study include various forms of ion dip spectroscopy and new methods of ion fragmentation spectroscopy. The studies are providing a new understanding of the fundamental spectroscopy and photophysics of large molecular ions. Dimer and cluster ions of polynuclear aromatics and related species are also being investiga… more

Cores from the Salton Sea scientific drilling program: Metamorphic reaction progress as a function of chemical and thermal environment: Final report

Description: The study investigated the downhole progressive metamorphism at the Salton Sea site by monitoring and evaluating discontinuous and continuous metamorphic reactions. The main emphasis was placed on: (1) the addition of petrographic, geochemical, and mineralogical data to the Salton Sea data base; (2) determination of downhole reactions; (3) evaluation of the progress of individual continuous reaction (epsilon) and the overall reaction progress (epsilon/sub T/) during the transition from one meta… more

Aviation Safety: FAA Near Midair Collision Reports

Description: This report discusses the minimum separation distance in a near midair collision report which the event must meet in order to be classified a "near miss." If a pilot of flight crew member subjectively believes that the near miss occurred, the report of that event is accepted by the Federal Aviation Administration (FAA) and counts as a near miss in the FAA data base regardless of the actual separation distance. While no proximity limits are placed on near midair collision reports, the agency doe… more
