3D Particle Simulation of Beams Using the Warp Code: Transport Around Bends
WARP is a discrete-particle simulation program which was developed for studies of space charge dominated ion beams. It combines features of an accelerator code and a particle-in-cell plasma simulation. The code architecture, and techniques employed to enhance efficiency, are briefly described. Current applications are reviewed. In this paper we emphasize the physics of transport of three-dimensional beams around bends. We present a simple bent-beam PIC algorithm. Using this model, we have followed a long, thin beam around a bend in a simple racetrack system (assuming straight-pipe self-fields). Results on beam dynamics are presented; no transverse emittance growth (at mid-pulse) is observed. 11 refs., 5 figs.

3D simulations of axially confined heavy ion beams in round and square pipes
We have been using the 3d PIC code WARP6 to model the behavior of beams in a heavy ion induction accelerator; such linacs are candidates for an ICF driver. Improvements have been added to the code to model an axially confined beam using comoving axial electric fields to simulate the confining ears'' applied to the accelerating pulses in a real system. We have also added a facility for modeling a beam in a round pipe, applying a capacity matrix to each axial Fourier mode in turn. These additions are described along with results, such as the effect of pipe shape on the beam quality degradation from quadrupole misalignments. 4 refs., 6 figs., 1 tab.

Ammonium silicate diagenesis and its influence on the interpretation of fixed-ammonium anomalies as an exploration tool
The study of nitrogen (NH{sub 4}{sup +}) diagenesis associated with hydrocarbon occurrences is intended to aid in predicting favorable areas of petroleum exploration and recovery by establishing a better understanding of the interaction of organic maturation products with clastic sedimentary sequences. This research has indicated that fixed-NH{sub 4} in clays preserves anomalous NH{sub 4}{sup +} abundances, thus recording a significant reaction in the maturation of hydrocarbons which correlates with the oil window. Fixed-NH{sub 4} concentrations are independent of total organic carbon content, but increase with organic maturity in source rocks (up to T{approx}140 C). The authors have found anomalously high fixed-NH{sub 4} concentrations in oil and gas reservoirs, and in sandstones that may have acted as migration conduits for a nearby oilfield. The remainder of the project period will be spent completing publications, and finalizing the interpretation of results on fixed-NH{sub 4} in the Salton Sea (SSDP) and Monterey Fm. The data that authors have collected from these areas will allow them to examine the effect of high temperatures and high-N organic matter (prevalent on the west coast) on levels of NH{sub 4}-fixation. The authors will also develop some preliminary ideas on the mechanism of NH{sub 4}{sup +} oxidation responsible …

Design and Analysis of RTGs for CRAF and Cassini Missions
This report consists of two parts. Part 1 describes the development of novel analytical methods needed to predict the BOM performance and the subsequent performance degradation of the mutually obstructed RTGs for the CRAF and Cassini missions. Part II applies those methods to the two missions, presents the resultant predictions, and discusses their programmatic implications. The results indicate that JPL's original power demand goals could have been met with two standard GPHS RTGs for each mission. But subsequently JPL significantly increased both the power level and the mission duration for both missions, so that they can no longer by met by two standard RTGs. The resultant power gap must be closed either by reducing JPL's power demand (e.g., by decreasing contingency reserves) and/or by increasing the power system's output. One way under active consideration which more than meets the system power goal would be the addition of a third RTG for each mission. However, the author concluded that it may be possible to meet or closely approach the CRAF power demand goals with just two RTGs by relatively modest modification of their design and/or operating conditions. To explore that possibility, the effect of various modifications - either singly or in …
