FY00 LDRD Final Report High Power IFE Driver Component Development 00-SI-009
We have begun building the ''Mercury'' laser system as the first in a series of new generation diode-pumped solid-state lasers for target physics research. Mercury will integrate three key technologies: diodes, crystals, and gas cooling, within a unique laser architecture that is scalable to kilojoule and megajoule energy levels for fusion energy applications. The primary near-term performance goals include 10% electrical efficiencies at 10 Hz and 100 J with a 2-10 ns pulse length at 1.047 {micro}m wavelength. Currently, this review concentrates on the critical development and production of Yb:S-FAP crystals. After solving many defect issues that can be present in the crystals, reproducibility is the final issue that needs to be resolved. We have enlisted the help of national experts and have strongly integrated two capable commercial crystal growth companies (Litton-Airton/Synoptics and Scientific Materials) into the effort, and have solicited the advice of Robert Morris (retired from Allied Signal), a recognized international expert in high temperature oxide growth.

The incorporation of GIS in radiological transportation accident consequence assessments.
Potential impacts of transportation accidents must be addressed in documents prepared under the National Environmental Protection Act (NEPA) as amended or in other environmental-related documents when the transportation of radioactive materials is considered. Estimating the potential human health consequences from the release and dispersion of radioactive materials following such an accident involves a number of interrelated computational models and a variety of input parameters. The RISKIND radiological transportation risk computer program [1] was developed to provide these types of estimates for local scenarios. However, it is often difficult to gain a full understanding of the initial problem and consequences by looking solely at numerical input and tables of results. To permit better-informed decisions, visualization of the site-specific geographic area and the potential spread of contamination can provide greater understanding. Thus, a geographic information system (GIS) component has been integrated with RISKIND to provide visualization capabilities as well as site-specific and computational benefits.

CP VIOLATION IN K DECAY FROM LATTICE QCD, RIKEN BNL RESEARCH CENTER, RBRC AND PARTICLE PHYSICS SEMINAR, BROOKHAVEN NATIONAL LABORATORY, UPTON, N.Y., JULY 26, 2001.
The entire history of the discoveries of K{sub L}{sup o} and violations of T and CP began at Brookhaven. It is most appropriate for us to hold today's special seminar on CP Violation in K decay in this laboratory. Forty-five years ago, in the same paper on parity nonconservation, it was also pointed out that there is no proof of T symmetry in the weak interaction, nor of C invariance. That paper was submitted to the Physical Review (then, also located at BNL) on June 22, 1956. A month later, Lederman and his collaborators discovered a long-lived neutral V particle (now called K{sub L}{sup o}) at the Cosmotron using the cloud chamber. This discovery was presented as a rigorous proof of C symmetry. In the same summer at Brookhaven, in collaboration with Oehme and Yang, I did the analysis on the neutral kaon system, assuming T, C and CP violations (but based on CPT symmetry). In that work, the two non-orthogonal eigen-states {psi}{sub +} and {psi}{sub -} (now K{sub S}{sup o} and K{sub L}{sup o}) were characterized by a non-orthogonality parameter {alpha} ({approx_equal} 2 Re{epsilon} in today's notation), which was shown to be small, because of unitarity. We then went …

Prediction of Gas Injection Performance for Heterogeneous Reservoirs
This report was an integrated study of the physics and chemistry affecting gas injection, from the pore scale to the field scale, and involved theoretical analysis, laboratory experiments and numerical simulation. Specifically, advances were made on streamline-based simulation, analytical solutions to 1D compositional displacements, and modeling and experimental measures of three-phase flow.

Degradation of multibunch luminosity in a linear collider due to cumulative beam breakup
Beam-excited transverse wakes in accelerating radiofrequency structures will influence the transverse offsets of each bunch in a multibunch train, causing the projected emittance of the bunch train to grow. An analytic theory of this phenomenon that includes the mitigating influence of a correlated energy spread across the bunch train was recently devised and applied to electron-positron linear colliders. We use the results of this theory to estimate analytically the associated degradation of multibunch luminosity in terms of top-level parameters for the two beams, the two accelerators, and the final-focus system. Then we compare the estimates with results from GUINEA-PIG, a code that includes the detailed physics of beam-beam interactions.

Scanning tunneling microscopy and spectroscopy of ceramic interfaces. Technical report to the Department of Energy, Office of Basic Energy Sciences
This document reports advances made on the Penn DOE project focused on using scanning probe measurements at individual interfaces to relate nanometer scale property variation to behavior in ceramic systems. The report body summarizes annual technical accomplishments. (The details are provided in papers referenced in the appendix.) Related collaborative interactions are described, after which the project productivity is reported in terms of human resource development and publications.

Speckle Reduction for LIDAR Using Optical Phase Conjugation
Remote detection of chemicals using LIDAR (Light Detection and Ranging) utilizing DIAL (Differential Absorption LIDAR) is now a standard detection technique for both military and civilian activities. We have developed a novel nonlinear optical phase conjugation system that can reduce the effects of speckle noise and atmospheric turbulence on DIAL remote detection systems. We have shown numerically and experimentally that it is possible to increase the signal-to-noise (S/N) ratio for LIDAR systems under certain conditions using optical phase conjugation. This increase in S/N can result in more accurate detection of chemical effluents while simultaneously reducing the time necessary to acquire this information.
