for this subcontract was its patented PowerGuard building-integrated PV roofing tile. The objective of the subcontract over
its three-year duration was to continue the advancement of PowerLights PowerGuard manufacturing improvements in order
to reduce PowerGuard system costs, increase PowerGuard tile fabrication capability to 16-MW/year, and stimulate an increase
in manufacturing of PV laminates, within the USA, by 2-MW/year. PowerLight has also continued to address quality issues
by working on continuous improvement of tools and processes. Many aspects of factory operation have been improved, which
has helped reduce overall costs. Increased demand for PowerGuard, which has been generated in part by cost reduction
measures of the earlier phases of this project, has moved PowerLight into continuous production. This has allowed a shift from
a temporary work force hired for each job to a full time production staff, improving product quality and further cutting costs
by reducing the need for training.

During FY 2002, the Controls Advanced Research Turbine (CART) turbine and controller were developed and
commissioned. This included developing and checking out the protection and operational control systems. More than 50 hours
of data were collected in constant and variable-speed modes. A new strategy, which underwent limited testing on the machine,
was created for avoiding tower resonance. All the data from the checkout throughout the operational periods were organized,
archived, and backed up.

The need for ultra-sensitive actinide measurements continues to expand in the fields of environmental stewardship,
nuclear isotope forensics, radiobioassay and environmental research. We have developed a heavy isotope accelerator mass
spectrometry (AMS) system at Lawrence Livermore National Laboratorys Center for Accelerator Mass Spectrometry
(CAMS). The system was designed particularly for the measurement of actinide concentrations and isotopic ratios. A fast
isotope switching capability has been incorporated in the system, allowing flexibility in isotope selection and for the
quasi-continuous normalization to a reference isotope spike. The development of the heavy isotope system was undertaken
with particular interest in the measurement of environmental samples, including soils, sediments, waters, air filters, tissue
samples, and human urine. The high rejection of interferences, including molecular interferences, and low susceptibility to
matrix components, provided by the AMS technique are of particular relevance for such complex samples.

Hydraulic Activated Spreader Arm Aperture Generation System
Dec 2002; 13 pp.; In English
Report No.(s): AD-D020048; No Copyright; Avail: Issuing Activity (Defense Technical Information Center (DTIC))
A spreader arm aperture generation system for use with a towed array is provided. The spreader arm aperture generation
system broadly comprises a plurality of lines and a plurality of hydraulically activated, inflatable tubes for generating
horizontal and vertical separation among the lines. Each of the tubes is filled with seawater to a desired pressure to achieve
the desired horizontal and vertical line separation. Preferably, each of the tubes is formed from a high strength woven fabric.
