Mark-1 Cryostat Status Report Q1 and Q2, FY03

Description: The Mark 1 now has a completion date goal of mid-FY05 . The original concept for the Mark-1 cryogenics was based upon a liquid helium (LHe) reservoir, which was developed in collaboration with a group of cryogenic experts from Commissariat a L'Energie Atomique (CEA) in France. This concept meets all requirements and a conceptual design review was held in November 2002. However, meeting the completion date goal would be very difficult with this approach. Subsequent interaction with colleagues at… more

LEACHING OF SLAG FROM STEEL RECYCLING: RADIONUCLIDES AND STABLE ELEMENTS. DATA REPORT, JAN.15, 1997, REVISED SEPT.9, 1997

Description: Of primary importance to this study are releases of radionuclides from slags. However, releases of other constituents also provide valuable information on releases of elements that may be toxic (e.g. Cr) or that may be used as analogs for radionuclides (e.g. K for Cs). In addition, leaching of bulk constituents from the slag gives information on weathering rates of the bulk material that can be used to estimate releases of non-leachable elements. Consequently, we have examined leaching of: radi… more

Edge Detection to Isolate Motion in Adaptive Optics Systems

Description: Adaptive optics uses signal processing techniques and deformable mirrors to minimize image degradation caused by phase aberrations. In the case of telescope imaging, the atmosphere causes phase aberrations. In the case of satellite imaging, errors due to the ultra-light-weight characteristics of the primary mirror cause phase aberrations. Scene-based Shack-Hartmann Wave Front Sensing takes the correlation between successive wavelets to determine these phase aberrations. A large problem with the… more

40 Years of Discovery

Description: History is most interesting when seen through the eyes of those who lived it. In this 40th anniversary retrospective of bioscience research at Lawrence Livermore National Laboratory, we've asked 19 scientists to share their personal recollections about a major accomplishment in the program's history. We have not tried to create a comprehensive or seamless story. Rather, we've attempted to capture the perspectives of key individuals, each of whom worked on a research program that met significant… more
