In a thick-liquid protected chamber design, such as HYLIFE-II, a molten-salt is used to attenuate neutrons and protect the chamber structures from radiation damage. The molten-salt absorbs some of the material and energy given off by the target explosion. In the case of a fast ignition inertial fusion system, advanced targets have been proposed that may be Self-sufficient in the tritium breeding (i.e., the amount of tritium bred in target exceeds the amount burned). These ''tritium-lean'' targets contain approximately 0.5% tritium and 99.5% deuterium, but require a large pr of 10-20 g/cm{sup 2}. Although most of the yield is provided by D-T reactions, the majority of fusion reactions are D-D, which produces a net surplus of tritium. This aspect allows for greater freedom when selecting a liquid for the protective blanket (lithium-bearing compounds are not required). This study assesses characteristics of many single, binary, and ternary molten-salts. Using the NIST Properties of Molten Salts Database, approximately 4300 molten-salts were included in the study [1]. As an initial screening, salts were evaluated for their safety and environmental (S&E) characteristics, which included an assessment of waste disposal rating, contact dose, and radioactive afterheat. Salts that passed the S&E criteria were then evaluated …

The Linac Coherent Light Source (LCLS) is a 1.5 to 15 {angstrom}-wavelength free-electron laser (FEL), currently proposed for the Stanford Linear Accelerator Center (SLAC). The photon output consists of high brightness, transversely coherent pulses with duration <300 fs, together with a broad spontaneous spectrum with total power comparable to the coherent output. The output fluence, and pulse duration, pose special challenges for optical component and diagnostic designs. We first discuss the specific requirements for the initial scientific experiments, and our proposed solutions. We then describe the supporting research and development program that includes: experimental and theoretical material damage studies; high resolution multilayer design, fabrication, and testing; replicated closed-form optics design and manufacturing; BeB manufacturing; and low-z Fresnel lens design, fabrication and testing. Finally some novel concepts for optical components are presented.

This report explores the authority of BLM personnel regarding unauthorized cattle by reviewing the statutory authorities of BLM over the federal rangelands under its administration, and the regulations and administrative materials implementing those authorities in the context of grazing, trespass, impoundment and sale of unauthorized livestock.

There were 5 laser experiments conducted to date in FY-01 under the ongoing project to study the response of single crystal fcc materials under shock compression. An additional 10 laser shots are planned for August, 2001. This work has focused on developing capability to record diffraction from multiple lattice planes during the passage of a shock through a thin foil of single crystal copper, while simultaneously performing separate shock sample recovery experiments to study the residual deformation structure in the recovered samples.

Solar Electricity - The Power of Choice (formerly NREL PV Working With Industry) is a quarterly newsletter devoted to the photovoltaics (PV) research and development activities performed by NREL staff in concert with their industry and university partners. This issue is devoted to demonstrating that PV R and D is a valuable investment for the United States. The editorialist for this issue is Larry Kazmerski, director of the National Center for Photovoltaics.

The 120 GeV primary proton beamline for the NuMI-MINOS [1] experiment at Fermilab will transport one of the most intense high-energy beams ever constructed. in parallel operation with the Collider program, 80% of the intensity capability of the Fermilab Main Injector can be sent to NuMI. Radiation safety pertaining to residual activity, damage of equipment and irradiation of groundwater is a primary concern. A particular challenge is that this beam will be transported to and targeted in a cavern excavated in rock in an aquifer region. A model of the beamline, including transport elements and excavated enclosures, has been built in the radiation simulation program MARS. This model has been used to determine limits for allowable beam loss, and to study effects of instabilities and of various failure types. Some results obtained with this model are presented.

It is not unusual to place multiple accelerators in a common enclosure to save on civil construction costs. This often complicates operations, especially if accelerators are affecting each other. At Fermilab, the influence of a rapidly cycling Main Injector (MI) synchrotron on an antiproton storage ring (Recycler), placed in a common tunnel, was initially found to be unacceptable for a reliable operation of the Recycler. Initial closed orbit excursions in the Recycler ring during the MI ramp were in excess of 5 mm (rms). This paper describes a shielding technique, used to reduce these orbit excursions by a factor of five.

The Wide-Angle Neutron Diffractometer (WAND) installed at the High-Flux Isotope Reactor (HFIR) has been upgraded for new experiments. The main feature of this upgrade is the replacement of its detector with a newly developed curved one-dimensional 3He position-sensitive counter composed of 624 individual anodes. From the results of test-measurements of the detector performance, it is found that the intrinsic angular resolution and the maximum neutron-counting rate per anode are 0.25 degrees and 2.0 x 10 counts/second, respectively.
