2-D electric fields and drifts near the magnetic separatrix in divertor tokamaks (open access)

2-D electric fields and drifts near the magnetic separatrix in divertor tokamaks

A 2-D calculation is presented for the transport of plasma in the edge region of a divertor tokamak solving continuity, momentum, and energy balance fluid equations. The model uses anomalous radial diffusion, including perpendicular ion momentum, and classical cross-field drifts transport. Parallel and perpendicular currents yield a self-consistent electrostatic potential on both sides of the magnetic separatrix. Outside the separatrix, the simulation extends to material divertor plates where the incident plasma is recycled as neutral gas and where the plate sheath and parallel currents dominate the potential structure. Inside the separatrix, various radial current terms - from viscosity, charge-exchange and poloidal damping, inertia, and {triangledown}B - contribute to the determining the potential. The model rigorously enforces cancellation of gyro-viscous and magnetization terms from the transport equations. The results emphasize the importance of E x B particle flow under the X-point which depends on the sign of the toroidal magnetic field. Radial electric field (E{sub y}) profiles at the outer midplane are small with weak shear when high L-mode diffusion coefficients are used and are large with strong shear when smaller H-mode diffusion coefficients are used. The magnitude and shear of the electric field (E{sub y}) is larger both when the …

1998 Complex Systems Summer School (open access)

1998 Complex Systems Summer School

For the past eleven years a group of institutes, centers, and universities throughout the country have sponsored a summer school in Santa Fe, New Mexico as part of an interdisciplinary effort to promote the understanding of complex systems. The goal of these summer schools is to provide graduate students, postdoctoral fellows and active research scientists with an introduction to the study of complex behavior in mathematical, physical, and living systems. The Center for Nonlinear Studies supported the eleventh in this series of highly successful schools in Santa Fe in June, 1998.

Agricultural Research, Education, and Extension Issues in the 105th Congress (open access)

Agricultural Research, Education, and Extension Issues in the 105th Congress

The public agricultural research, education, and extension system is comprised of a nationwide network of federal and state agricultural research laboratories and departments, land grant Colleges of Agriculture, colleges of forestry and veterinary medicine, and the nationwide Cooperative Extension System. Although the basic authority to conduct agricultural research and extension programs is permanent, Congress since 1977 has provided funding authority and policy guidance for USDA's in-house research programs, and for federal support for cooperative research, higher education, and extension programs in the states, through a title contained in omnibus farm legislation. This report discusses specific pieces of such legislation and details certain agricultural and food-related appropriations.

Los Alamos National Laboratory emergency management plan. Revision 1 (open access)

Los Alamos National Laboratory emergency management plan. Revision 1

The Laboratory has developed this Emergency Management Plan (EMP) to assist in emergency planning, preparedness, and response to anticipated and actual emergencies. The Plan establishes guidance for ensuring safe Laboratory operation, protection of the environment, and safeguarding Department of Energy (DOE) property. Detailed information and specific instructions required by emergency response personnel to implement the EMP are contained in the Emergency Management Plan Implementing Procedure (EMPIP) document, which consists of individual EMPIPs. The EMP and EMPIPs may be used to assist in resolving emergencies including but not limited to fires, high-energy accidents, hazardous material releases (radioactive and nonradioactive), security incidents, transportation accidents, electrical accidents, and natural disasters.

Alignment and micro-inspection system (open access)

Alignment and micro-inspection system

A video microscope system has been designed and installed in the C-tank, a 3-g, high-explosive firing chamber in HEAF (High Explosives Applications Facility in LLNL). This microscope system helps a great deal, not only for precision alignment of the laser beam on the minute target for the Fabry-Perot velocimeter, but also for in situ inspection of the target before and after the experiment. In addition, the video information can also be stored in the PC computer as database documentati
