The Advanced Light Source: A new 1. 5 GeV synchrotron radiation facility at the Lawrence Berkeley Laboratory

Description: The Advanced Light Source (ALS), now under construction at the Lawrence Berkeley Laboratory, is being planned as a national user facility for the production of high-brightness and partially coherent x-ray and ultraviolet synchrotron radiation. The ALS is based on a low-emittance electron storage ring optimized for operation at 1.5 GeV with insertion devices in 11 long straight sections and up to 48 bend-magnet ports. High-brightness photon beams, from less than 10 eV to more than 1 keV, will be… more

TF-ripple loss of suprathermal alphas in ITER

Description: TF-ripple loss of alphas below the critical energy is calculated for a noncircular ITER plasma. For 14 toroidal field (TF) coils, the particle loss was found to be about 6%. About 0.6% of the initial alpha energy (3.5 MeV) is lost. 26 refs., 9 figs., 3 tabs.

Research drilling in young silicic volcanoes

Description: Magmatic activity, and particularly silicic magmatic activity, is the fundamental process by which continental crust forms and evolves. The transport of magma from deep crustal reservoirs to the surface is a neglected but important aspect of magmatic phenomena. It encompasses problems of eruptive behavior, hydrothermal circulation, and ore deposition, and must be understood in order to properly interpret deeper processes. Drilling provides a means for determining the relationship of shallow int… more

Small scale structure on cosmic strings

Description: I discuss our current understanding of cosmic string evolution, and focus on the question of small scale structure on strings, where most of the disagreements lie. I present a physical picture designed to put the role of the small scale structure into more intuitive terms. In this picture one can see how the small scale structure can feed back in a major way on the overall scaling solution. I also argue that it is easy for small scale numerical errors to feed back in just such a way. The intuit… more
