Laser Wakefield Particle Accelerator Realized
deglr6328 writes "Researchers at Lawrence Berkeley National Lab's "l'OASIS" group have, for the first time, discovered a way to create high quality monochromatic beams of relativistic electrons using a 10 terawatt laser pulse focused on a specially formed plasma channel. The work is considered a landmark in new accelerator physics due to the fact that they are theoretically capable of creating extraordinarily high field accelerating gradients in the 100's of GeV per meter range; much higher than what's possible with the current gradients created by microwave frequency accelerators. The discovery could therefore open the door to far more efficient and compact staged particle accelerators utilizing next generation petawatt power lasers to achieve TeV scale particle energies and at lower energies, allow things like proton beam cancer therapy to be made affordable and widely available." -
Open Source Tools in Data Centers
An anonymous reader writes "There is a nice presentation on the L.A.S. Linux site entitled "Managing Data Center Functions with Open Source Tools" which was presented at Comdex 2003. It covers everything from IPtables to OpenNMS. As well as covering some less known but nice tools like NeDi, which lets you easily manage Cisco routers and swiches from a web browser."
