By David Ponce Todd Johnson has been making ShockFossils for a while now but we just came across his work and are impressed beyond words. They are acrylic pieces with fractal designs that were created using a particle accelerator. Todd takes blocks of acrylic and brings them to an industrial accelerator facility where he rents [...]
Todd Johnson's Shockfossils are "multimillion volt Lichtenberg figures in acrylic." He masks acrylic slabs with lead and then rents time on a commercial particle accelerator and the result are beautiful, fern-like fractals. Shockfossils on deviantART
In this month's Physics World, reviews and careers editor, Margaret Harris, visits the Fermi National Accelerator Laboratory (Fermilab) to explore what future projects are in the pipeline now that the Tevatron particle accelerator has closed for good.
Want to hang out with the people who run the CMS? No, not the content management system. The Compact Muon Solenoid. It's one of the two big detectors at the Large Hadron Collider (LHC), the largest and highest-energy particle accelerator in the world.
CERN physicist Dr. Albert De Roeck is hosting a Google+ Hangout tomorrow from inside the cavern where the experiment takes place, about 100 meters underneath Cessy, France. He'll explain the CMS...
Today the two main experiments at the Large Hadron Collider (LHC), the world’s most powerful particle accelerator, submitted the results of their latest analyses. The new papers boost the case for December’s announcement of a possible Higgs signal , but let’s not get too excited. [More]
Scientists working at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have created the shortest, purest X-ray laser pulses ever achieved, fulfilling a 45-year-old prediction and opening the door to a new range of scientific discovery. The researchers, reporting today in Nature, aimed SLAC's Linac Coherent Light Source (LCLS) at a capsule of neon gas, setting off an avalanche of X-ray emissions to create the world's first "atomic X-ray laser." This artist's...Read Full Story
Scientists will soon be exploring matter at temperatures and pressures so extreme it can only be produced for microseconds using powerful pulsed lasers. Matter in such states is present in the Earth's liquid iron core, 2500 kilometres beneath the surface, and also in elusive "warm dense matter" inside large planets like Jupiter. A new X-ray beamline ID24 at the European Synchrotron Radiation Facility (ESRF) in Grenoble, France, allows a new quality of exploration of the last white spot on our...Read Full Story
This month physicist Juan Collar and his associates are taking their attempt to unmask the secret identity of dark matter into a Canadian mine more than a mile underground.
The team is deploying a 4-kilogram bubble chamber at SNOLab, which is part of the Sudbury Neutrino Observatory in Ontario, Canada. A second 60-kilogram chamber will follow later this year. Scientists anticipate that dark matter particles will leave bubbles in their tracks when passing through the liquid in one of these...Read Full Story
Scientists from Finland and France have developed a new synchrotron X-ray technique that may revolutionize the chemical analysis of rare materials like meteoric rock samples or fossils. The results have been published on 29 May 2011 in Nature Materials as an advance online publication.
A diamond surrounded by air, and a glass of water. Both contain carbon and oxygen. If they are embedded inside another object, without access for a chemical probe, it is a difficult task to distinguish...Read Full Story
A lightning researcher at the University of Bath has discovered that during thunderstorms, giant natural particle accelerators can form 40 km above the surface of the Earth.
Dr Martin Füllekrug from the University’s Department of Electronic & Electrical Engineering presented his new work on Wednesday 14 April at the Royal Astronomical Society National Astronomy Meeting (RAS NAM 2010) in Glasgow.
Dr Füllekrug and colleagues have discovered that natural particle accelerators can be formed...Read Full Story
