Proton-ion collisions: Behind the scenes of a hybrid interaction

Protons to the right, ions to the left: the basic principle of proton-ion collisions at the LHC might seem straightforward. However, this is an almost unprecedented mode of collider operation, certainly unique at the energy ...

New accelerator to examine heavy-ion-beam approach

The Department of Energy's Heavy Ion Fusion Science Virtual National Laboratory (HIFS-VNL), whose member institutions include LLNL, Lawrence Berkeley National Laboratory (LBNL) and the Princeton Plasma Physics Laboratory, ...

Large Hadron Collider to run at 4 TeV per beam in 2012

(PhysOrg.com) -- CERN today announced that the Large Hadron Collider will run with a beam energy of 4 TeV this year, 0.5 TeV higher than in 2010 and 2011. This decision was taken by CERN management following the annual performance ...

'Dark plasmons' transmit energy

Microscopic channels of gold nanoparticles have the ability to transmit electromagnetic energy that starts as light and propagates via "dark plasmons," according to researchers at Rice University.

Catching tokamak fastballs: Controlling runaway electrons

a leading design concept for producing nuclear fusion energy—can, under certain rare fault conditions, produce beams of very energetic "runaway" electrons that have the potential to damage interior surfaces of the device. ...

Feeling the heat: 30 tons of fine control for fusion plasmas

A major upgrade to the DIII-D tokamak fusion reactor operated by General Atomics in San Diego will enable it to develop fusion plasmas that can burn indefinitely. Researchers installed a movable, 30-ton particle-beam heating ...
