MVA Sim image (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption This simulation shows magnetic vortex acceleration. The laser pulse comes from the left and passes through a target that is just thick and dense enough to absorb nearly all of its energy. On the other side, it generates a plasma channel with strong magnetic fields that can accelerate an intense proton beam.
