The first controlled studies of extremely hot, dense matter have overthrown the widely accepted 50-year old model used to explain how ions influence each other's behavior in a dense plasma. The results should benefit a wide ...

The Advanced WAKEfield Experiment (AWAKE) is a large experiment carried out at CERN that investigates plasma wakefield acceleration. It is the first research effort in this field to use a relativistic proton bunch as a driver ...
Twenty-five feet below ground, SLAC National Accelerator Laboratory scientist Spencer Gessner opens a large metal picnic basket. This is not your typical picnic basket filled with cheese, bread and fruit—it contains screws, ...
