There is an interesting paper in Physical Review Letters this week with the mouthful of a title: “Enhancement of electron energy to the multi-GeV regime by a dual-stage laser-wakefield accelerator ...

The laser plasma accelerator has accelerated about half a billion electrons to 2 gigaelectronvolts over a distance of about 1 inch. It's a downsizing of a factor of approximately 10,000, and marks a ...

Gamma-ray bursts (GRBs) are the most electromagnetically luminous cosmic explosions. They are powered by collimated streams of plasma (jets) ejected by a newborn stellar-mass black hole or neutron ...
