Milestone 10-GeV experiment shines light on laser-plasma interactions
 https://www.sciencedaily.com/releases/2024/12/241211124511.htm
Summary:
 With dual lasers, researchers have accelerated a high-quality beam of electrons to 10 billion electronvolts in just 30 centimeters.
 The experiment gives scientists a 'frame-by-frame' look at how a petawatt laser interacts with a long plasma channel,
 knowledge that's crucial for building future compact particle accelerators.
