Plasma acceleration

Description
|
Lasers to accelerate: Extremely short, but high-intensity laser pulses fire on wafer-thin foils. The light heats up the material to such an extent that countless electrons emerge from it while the atomic cores remain in place. As the electrons are negatively charged and the atomic cores are positive, a strong electric field is formed between them for a short time. This field can catapult a proton pulse over only a few micrometers to energies that would require substantially longer distances using conventional accelerator technology.
