Munich physicists have succeeded in demonstrating plasma wakefield acceleration of subatomic particles in a miniaturized, laser-driven model. The new system provides a broader basis for the development of the next generation of particle accelerators. The plasma wakefield acceleration (PWFA) technique is regarded as a highly promising route to the next generation of particle accelerators. In…
Nanocrystalline LEDs: Red, Green, Yellow, Blue
The color of the light emitted by an LED can be tuned by altering the size of their semiconductor crystals. Ludwig-Maximilians-Universitaet (LMU) in Munich researchers have now found a clever and economical way of doing just that, which lends itself to industrial-scale production. Unlike our old friend the incandescent lightbulb, light-emitting diodes (or LEDs) produce…
