Dielectric laser accelerator creates focused electron beam . 10 Apr 2024 How it could work: electrons are injected into the dielectric laser accelerator (centre) from a source at the top left. The cavities are within the turquoise and gold bars, which are illuminated with laser light (shown in a salmon colour). In this example, the accelerated electrons are used to creat...
