Physicists may have managed to shrink the particle accelerator. They've managed to build the first prototype of a miniature particle accelerator that uses terahertz radiation instead of radio frequency structures.
In the electromagnetic spectrum, terahertz radiation lies between infrared radiation and microwaves. Particle accelerators usually rely on electromagnetic radiation from the radio frequency range. For example, DESY's particle accelerator, PETRA III, uses a frequency of around 500 megahertz. The wavelength of the terahertz radiation used in this experiment, though, is around one thousand times shorter. This means that everything else can be smaller, as well.
