Scientists shrink electron gun to matchbox size: Terahertz technology has the potential to enable new applications

The new device uses laser generated terahertz radiation instead of the usual radio-frequency fields to accelerate electrons from rest. As the wavelength of the terahertz radiation is much shorter than radio-frequency radiation, the device can shrink...
