Applied physics: Terahertz power
Mark Sherwin
Top of page
Abstract
Although radiation at terahertz frequencies has many uses, most sources cannot generate terahertz beams with great power. Magnetic manipulation of energetic electrons inside a particle accelerator offers a solution.
This page emits a broad spectrum of electromagnetic radiation, including frequencies in the region of one terahertz (1 THz = 1012 Hz). You cannot see this terahertz emission because its frequency is about 300 times smaller than the limit of human vision.
