Abstract

Terahertz (THz) radiation, encompassing millimetre/submillimetre wavelengths (0.3THz-10THz), is one of the most desirable ranges of electromagnetic (EM) radiation. While sources capable of generating coherent THz radiation are continuously developing and subjects of exciting R&D programs, a significant frequency band from approximately 0.5THz to 5THz is still practically unbridged, with only occasional "steppingstones" appearing to support a limited number of research and industrial applications. This is specifically true for high power (>100W) compact and energy efficient (> 10%) sources of THz radiation. The project, stimulated by market research conducted and led by UKAEA, is to explore opportunities to construct high efficient (>10%) THz source potentially capable of generating >100W of coherent THz radiation (0.5 THz to 5 THz) in pulsed and CW regimes. The results of the market research based on more than 20 interviews will be also presented and discussed.
