Photonis Defense was one of the first to introduce metal-to-ceramic construction to the industry which is now considered the standard. They where also the first to apply fast warm-up technology to Miniature Traveling Wave Tubes in a production environment. Photonis manufactures helix-type TWTs with periodic permanent magnet (PPM) focusing providing excellent broadband performance. The majority of Photonis TWTs are conduction cooled.
