Abstract :
A new class of Multi helix based THz vacuum electron devices is under consideration easily fabricated using unconventional applications of microfabrication technology and modern computer modeling. This configuration will extend the operating range of the helical slow wave circuit into the THz frequency band. The design of a ~140 GHz amplifier is described, which can be extended beyond 1.0 THz.
