RAYSECUR is a Canadian company specialized in the design and production of terahertz imaging systems forx000D
security applications. In order to upgrade RAYSECURs existing systems and develop new ones companyx000D
needs a terahertz source with higher frequency and higher power.x000D
Classical vacuum electronic devices (VED) such as klystrons and traveling wave tubes (TWT) have beenx000D
developed and used for many decades for RF generations from kHz to GHz band. In order to push VEDs intox000D
the THz band, the size of the VED EM circuit must be scaled down that the transverse circuit dimensionsx000D
should be less than a millimeter. Fabrication of the VEDs with such a small feature was not possible untilx000D
recently but with development of highly accurate microfabrication techniques, an opportunity for THz VEDsx000D
has emerged.x000D
In the frame of ENGAGE grant we will:x000D
-Review classical VEDs and evaluate them from the point of view of scaling down to the THz band. -Buildx000D
conceptual numerical models of VEDs suitable for the THz generation.x000D
-Perform preliminary analysis of microfabrication tools needed to fabricate typical THz VEDs.x000D
The project will help an innovative Canadian company to start an ambitious R&D in order to develop a novelx000D
Canadian THz sources. This will consolidate the position of Canada as a world leader in the terahertz research.
