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

RAYSECUR是一家加拿大公司，专门设计和生产用于安全应用的太赫兹成像系统。为了升级现有的系统和开发新的系统，公司需要频率更高、功率更大的太赫兹源。经典的真空电子器件(VED)如速调管和行波管(TWT)已经开发和使用了几十年，从kHz到GHz频段的射频代。为了将VED推进到太赫兹频段，VED电磁电路的尺寸必须缩小，横向电路的尺寸应该小于一毫米。直到最近，才有可能制造具有如此小特征的VED，但随着高精度微制造技术的发展，THzVED出现了机会。在Engage Grant的框架内，我们将：-回顾经典VED，并从缩小到THz波段的角度对其进行评估。-建立适用于太赫兹发电的VED的概念性数值模型。-对制造典型THzVED所需的微加工工具进行初步分析。该项目将帮助一家创新的加拿大公司开始雄心勃勃的研发，以开发一种新型的加拿大太赫兹源。这将巩固加拿大在太赫兹研究领域的世界领先地位。
