THz drive signal amplifier: realization

The WP3 is devoted to the realization of the THz source consisting of a micro vacuum amplifier to be driven by a suitable laser source (Photomixing or QCL). This novel approach to the THz generation requires different Task to define the Characteristic of the cathode ,how to couple the laser to the amplifying structure , the slow wave structure that best fit the performance requirements . Further the assembly and the testing phase are relevant section of WP3.
