The objective of the project is the commercialization of the heterodyne detector for terahertz frequencies which was developed, manufactured and tested in the framework of the previous project. Within previous research, the authors of the project manufactured and tested a heterodyne detector for terahertz frequencies based on the hot electron phenomenon in thin superconducting NbN films. The detector manifested record performance. Under CRDF project PR2-2365-MO-02, a terahertz mixer was successfully applied for solution of several problems of radioastronomy. In particular, spectral line J9->8 of CO in a molecular cloud of the Orion was studied. Commercializing heterodyne detectors will call for other tasks to be solved. Firstly, it’s necessary to lower the cost price of superconducting mixers. The fabrication of thin superconducting films requires not only state-of-the-art equipment, but also developed technological methods and knowledge of the structure of the films, as well as certain skill on the part of operators. One of the mainstreams of the project is obtaining additional information about manufacturing superconducting nanometer-sized films with updated technological equipment of the project participants. Secondly, commercializing will involve research on, development and expansion of the terahertz superconducting detectors market. With the initial aim of terahertz radioastronomy, the authors will investigate the possibility of applying the detectors in medicine, for precision non-damage diagnosis of tissue, detection of explosives and biological objects. The main tasks of the project are as follows: • Complex study of ultrathin (2.5 – 4 nm) superconducting NbN films and improvement of the technology of films sputtering. • Improvement of technological methods of detector manufacture with updated technological equipment of the project participants. • The manufacture and testing of terahertz mixers. • Applying terahertz detectors for some radioastronomical projects. • The investigation of the possibility of applying the detectors in medicine, for precision non-damage diagnosis of tissue, detection of explosive and biological objects. • Informing potential customers through participation in conferences, exhibitions and the preparing and publishing of scientific works. Main project participants are: «Insight Product Company» (USA) Moscow State Pedagogical University (MSPU) Smithsonian Astrophysical Observatory (SAO) also contributes to the project. The main project results will be following: •development and realization of superconducting nanotechnology allowing to fabricate mixers for THz frequency range with improved and reproducible performances; significant decrease in cost price of mixing elements; •fabrication of superconducting heterodyne detector based receivers adapted for THz radioastronomy purposes; •broadening of superconducting receiving elements market; development of new applications for mixers in medicine, high resolution non-destroying diagnostics of living tissue, detection of explosives and biological objects; •wide presentation in scientific journals, symposiums and exhibitions of research into the utilization of THz range receiving systems; determination of potential consumers of developed systems. Collaboration efficiency of project participants is based on the presence of mutually complementary resources necessary for project accomplishment and participants’ benefits are the intended project results.
