“…After a few hours the system stabilized at the nominal evaporation rate, fullfilling the requirement to cover the nominal duration of the flight (14 days). The 3 He refrigerator temperature during the flight has been 296 mK with temperature drifts smaller than 0.5 mK/h, providing an excellent environment for the operation of 4 arrays of Kinetic Inductance Detectors [19,20].…”

“…The intense development of kinetic inductance detectors by different research teams started in the 2000s (see, e. g., [115][116][117]), and this idea has brilliantly been developed to date [118,119] in world practice. A four-band sub-terahertz receiver built on detectors with kinetic inductances was successfully tested onboard the Olympo balloon observatory a short time ago [120] with the participation of representatives from the Nizhny Novgorod school of radiophysics. A bolometer at the edge of a superconducting transition [121], the principle of operation of which is based on the abrupt transition of a superconducting film to a resistive state when irradiated with an external signal, is another promising type of direct receivers.…”

We give a review of both our own original scientific results of the development of superconducting receivers for sub-terahertz astronomy and the main leading concepts of the global instrumentation. The analysis of current astronomical problems, the results of microwave astroclimate research, and the development of equipment for sub-terahertz radio astronomy studies justify the need and feasibility of a major infrastructure project in Russia to create a sub-terahertz telescope, as well as to enhance the implementation of the ongoing Millimetron and Suffa projects. The following results are discussed: i) superconducting coherent receivers and broadband subterahertz detectors for space, balloon, and ground-based radio telescopes have been developed and tested; ii) ultrasensitive receiving systems based on tunnel structures such as superconductorinsulator -superconductor (SIS) and superconductor -insulator -normal metal -insulatorsuperconductor (SINIS) have been created, fabricated, and examined; iii) a receiving array based on SINIS detectors and microwave readout system for such structures has been implemented; iv) methods for manufacturing high-quality tunnel structures Nb/AlO x /Nb and Nb/AlN/NbN based on niobium films with a current density of up to 30 kA/cm 2 have been developed. Receivers operated at 200 to 950 GHz and having a noise temperature only a factor of 2 to 5 higher than the quantum limit have been created and tested.

“…The most sensitive of these are superconducting detectors cooled down to sub-kelvin temperatures, which are the part of an integrated quasi-optical receiving system. The main competitors are transitionedge sensors (TESs) [1], kinetic inductance detectors (KIDs) [2,3], and superconductorinsulator-normal metal-insulator-superconductor (SINIS) detectors [4]. The main advantage of a TES is its high sensitivity, and the drawbacks are a narrow dynamic range, low speed, and a requirement of temperature stability.…”

Integrated quasi-optical cryogenic terahertz receivers contain arrays of detectors, quasi-optical filters, interferometers, and other metamaterials. Matrices of quasi-optical band-pass, low-pass, and high-pass filters, Fabry–Perot grid interferometers, and arrays of half-wave and electrically small antennas with superconductor-insulator-normal metal-insulator-superconductor (SINIS) sub-terahertz wavelength range detectors were fabricated and experimentally studied on the same computational, technological, and experimental platform. For the design of the filters, we used the periodic frequency-selective surfaces (FSS) approach, contrary to detector arrays that can be presented in a model of distributed absorbers. The structures were fabricated using direct electron beam lithography, thermal shadow evaporation, lift-off, alternatively magnetron sputtering, and chemical and plasma etching. The numerical simulation methods of such structures are sufficiently different: for the reactive matrices with low losses, the approximation of an infinite structure with periodic boundary conditions is applicable, and for the arrays of detectors with dissipative elements of absorbers, a complete analysis of the finite structure with hundreds of interacting ports is applicable. The difference is determined by the presence of dissipation in the detector arrays, the phase of the reflected or re-emitted signal turned out to be undefined and the Floquet periodic boundary conditions are correct only for a phased array antenna. The spectral characteristics of the created filters, interferometers, and antenna arrays were measured in the frequency range 50–600 GHz.
