“…For example, the heterodyne instrument HIFI (Heterodyne Instrument for the Far Infrared) has quite recently been operated as part of the Herschel space observatory [11]. At present, several space missions including the project "Millimetron" of the Russian Space Agency are under development [12]. The "Millimetron" observatory is aimed at studying astronomic objects in the Universe in the far infrared, submillimeter, and millimeter ranges of the electromagnetic spectrum with superhigh sensitivity in the single-telescope regime and an extremely high angular resolution in the regime of the ground-based and space-borne interferometer.…”

“…Solving these problems requires the development and manufacture of spectral heterodyne, filter, and bolometer receivers designed to operate in atmospheric transparency windows in ground-based instruments, and for space and balloon instruments without these restrictions. In particular, it is desirable to have a satellite similar to those being prepared as a part of the Millimetron [17,36], JWST [87], and other missions for the problems of studying the early Universe. However, a low-Earth orbiting satellite (500 to 1000 km altitudes) with a relatively small telescope (1.5 m in diameter) having a spatial resolution of 4-5 min of arc per pixel of the matrix and a receiving matrix in a range of 0.5 to 1.2 THz can also be applied.…”

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 noise temperature of an SIS mixer in double sideband regime (DSB) is theoretically limited only by the quantum value hf/2k B (here h is the Planck constant, f is the frequency of the received radiation, and kB is the Boltzmann constant). That is why heterodyne SIS receivers are used on the majority of both ground-based and space radio telescopes [4][5][6][7][8][9][10][11]; they employed in all high-frequency bands of the largest radio astronomy interferometer -the Atacama Large Millimeter/submillimeter Array (ALMA) [4][5][6][7][8]. The noise temperature of the 211-275 GHz SIS receiver is 40-60 K (in single-sideband mode at IF bandwidth of 4-12 GHz) [4].…”

The main task of the RFBR_BRICS project "Superconducting terahertz receivers for space and ground radio astronomy" is the development of terahertz technologies and the creation of superconductor-insulator-superconductor (SIS) receivers with quantum sensitivity for novel radio telescopes, including ultra-long baseline radio interferometers. This research program brings together scientific groups from four BRICS countries (Brazil, Russia, China and South Africa), which have a high international reputation and successful experience in the development of ultrasensitive receivers. The report discusses the working plan and the first results of the project; in particular development of the SISreceivers for Russian space program "Millimetron"
