Scientific achievements, Hardware and methodological developments

1994

World-class sensitivity was reached at the RATAN-600 radio telescope in three centimeter wavelengths (2.7, 3.9, and 7.6 cm): 3.2, 3.4 and 2.5 mK/s, respectively through the introduction of cryogenic low-noise amplifiers based on the high electron mobility transistors (HEMT) in the radio astronomy observations.

A new-generation 2D-spectrograph featuring a CCD, mounted inside the high-aperture Schmidt camera was developed and put into service at the BTA telescope. In the visible spectral range (3000-10000 A) the quantum efficiency of 6-8% was reached, which corresponds to the world standards for the instruments of this type.

The prototype of the fluctuation damping circuit, which reduces the vibrations of the telescope in terms of the decay time by 5-6 times was developed and mounted at the BTA. The ability to create high-precision control systems for the BTA and other alt-azimuth systems with an order of magnitude higher precision characteristics under the wind loads on the telescope was experimentally demonstrated.
