Koronas-Foton ( Russian Коронас-Фотон , also CORONAS-FOTON, for Complex Orbital Observations Near-Earth of Activity of the Sun ) is the name of a Russian solar research satellite . It is the third satellite from the Russian Koronas program and part of the international Living With a Star program.

history

Koronas-Foton is a successor to the Koronas-F and Koronas-I satellites, which were launched on March 2, 1994 and July 31, 2001, respectively. It is operated by Roskosmos , the Moscow Engineering-Physics Institute and the Research Institute for Electromechanics . The aim of the satellite is to study energy accumulation and the transfer of energy to accelerated particles during solar flares , to study the mechanisms of particle acceleration, the propagation and interaction of particles in the solar atmosphere, and to study solar activity in relation to physical- chemical processes in the upper atmosphere of the earth.

The satellite was launched on January 30, 2009 from launch site 32 of the Plesetsk cosmodrome with a Zyklon-3 and reached its planned orbit on the same day. After the energy supply collapsed in mid-January 2010, the satellite was abandoned a short time later. According to the plan, it should actually provide measurement data for at least three years.

Technical specifications

As satellite bus that was the Meteor-M - weather satellites used. The mass of the satellite is 1900 kg, of which 540 kg scientific payload is on board. The payload consists of:

  • the high energy spectrometer NATALYA-2M (MEPhI) for gamma ray spectroscopy in the range of 0.3-2000 MeV and neutrons 20-300 MeV
  • the low-energy gamma ray telescope RT-2 ( TATA Institute of Fundamental Research, India ) in the range of 10 - 150 keV and 0.1 - 2 MeV, a temporal resolution of less than 1 ms and a total weight of 55 kg. The telescope consists of three detectors RT-2 / S, RT-2 / G, RT-2 / GA (a composite scintillation detector with thallium- doped sodium iodide and with sodium-doped cesium iodide as detector material and a semiconductor - cadmium zinc telluride detector) and one Electronics block RT-2 / E.
  • Spectrometer / polarimeter for hard gamma rays PENGUIN-M (Ioffe Physical-Technical Institute, St. Petersburg) in the range of 20 - 150 keV (polarimeter), 2 - 10 keV (measurement) and 0.015 - 5 MeV (spectrometer)
  • the X-ray and gamma - ray spectrometer KONUS-RF (Ioffe) for measuring solar flares and gamma-ray bursts in the range of 10 keV - 12 MeV with high temporal resolution
  • Gamma ray monitor BRM (MEPhI) with six channels in the range of 20 - 600 keV with a time resolution of 2 - 3 ms
  • Six- channel UV monitor PHOKA (MEPhI) in the range from 1 - 130 nm
  • Telescope, coronograph or imaging spectrometer TESIS (Lebedev Physical Institute) that displays images in narrow spectral bands, e.g. B. the emission lines of HeII, SiXI, FeXXI - FeXXIII, MgXII, ... in the range of 13.2 - 13.6, 29.5 - 31.5 and 841.8 - 842.3 nm
  • Measuring instrument for charged particles ELECTRON-M-PESCA (Scobeltsyn Institute of Nuclear Physics at Moscow State University) to study the flux and energy of protons (1 - 20 MeV), electrons (0.2 - 2 MeV) and nucleons (Z < 26, 2 - 50 MeV / nucleon)
  • Charged Particle Measurement Instrument STEP-F (Kharkov National University) for studying the flux and energy of protons (9.8-61.0 MeV), electrons (0.4-14.3 MeV) and alpha particles (37-246 MeV )
  • Magnetometer SM-8M in the range of –55… +55 µT .

An X-band communication system with an output power of eight watts is available for data transmission . The planned life expectancy of the satellite is given as three years.
