Solar flares catalog
The SONG instrument consists of two blocks: detecting unit SONG-DM and electronics unit SONG-EM. Information recorded by the SONG- DM unit is processed and output to telemetry by means of the SONG-EM unit.
The SONG-DM device (solar neutrons, gamma-radiation) is intended for registration of neutral and charged particles within the following energy ranges:
– fluxes and energy release spectra of neutrons with energies of > 20 MeV;
– fluxes and spectra of γ with energies of 0.03–200 MeV;
– fluxes and spectra of electrons with energies of 11–108 MeV;
– fluxes of protons with energies of 200–300 MeV;
– total fluxes of electrons with energies of > 55 MeV and protons with energies of > 70 MeV.
The instrument is intended for registration of neutron flux up to ∼ 100 cm−2 s −1, γ — up to∼ 400 cm−2 s−1, electrons — up to ∼ 400400 cm−2 s−1, protons — up to ∼ 600400 cm−2 s−1. Overall size and mounting support: 350 × 350 × 560 mm3 ; (167 ± 0.2) mm + (167 ± 0.2) mm. Mass of the instrument does not exceed 50 kg. Power consumption of the instrument under standard conditions and power supply of 27+7 −3 V does not exceed 8 W. The instrument is located outside of the object. X-axis is directed to the Sun with accuracy of ±2 degrees. The SONG-DM instrument consists of radiation detectors, sampling and analyzing circuits, pulse devices, voltage converter for the detectors and electronics supplying inside one block. The SONG-DM instrument is operated combined with the SONG-EM manufactured by Slovakian colleagues.
Monitoring measurements of the X-ray intensity of the Sun with the SPR-N device are provided in the range of 15–100 keV. X-rays are detected by a CsI (Na) crystal with a diameter of 1.5 cm and a thickness of 0.3 cm with an effective area of ~ 2 cm2, above which is a cylindrical collimator providing the field of view of the detector within 5 degrees. To protect against charged particles, the crystal is placed in an anti-coincidence screen made of plastic scintillator (Fosvich). Measurements of count rates in the channels of the 15–40, 40–100 keV patrol detector are carried out continuously and independently of the measurement cycle of the polarization detectors and the operating modes of the device. The time resolution for the patrol detector of the device is determined by the exposure time, which was set by commands from the Earth and, as a rule, was equal to 4 seconds.
