CORONAS-F Tracking


X-Ray Spectrometer and Photometer

Space Research Centre, Polish Academy of Sciences, Wroclaw, Poland
Astronomical Institute of the Check Republic
Institute of Terrestrial Magnetism, Ionosphere and Radio Wave Propagation, Troitsk, Russia.

Principal Investigators:
Z.Kordylevsky, J. Sylwester

Scientific goals

Study of the X-Ray emission from the solar active regions and flares. Measurements of temperature, element composition and radial velocities of the solar hot coronal plasma. Localization of the solar sources of X-Ray emission and study of their structure.

Technical parameters


The observations are carried out in four separate channels

Scan time of each spectrum: 120 seconds
Accumulation time of a single spectrum point: 0.4 - 0.6 - 0.8 seconds
(The accumulation time of a single spectrum point and the resulting number of measurement points in a spectrum for each scan is determined automatically using the maximum level of the previous spectrum).


Energy interval: 2-4 and 4-8 keV
Detector apertures: 0.3 and 0.01 cm2
Duration of single measurement: 2 seconds for low solar activity
  0.125 econds during solar flare

Structure and localization of an X-Ray source

Energy interval: 2-4 and 4-8 keV
