CORONAS-F Tracking
























IRIS

Flare Spectrometer

Institutes:
Ioffe Physical Technical Institute

Principal Investigators:
Dr. G.E. Kocharov


Scientific goals

IRIS is designed to study Solar flare activity in X-ray spectrum band.

Technical parameters

IRIS is capable of registering solar X-Ray energy spectra in 2-200 keV spectrum band with 2.5-0.01 sec temporal resolution and ~ 10-8erg cm-2s-1 (~ 0,1 nWt/m2) sensitivity.

Soft X-Ray emission in 2-15 keV band and hard X-Ray emission in 15-200 keV band are registered in the following channels

Soft X-Ray, keVHard X-Ray, keV
2.0-2.515-25
2.5-325-35
3.5-5.535-100
5.5-7100-200
7.5-11.5
11.5-15.5

Due to high sensitivity of the device in soft X-Ray band 1.74 - 2.07 Å (2-15 keV) even weak flares and X-Ray precursors are easily registered.
