KFRD was designed by Moscow Space Research Institute of Russian Academy
of Science (IKI RAN) and Design Bureau OKB "Aalam" (Bishkek,Kirgyzstan).
The detector of KFRD is a Multiware Proportional Counter
(MWPC). The experience which was got during development and exploitation
of ART-P X-Ray telescope on board GRANAT
satellite was used in development of KFRD.
KFRD is being developed to be main focal plane imaging instrument of SODART Mirror X-ray telescope on board of the international space observatory SPECTRUM-X-GAMMA.
The energy range of detector is 2-25 keV, energy resolution at 6 keV is 18%, position resolution is 0.5 mm.
The sensitive volume of the KFRD detector is pictured above.
The effective area and detector parameters are given below.
