... Polish scientists at the Space Research Centre, Polish Academy of Sciences, in Wroclaw, south-west Poland, have constructed an instrument called SphinX (short for Solar PHotometer In X-rays), which is an X-ray spectrophotometer, that will obtain spectra in the energy range 0.5--15 keV in 256 energy channels with frequency of up to 100 times a second. ... SphinX is part of a package of instruments known as TESIS (PI Prof. Sergei Kuzin, Lebedev Institute, Moscow). ... Space Research Centre, . ...
