    The spectrometer SPI (Spectrometer on INTEGRAL) is 100 times more sensitive than the previous high spectral-resolution space instruments. SPI performs spectral analysis of gamma-ray point sources and extended regions over an energy range between 20 keV and 8 MeV with an unprecedented energy resolution of 2.2 keV (FWHM) at 1.33 MeV.
