The SPI High-Energy Sky
Proceedings of The Extreme sky: Sampling the Universe above 10 keV — PoS(extremesky2009)
We present here a summary of 7 years of observation at high energy with the SPI onboard the Integral spacecraft. SPI is a spectrometer working in the 20 keV -8 MeV energy range providing an unprecedented energy resolution over a large period of time. We will review the status of this instrument and we will demonstrate its quality and stability through key parameters: the energy resolution, gain calibration and the spectral response. SPI contributes to unveil the high energy sky thanks to itsdoi:10.22323/1.096.0005 fatcat:etgt7gft4jbbxnz44jaxecxjyu
