The NeXT mission has been proposed to study high-energy non-thermal phenomenain the universe. The high-energy response of the super mirror will enable us toperform the first sensitive imaging observations up to 80 keV. The focal planedetector, which combines a fully depleted X-ray CCD and a pixellated CdTedetector, will provide spectra and images in the wide energy range from 0.5 keVto 80 keV. In the soft gamma-ray band up to ~1 MeV, a narrow field-of-viewCompton gamma-ray telescope utilizing several tens of layers of thin Si or CdTedetector will provide precise spectra with much higher sensitivity than presentinstruments. The continuum sensitivity will reach several times 10^(-8)photons/s/keV/cm^(2) in the hard X-ray region and a few times10^(-7)photons/s/keV/cm^(2) in the soft gamma-ray region.Comment: 12 pages, 13 figures, to be published in the SPIE proceedings 5488, typo corrected in sec.
