Wide Band X-Ray Imager (WXI) And Soft Gamma-Ray Detector (SGD) for the NeXT Mission
- SLAC
The NeXT mission has been proposed to study high-energy non-thermal phenomena in the universe. The high-energy response of the super mirror will enable us to perform the first sensitive imaging observations up to 80 keV. The focal plane detector, which combines a fully depleted X-ray CCD and a pixellated CdTe detector, will provide spectra and images in the wide energy range from 0.5 keV to 80 keV. In the soft gamma-ray band upto {approx} 1 MeV, a narrow field-of-view Compton gamma-ray telescope utilizing several tens of layers of thin Si or CdTe detector will provide precise spectra with much higher sensitivity than present instruments. The continuum sensitivity will reach several x 10{sup -8} photons/s/keV/cm{sup 2} in the hard X-ray region and a few x 10{sup -7} photons/s/keV/cm{sup 2} in the soft {gamma}-ray region.
