A broad band x-ray imaging spectrophotometer (BBXRIS) has been built for astrophysical studies. The BBXRIS is based on a large imaging gas scintillation proportional counter (LIGSPC), the combination of a gas scintillation proportional counter (GSPC) and a multiwire proportional counter (MWPC), which achieves 8% (FWHM) energy resolution and 1.5 mm (FWHM) spatial resolution at 5.9 keV. The LIGSP can be integrated with a grazing incidence mirror and a coded aperture mask to provide imaging over a broad range of x-ray energies. The authors present the results of tests involving the LIGSPC and a coded aperture mask, and discuss possible applications of the BBXRIS.
