Paper Abstract

SAX will contain six instruments of which two will be Wide Field X-ray Cameras. Their design is based on the coded mask principle, mask and detector size are equal. We argue that this 'simple' camera design has certain advantages compared with the 'optimum' cameras where complete coding is pursued. The Field Of View (FWHM) is 20 degrees square, the angular resolution 5 arcminutes and the energy band ranges from 1.5 to 32 keV. The detector is a Multi Wire Proportional Counter with an area of 25.6 x 25.6 cm2, the position resolution is better than 0.5 mm. The mask pattern is based on a pseudo random array that has in principle ideal imaging capabilities. We show that the imaging imperfections due to incomplete coding can mostly be corrected for with image reconstruction techniques.
