Abstract

A design for a mirror array telescope for high energies (MARTHE) with almost 1000 cm2 effective area at 7 keV is described. Briefly, it consists of 36 modules. Each module contains Wolter I mirrors nested 6 deep. The system is small enough to be flown on an Aries rocket. With the current mirrors, the angular resolution at high contrast is 20" and the half power diameter for images is 1.5' at 1.5 keV and 3.5'-4' at 7 keV. Plans to improve upon this performance are discussed.
