The Max-Planck-Institut fuer Radioastronomie and Steward Observatory are jointly planning the establishment of a submillimeter observatory on Mount Lemmon, Arizona. The telescope will have a diameter of 10 meters and enable diffraction-limited operation at a shortest wavelength of 350 microns. Thus the reflector surface accuracy will be about 15 microns and the pointing accuracy 1 arcsec. This paper describes the design of the telescope, which is being carried out in cooperation with design teams in German industry. The reflector support structure will be made of carbon fiber reinforced plastic (CFRP) to minimize thermal deformations. The reflector consists of composite panels, made of aluminum honeycomb core and CFRP skins. They will be replicated from molds, made of pyrex, which will be ground in the required paraboloidal shape by optical shop techniques.
