Abstract

The Large Millimeter Telescope/Gran Telescopio Milimetrico (LMT/GTM) is a joint project of the Instituto Nacional de Astrofisica Optica y Electronica, Tonantzintla, Mexico and the University of Massachusetts, Amherst, USA. The telescope will have an aperture of 50 m diameter with a surface accuracy of 75 micrometer and a pointing accuracy of 1.0 arcsec. The telescope is under construction on Cerro La Negra, Orizaba, Puebla, Mexico. The telescope is exposed to the severe environment at 4600 m altitude, will operate in up to 10 m/sec wind speed during sunshine or cold night and must survive thunderstorms, snow, ice etc. We describe the design features of the telescope and its subsystems, as the isostatic support of the carbonfiber reflector panels, the reflector backup structure and the thermal control system, the servo system including main axis drives and active surface control, the alidade with the large receiver rooms and excellent access to the science instruments, and the foundation on the volcanic summit of Cerro La Negra. The active deformation compensation system is described in a separate paper at this conference.
