Scientific paper

Attention is given to engineering design and operational aspects of the Multiple Mirror Telescope (MMT). A novel detector cooling system for the MMT's spectrographs permits echelle spectroscopy of extremely faint objects to be conducted, in order to obtain data bearing on such questions as the chemical abundances of the early universe, the velocity dispersions in globular clusters and dwarf spheroidal galaxies, and the rotation and magnetic fields of galactic stars. The MMT's IR photometer has identified many optically invisible radio sources, and is being used to devise an improved Cepheid period-luminosity relationship that is not affected by interstellar absorption.
