Submillimeter Wave Telescope

NSSDCA ID: 1998-071A-01

Mission Name: SWAS
Principal Investigator:Dr. Gary J. Melnick


The SWAS instrument is a submillimeter wave telescope that incorporates dual heterodyne radiometers and an acousto-optical spectrometer. SWAS will measure water, molecular oxygen, atomic carbon, and isotopic carbon monoxide spectral line emissions from galactic interstellar clouds in the wavelength range 540-616 micrometers. Such submillimeter wave radiation cannot be detected from the ground because of atmospheric attenuation. The SWAS measurements will provide new information about the physical conditions (density and temperature) and chemistry in star-forming molecular clouds.
