Oxygen is the third most abundant element in our galaxy. The oxygen bearing molecules that have been detected do not account for the expected oxygen abundance in Molecular Clouds. Molecular oxygen (O2) could be a major reservoir for the missing oxygen. We at UCSB in conjunction with JPL and AT&T have designed, built, and tested a balloon borne radio telescope with the capability to observe O2 (118750 MHz) and CO (115271 MHz). Using an SIS mixer from NRAO and a digital auto‐correlator from JPL, the SIS Spectrometer (SISS) has achieved double sideband receiver temperature of 50K and a spectral resolution of 1 km/s. Using the 1 meter primary mirror on the UCSB balloon borne gondola, the SISS has a 10’ FWHM beam. |
