The CSO-JCMT Submillimeter Interferometer

Abstract
A linked submillimeter-wave interferometer using the CSO 10.4 m and the JCMT 15 m telescopes located on Mauna Kea at an elevation of 4200 m, has been built and tested successfully. The capabilities of the instrument and an outline of the type of observations that can be made with a single, fixed-baseline interferometer are given. In particular, an experiment to detect gas infalling onto low-mass protostellar sources is proposed. The design of the instrument is described briefly and the successful results of the first tests are summarized.
