Abstract

We present the instrument integration and on-sky commissioning results for Kuntur, the LLAMA 690GHz receiver, on loan to the James Clerk Maxwell Telescope (JCMT). The LLAMA 690GHz receiver is a state-of-the-art sideband-separating (2SB), dual polarization receiver, built by the Netherlands Research School for Astronomy (NOVA) laboratory at Groningen, for the Large Latin American Millimeter Array (LLAMA), Argentina. In collaboration with LLAMA, the Institute of Astronomy and Astrophysics, Academia Sinica, Taiwan (ASIAA) and the Greenland Telescope (GLT), the receiver cartridge and WCA have come on loan to JCMT for on-sky commissioning and future VLBI observing tests. The results reveal the potential for single dish observing science at 690GHz with JCMT on Maunakea and provides a pointer to future 690GHz science for both the GLT and LLAMA.
