Heterodyne Receivers

Currently JCMT supports a 16 receptor 350 GHz array receiver (HARP). The ACSIS spectrometer is used with all the heterodyne instruments. The receivers are further described here: HARP.

A new three-receiver heterodyne instrument, Nāmakanui, is currently being comissioned. An overview of the new Nāmakanui instrument is available here. Nāmakanui was built by a team at ASIAA (Taiwan) and is on loan the to the JCMT as a spare for the GLT.
