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. Nāmakanui was built by a team at ASIAA (Taiwan) and is on loan to the JCMT as a spare for the GLT. An overview of the new Nāmakanui instrument is available here. The 230 GHz receiver `Ū`ū is commissioned. The commissioning of the 345 GHz receiver `Āweoweo is ongoing.
