Heterodyne Receivers

Currently JCMT support a single receptor 230 GHz receiver (RxA) and a 16 receptor 350 GHz array receiver (HARP). The ACSIS spectrometer is used with all the heterodyne instruments. The receivers are further described on the pages RxA and HARP.
The 660 GHz receiver RxW is not operational at the moment.
