Caltech Submillimeter Observatory

The Caltech Submillimeter Observatory (CSO) is a 10.4 meter submillimeter telescope at Mauna Kea Observatories, Mauna Kea, Hawaii. The telescope was built in 1985, operating until 2015 when operation was according to a deal to allow the Thirty Meter Telescope to be built at MKO. The CSO is slated for dismantling, and there are plans to reassemble it at the Llano de Chajnantor Observatory, the moved/rebuilt telescope to be rename the Leighton Chajnantor Telescope (LCT). CSO instruments:

• MUSIC - Multiwavelength Submillimeter Inductance Camera
• SHARC II - Submillimeter High Resolution Camera
• SHARP - SHARC II polarimeter.
• MAKO - 350μm camera.
• Z-Spec - broadband grating spectrometer.
• ZEUS-2 - long slit echelle grating spectrometer.
