(Cerro Chajnantor Atacama Telescope, Cornell Caltech Atacama Telescope)
(25 meter submillimeter telescope planned for Chile)
CCAT (for Cerro Chajnantor Atacama Telescope,
or the earlier name, Cornell Caltech Atacama Telescope)
is a proposed 25 meter telescope
with submillimeter cameras.
The planned site in Chile is at 5612 meters,
an extreme altitude for telescopes.
Originally it was hoped to be built between 2010 and 2020,
but since, a scaled-down 6-meter design (CCAT-p) is
slated for that time period, with the hope of
gaining experience and increasing interest
for the 25-meter version.
It is designed for a wide field of view (1 degree)
with wavelengths in the 200 to 2200um range.
- LWCam ("Long wavelength camera") - images six bands ranging from 750um to 3300um.
- SWCam ("Short wavelength camera") - images three bands ranging from 200um to 448um.
- X-spec (600-1600um spectrometer).
- CHAI ("CCAT Heterodyne Array Instrument").
