| Primary Goal : The MAT experiment was a
ground based CMB telescope designed to map anisotropy on 0.2 - 1 degree
scales and to measure the angular power spectrum covering the range 50
< l < 400.
Receiver:
-
Two 40 GHz HEMT detectors at resolution of 0.9 degrees (one
in each polarization)
-
Four 30 GHz HEMT detectors at resolution of 0.6 degrees (two in each polarization)
-
Two 144 GHz SIS detectors at a resolution of 0.2 degrees (one in each polarization)
Optics: Five cooled corrugated feeds under-illuminate
a fixed off-axis parabolic mirror of 0.85m diameter. The mirror in turn
under-illuminates a large chopping flat (chopper). The chopper is closest
to the sky so that the illumination on the parabola is stationary.
Site: Cerro
Toco mountain located in the Northern Atacama Desert in Chile at 17,000
ft (5200 m).
Sky Coverage: approximately 600 square
