Ground-based cosmic microwave background polarization experiment
QUaD
,
[1]
an acronym for
QUEST at DASI
, was a ground-based
cosmic microwave background
(CMB)
polarization
experiment at the
South Pole
.
QUEST
(
Q and U Extragalactic Sub-mm Telescope
) was the original name attributed to the
bolometer
detector instrument, while
DASI
is a famous CMB
interferometry
experiment credited with the first detection of CMB polarization. QUaD used the existing DASI mechanical infrastructure but replaced the DASI interferometric array with a bolometer detector at the end of a
cassegrain
optical system. The mount has housed the
Keck Array
since 2011.
