Project Description
SPARO measures linear polarization of
l = 450 mm emission from magnetically
aligned dust grains
4 arcmin resolution: complementary to
U. of Chicago polarimeter for CSO (18
arcsec resolution)
Uses two He-3 cooled bolometer arrays
of 9 pixels each
Background-limited at South Pole:
science goals cannot be achieved at any
other site
Cryostat designed for S. Pole winter
