KECK

The Keck Array

The Keck Array is a sensitive telescope for measuring the polarization of the cosmic microwave background (CMB) on degree angular scales.  Like its sister project, BICEP2, it is designed for excellent control of systematics.  The Keck Array is made up of several identical telescopes, with the multiple receivers giving increased mapping speed and greater sensitivity.  It deployed to its observing site at the geographic South Pole in late 2010, and is currently taking its first data with three receivers.  Two additional Keck telescopes will be added in the same mount in late 2011.

The Kuo group at KIPAC is one of the groups collaborating on the Keck Array, and four group members traveled to Antarctica for Keck deployment in the 2010/2011 season.  Our Keck Array collaborators are Harvard, Minnesota, Caltech, JPL, Case Western, NIST, British Columbia, and Toronto.
