Project Description:
EBEX (E & B Experiment) was a balloon-borne polarimeter designed to measure the intensity and polarization of the cosmic microwave background (CMB) radiation. EBEX will search for signals from the birth of the Universe and from gravitational bending of CMB radiation as it traverses the Universe enroute to the telescope. Measurements of the polarization of the CMB could probe an inflationary epoch that took place shortly after the big bang and significantly improve constraints on the values of several cosmological parameters. EBEX also provided critical information about the level of polarized galactic dust that will be necessary for use during future CMB polarization experiments.

Field Season Overview:
EBEX will be launched on a stratospheric balloon from Williams Field as a part of the CSBF ballooning operations (Stepp A-145). The field party of seventeen will begin arriving at McMurdo in late October with the expectation that the instrument will be launched in December.
