The instrument is equipped with a 1.5 meter aperture Gregorian-Dragone telescope, providing an 8' beam at three frequency bands centered on 150, 250 and 410 GHz. Polarimetry is achieved by rotating an achromatic half-wave plate on a superconducting magnetic bearing. In January 2013, EBEX completed 11 days of observations in a flight over Antarctica covering 6000 square degrees of the sky. Thls marks the first time that arrays with about= 1000 transition-edge sensor bolometers have made science observations on a balloon-borne platform. These proceedings describe the EBEX instrument, the science flight and the status of the data analysis.4 pagesen-USThis work was written as part of one of the author's official duties as an Employee of the United States Government and is therefore a work of the United States Government.
