The E and B experiment (EBEX) is a balloon-borne telescope designed to measure the polarization of the CMB. The instrument is equipped with a 1.5 meter Gregorian-Dragone telescope, providing an 8' beam, which coupled with our scan strategy enables observations on scales appropriate for investigation both of primordial gravitational waves, and also of gravitational lensing of polarization anisotropy due to density inhomogeneities. Approximately 1100 transition edge sensor (TES) bolometers measured the CMB in three frequency bands centered at 150 GHz, 250 GHz and 410 GHz. The broad range of frequencies enables EBEX to uniquely characterize polarized dust emission from foreground sources. Polarimetry is achieved by an achromatic half-wave plate rotating on a superconducting magnetic bearing coupled with a wire grid polarizer. EBEX completed an 11 day flight over Antarctica in January 2013. Flight data was recovered and analysis is in progress.
