Abstract: (International Society for Optics and Photonics)

EBEX is a NASA-funded balloon-borne experiment designed to measure the polarization of the cosmic microwavebackground (CMB). Observations will be made using 1432 transition edge sensor (TES) bolometric detectorsread out with frequency multiplexed SQuIDs. EBEX will observe in three frequency bands centered at 150, 250,and 410 GHz, with 768, 384, and 280 detectors in each band, respectively. This broad frequency coverage isdesigned to provide valuable information about polarized foreground signals from dust. The polarized sky signalswill be modulated with an achromatic half wave plate (AHWP) rotating on a superconducting magnetic bearing(SMB) and analyzed with a fixed wire grid polarizer. EBEX will observe a patch covering ~1% of the sky with 8'resolution, allowing for observation of the angular power spectrum from l = 20 to 1000. This will allow EBEX tosearch for both the primordial B-mode signal predicted by inflation and the anticipated lensing B-mode signal.Calculations to predict EBEX constraints on r using expected noise levels show that, for a likelihood centeredaround zero and with negligible foregrounds, 99% of the area falls below r = 0.035. This value increases by afactor of 1.6 after a process of foreground subtraction. This estimate does not include systematic uncertainties.An engineering flight was launched in June, 2009, from Ft. Sumner, NM, and the long duration science flightin Antarctica is planned for 2011. These proceedings describe the EBEX instrument and the North Americanengineering flight.
