MAXIPOL
Overview
MAXIPOL (my Ph.D. thesis project) was a bolometric balloon-borne experiment designed to measure the E-mode polarization of the cosmic microwave background radiation (CMB). MAXIPOL was the first bolometric CMB experiment to observe the sky using rapid polarization modulation. To build MAXIPOL, the CMB temperature anisotropy experiment MAXIMA was retrofitted with a rotating half-wave plate and a stationary analyzer. Observations were made with 12 polarimeters operating at 140 GHz with a FWHM beam size of 10′. MAXIPOL was launched twice (see videos below) and ultimately made a detection of the expected E-mode signal.
