We discuss and present the first results of MAXIPOL, a bolometric
balloon-borne experiment designed to measure the E-mode polarization of
the cosmic microwave background (CMB). MAXIPOL is the first bolometric CMB
experiment to observe the sky using rapid polarization modulation. It was
retrofitted from MAXIMA. The power spectra computed from the estimated
maps of Q and U Stokes parameters give weak evidence for an EE signal,
with a 96% probability that its amplitude is positive. The EB and BB
results are consistent with zero. These results are consistent with the
expected concordance LCDM model. All of the results are for one bin in
the range 150 <l < 694. Tests revealed no residual systematic errors in
the time or map domain.
We also briefly review the current status of AMiBA. The construction for
its first phase is completed, and it is now operating at Mauna Loa, Big
Island, Hawaii.
