B-Machine Polarimeter: A Telescope to Measure the Polarization of the
  Cosmic Microwave Background
  The B-Machine Telescope is the culmination of several years of development,
construction, characterization and observation. The telescope is a departure
from standard polarization chopping of correlation receivers to a half wave
plate technique. Typical polarimeters use a correlation receiver to chop the
polarization signal to overcome the $1/f$ noise inherent in HEMT amplifiers.
B-Machine uses a room temperature half wave plate technology to chop between
polarization states and measure the polarization signature of the CMB. The
telescope has a demodulated $1/f$ knee of 5 mHz and an average sensitivity of
1.6 $\mathrm{mK}\sqrt{\mathrm{s}}$. This document examines the construction,
characterization, observation of astronomical sources, and data set analysis of
B-Machine. Preliminary power spectra and sky maps with large sky coverage for
the first year data set are included.
