Abstract
The Princeton IQU Experiment (PIQUE) and the Cosmic Anisotropy Polarization Mapper (CAPMAP) are experiments designed to measure the polarization of the cosmic microwave background (CMB) on sub-degree scales in an area within 1° of the North Celestial Pole using heterodyne correlation polarimeters and off-axis telescopes located in central New Jersey. PIQUE produced the tightest limit on the CMB polarization prior to its detection by DASI, while CAPMAP has recently detected polarization at l ∼ 1000. The experimental methods and instrumentation for these two projects are described in detail with emphasis on the particular challenges involved in measuring the tiny polarized component of the CMB.
