The Princeton IQU Experiment (PIQUE) and the Cosmic Anisotropy Polarization Mapper (CAPMAP) are experiments to measure the polarization of the Cosmic Microwave Background (CMB) on sub-degree scales in an area within 1 deg 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
