### Abstract

GroundBIRD is a ground-based experiment designed to detect large angular scale odd-parity patterns in the cosmic microwave background (CMB) polarization ( {Mathematical expression}-modes). We employ a high-speed rotation scan (20 rpm) instead of the usual left-right azimuthal scan; it allows a significant expansion of the scan range to {Mathematical expression} without any effect from the detector {Mathematical expression} noise. We use microwave kinetic inductance detectors (MKIDs) arrays with a small telescope; our target multipole ( {Mathematical expression}) range is {Mathematical expression}. We plan to start the test observation in Japan in 2014; these will then be moved to the Atacama highland in Chile for scientific observations.
