POLARBEAR (POLARization of the Background Radiation)[1] is a cosmic microwave background polarization experiment located in the Atacama Desert of northern Chile in the Antofagasta Region. The POLARBEAR experiment is mounted on the Huan Tran Telescope (HTT) at the James Ax Observatory in the Chajnantor Science Reserve. The HTT is located near the Atacama Cosmology Telescope on the slopes of Cerro Toco at an altitude of nearly 5,200 m (17,100 ft).[2][3]

POLARBEAR was developed by an international collaboration which includes University of California, Berkeley, Lawrence Berkeley National Lab, University of Colorado at Boulder, University of California, San Diego, Imperial College, Astroparticle and Cosmology Laboratory of the University of Paris (2019), KEK (High Energy Accelerator Research Organization), McGill University, and Cardiff University.
