CLASS is an array of 4 telescopes currently under construction in the Atacama Desert in Chile. CLASS will measure the polarization of the Cosmic Microwave Background (CMB) at four frequencies at the largest angular scales to search for the polarized imprint on the CMB from inflationary gravitational waves.
HAWC+ is a polarimeter for NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA). HAWC+ will provide array polarimetry from 50-300 microns. This instrument will measure magnetic fields and provide new insights into the role of magnetic fields in star formation as well into the physics of the dust itself.
