High-resolution Airborne Wideband Camera Plus (HAWC+)
Facility class Science Instrument
Principal Investigator: Charles D. Dowell
NASA Jet Propulsion Laboratory (JPL)
HAWC+ is a far-infrared camera and imaging polarimeter. It is designed to allow total and polarized flux imaging in five broad bands between wavelengths of 50 μm and 240 μm. Diffraction-limited imaging yields spatial resolutions of ~5 – 20 arcseconds with fields of view ~2 – 10 arcminutes, respectively. HAWC+ utilizes three 31x40 pixel arrays: two for the reflective component and one for the transmitted component of linear polarization. The detectors are cooled by an adiabatic demagnetization refrigerator to an operating temperature of about 0.1 – 0.2 K. Commissioning observations started in late 2016, the instrument acceptance review was completed in late 2017, and has been available for Cycle 7 observations beginning in 2018.
