A cryogenic rotation stage with a large clear aperture for the half-wave plates in the Spider instrument
Sean Bryan, Peter Ade, Mandana Amiri +47
We describe the cryogenic half-wave plate rotation mechanisms built for and used in Spider, a polarization-sensitive balloon-borne telescope array that observed the Cosmic Microwav…

Balloon-Borne Submillimeter Polarimetry of the Vela C Molecular Cloud: Systematic Dependence of Polarization Fraction on Column Density and Local Polarization-Angle Dispersion
Laura M. Fissel, Peter A. R. Ade, Francesco E. Angilè +27
We present results for Vela C obtained during the 2012 flight of the Balloon-borne Large Aperture Submillimeter Telescope for Polarimetry (BLASTPol). We mapped polarized intensity…

Empirical modelling of the BLASTPol achromatic half-wave plate for precision submillimetre polarimetry
Lorenzo Moncelsi, Peter Ade, Francesco Elio Angile +18
A cryogenic achromatic half-wave plate (HWP) for submillimetre astronomical polarimetry has been designed, manufactured, tested, and deployed in the Balloon-borne Large-Aperture Su…
