Initial Performance of BICEP3: A Degree Angular Scale 95 GHz Band Polarimeter

BICEP3 is a \(550~mm\) aperture telescope with cold, on-axis, refractive optics designed to observe at the \(95~GHz\) band from the South Pole. It is the newest member of the BICEP/Keck family of inflationary probes specifically designed to measure the polarization of the cosmic microwave background...

Beschreibung
Zusammenfassung:	BICEP3 is a \(550~mm\) aperture telescope with cold, on-axis, refractive optics designed to observe at the \(95~GHz\) band from the South Pole. It is the newest member of the BICEP/Keck family of inflationary probes specifically designed to measure the polarization of the cosmic microwave background (CMB) at degree-angular scales. BICEP3 is designed to house 1280 dual-polarization pixels, which, when fully-populated, totals to \(\sim\)9\(\times\) the number of pixels in a single Keck \(95~GHz\) receiver, thus further advancing the BICEP/Keck program's \(95~GHz\) mapping speed. BICEP3 was deployed during the austral summer of 2014-2015 with 9 detector tiles, to be increased to its full capacity of 20 in the second season. After instrument characterization measurements were taken, CMB observation commenced in April 2015. Together with multi-frequency observation data from Planck, BICEP2, and the Keck Array, BICEP3 is projected to set upper limits on the tensor-to-scalar ratio to \(r\) \(\lesssim 0.03\) at \(95\%\) C.L..
