Performance and on-sky optical characterization of the SPTpol instrument
E. M. George, P. Ade, K. A. Aird +62
In January 2012, the 10m South Pole Telescope (SPT) was equipped with a polarization-sensitive camera, SPTpol, in order to measure the polarization anisotropy of the cosmic microwa…
SPTpol: an instrument for CMB polarization measurements with the South Pole Telescope
J. E. Austermann, K. A. Aird, J. A. Beall +58
SPTpol is a dual-frequency polarization-sensitive camera that was deployed on the 10-meter South Pole Telescope in January 2012. SPTpol will measure the polarization anisotropy of…
Feedhorn-coupled TES polarimeter camera modules at 150 GHz for CMB polarization measurements with SPTpol
J. W. Henning, P. Ade, K. A. Aird +58
The SPTpol camera is a dichroic polarimetric receiver at 90 and 150 GHz. Deployed in January 2012 on the South Pole Telescope (SPT), SPTpol is looking for faint polarization signal…
Design and characterization of 90 GHz feedhorn-coupled TES polarimeter pixels in the SPTpol camera
J. T. Sayre, P. Ade, K. A. Aird +58
The SPTpol camera is a two-color, polarization-sensitive bolometer receiver, and was installed on the 10 meter South Pole Telescope in January 2012. SPTpol is designed to study the…
Improved Performance of TES Bolometers using Digital Feedback
Tijmen de Haan, Graeme Smecher, Matt Dobbs
Voltage biased, frequency multiplexed TES bolometers have become a widespread tool in mm-wave astrophysics. However, parasitic impedance and dynamic range issues can limit stabilit…
South Pole Telescope Software Systems: Control, Monitoring, and Data Acquisition
K. Story, E. Leitch, P. Ade +64
We present the software system used to control and operate the South Pole Telescope. The South Pole Telescope is a 10-meter millimeter-wavelength telescope designed to measure anis…
