Developing New Techniques for Characterizing Optical Properties of Millimeter Wavelength Detectors

Adele Zawada with John Ruhl Developing New Techniques for Characterizing Optical Properties of Millimeter Wavelength Detectors Poster Characterization of the Cosmic Microwave Background (CMB) is a major focus of modern experimental research in cosmology and astrophysics. CMB photons carry important information that could expand our understanding about the origin and content of...

Polarization Properties of Half-wave Plates

Nicholas Clyde with John Ruhl Polarization Properties of Half-wave Plates Millimeter wave optical components are useful for current Cosmic Microwave Background Radiation (CMB) experiments in the field of astrophysics. Therefore, it is useful to characterize these components. The purpose of this study is to test specifically the polarization properties of Millimeter...

Measuring Scattering, Absorption, and Reflection Properties for Filters in the South Pole Telescope

Kristen McKee with John Ruhl Measuring Scattering, Absorption, and Reflection Properties for Filters in the South Pole Telescope A current problem with many ground-based telescope experiments, such as the South Pole Telescope, is that the optical loading on the detectors is undesirably high. In the South Pole Telescope, millimeter-wavelength photons from...

The Relativistic Hofstadter Problem

Evan Telford with Harsh Mathur The Relativistic Hofstadter Problem Hofstadter studied electrons in a strong magnetic field perturbed by a weak periodic potential on a square lattice. He found that the energy levels plotted as a function of the magnetic field formed a beautiful pattern with a recursive structure now Hofstadter...
