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. …Read more.

The Relativistic Hofstadter Problem

Date posted: May 1st, 2014

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 butterfly. …Read more.

Modeling Gamma Ray Background from LUX

Dylan Yurgionas with Dan Akerib and Tom Shutt
Modeling Gamma Ray Background from LUX
Characterization of background is important for finding WIMP recoil events. Based on their cross sections, WIMPs will only scatter once inside the two phase xenon detector, LUX.  …Read more.

Capacitive level sensors for use in liquid xenon detectors

Date posted: May 1st, 2013

Jake Bell with Dan Akerib and Tom Shutt
Capacitive level sensors for use in liquid xenon detectors
[paper]
The LUX dark matter experiment liquid xenon detector uses an electric field created by grids to increase the drift velocity of electrons into xenon gas causing them to produce additional scintillation photons. …Read more.
