Radio echo sounding is a uniquely powerful geophysical technique for studying the interior of ice sheets, glaciers, and icy planetary bodies. It can provide broad coverage and deep penetration as well as interpretable ice thickness, basal topography, and englacial radio stratigraphy. However, despite the long tradition of glaciological interpretation of radar images, quantitative analyses of radar sounding data are rare and face several technical challenges.

Abstract:

The WFI instrument of ESA’s next X-ray observatory ATHENA will provide excellent spectroscopic performance

in an unprecedented large field of view.  The focal plane consists of DEPFET active pixel sensors to typically produce

energy resolution below 170 eV FWHM @ 7 keV on a 512x512 pixels sensor with fast readout. The DEPFET concept

The LZ Experiment and Purification of the Xenon Target Using Gas Charcoal Chromatography

LZ will be a 10 ton dual-phase xenon Time Projection Chamber (TPC) searching for WIMP dark matter via direct scattering from xenon nuclei.  In order to achieve the desired sensitivity, corresponding to a few events per year, we require an extremely radiopure environment.  Most of our backgrounds originate outside of the bulk xenon and are mitigated by xenon’s self-shielding properties combined with precision e
