| Abstract: | XENON100 is a dual-phase (liquid-gas) time projection chamber (TPC) containing a total of 161 kg of LXe with a 62 kg WIMP target mass, built with radiopure materials to achieve an ultra-low electromagnetic background and operated at the Laboratori Nazionali del Gran Sasso in Italy. Data from the XENON100 experiment have resulted in the most stringent limits on the spin-independent elastic WIMP-nucleon cross sections for WIMP masses above 8 GeV/c^2. I will present the experiment and its latest dark matter search results. I will also discuss a dedicated test facility built and operated at Columbia University to measure with high precision the scintillation response of LXe to low energy electron and nuclear recoils of interest to dark matter direct detection experiments like XENON. |
| Speaker: | Kyungeun Lim - Columbia University
 Kyungeun did her master's research at Ewha university in Korea, on the XMASS experiment in Kamioka, Japan. She started her Ph.D study at Columbia in 2006 and joined XENON in the summer of 2007. Most of her time from late 2007 to early 2009 was spent at the Laboratori Nazionali at Gran Sasso in Italy, during the detector construction and commissioning phase of XENON100.
Since 2009, she mostly worked at Nevis Lab in New York, focusing on the XENON100 data analysis and measurements of signal response of liquid xenon to low energy particles. She plans to defend her PhD. dissertation in November 2012.
