The EXO-200 Liquid Xenon Time Projection Chamber

The Enriched Xenon Observatory (EXO) is an experimental program to search for neutrinoless double beta decay in 136Xe. The first EXO experiment, EXO-200, consists of a time projection chamber (TPC) filled with 200 kg of liquid xenon. In this way, the xenon is both the source and the ionized/scintillating medium needed for the TPC. The detector is installed 2250 feet underground at the WIPP facility in Carlsbad, NM, and is currently taking data. I will discuss the design and operation of the detector.
