Description

Neutrinoless double beta decay is a proposed nuclear transition involving the emission of two electrons with no neutrinos. In 136Xe, observing the 136Ba daughter directly is a positive detection of double beta decay. This is barium tagging, and it would significantly enhance the signal to background ratio in experiments using a liquid xenon time projection chamber. However, extracting a single ion inside of a large cryogenic environment requires rapid and accurate motion of an ion collection probe. For this reason, we have developed a fine motion control apparatus to reliably position a thin capillary probe which enables the extraction and transport of single ions. I will present my work on the design and construction of the displacement apparatus along with studies on its ion extraction efficiency.
