Positively charged 208Tl ions are transported through liquid xenon using electric fields in the range of 4–10 kV cm−1 and for drift distances up to 50 mm. From these measurements we deduce upper limits on the attenuation length for Tl ions in liquid xenon, resulting in a lifetime >5.5 s. In addition to these results, the field independent mobility of Tl bearing species in liquid xenon was measured to be 1.33±0.04×10−4cm2V−1s−1. This result, when coupled with those for other species by previous workers, suggests that positive ion mobility in liquid xenon is proportional to the hard-core radius. Applications to Ba ion collection in a double beta decay experiment are also discussed. [ABSTRACT FROM AUTHOR] |
