Zhang arXiv: 1903.12372 · 2019-07-17 ## TL;DR This paper presents detailed measurements of the beta-decay response in liquid xenon using the LUX detector, covering various electric fields and energies, to improve calibration accuracy for dark matter searches. ## Contribution It provides new high-statistics calibration data for liquid xenon beta-decay response across multiple electric fields and energies, enhancing detector calibration methods. ## Key findings - Mean light-to-charge ratio characterized for 13 electric fields. - Response data spans energies from 1.5 to 145 keV. - Results improve understanding of liquid xenon response for dark matter detection. ## Abstract We report results from an extensive set of measurements of the \b{eta}-decay response in liquid xenon.These measurements are derived from high-statistics calibration data from injected sources of both $^{3}$H and $^{14}$C in the LUX detector. The mean light-to-charge ratio is reported for 13 electric field values ranging from 43 to 491 V/cm, and for energies ranging from 1.5 to 145 keV. ## Full text _Full body text omitted from this summary view._ Fetch the complete paper as Markdown: https://tomesphere.com/paper/1903.12372/full.md ## Figures 13 figures with captions in the complete paper: https://tomesphere.com/paper/1903.12372/full.md ## References 32 references — full list in the complete paper: https://tomesphere.com/paper/1903.12372/full.md --- Source: https://tomesphere.com/paper/1903.12372
