A promising new detection technique is outlined which combines techniques pioneered in high pressure xenon gas, such as topological discrimination, with the high Q-value afforded by the double beta decay isotope Se-82. The lack of free electrons in SeF6 mandates the use of an ion TPC. The microphysics of ion production and drift, which have many nuances, are explored. Background estimates are presented, suggesting that such a detector may achieve background indices of better than 1 count per ton per year in the region of interest at the 100 kg scale, and still better at the ton-scale.", optnote="WOS:000428146300005", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=3541), last updated on Tue, 10 Apr 2018 18:08:51 +0000", issn="1748-0221", doi="10.1088/1748-0221/13/03/P03015", opturl="http://arxiv.org/abs/1801.04513", opturl="https://doi.org/10.1088/1748-0221/13/03/P03015", archivePrefix="arXiv", eprint="1801.04513", language="English" }
