Optimal operating parameters for next-generation xenon gas time projection chambers

K. Mistry, Y. Mei, D. R. Nygren

The next-generation of $0\nu \beta \beta$ searches are targeting half-life sensitivities towards 10${}^{27}$--10${}^{28}$ years. Gaseous xenon time projection chamber (GXeTPC) detectors may be abl…
