Cosmogenic Activation in Double Beta Decay Experiments

Double beta decay is a very rare nuclear process and, therefore, experiments intended to detect it must be operated deep underground and in ultra-low background conditions. Long-lived radioisotopes produced by the previous exposure of materials to cosmic rays on the Earth’s surface or even underground can become problematic for the required sensitivity. Here, the studies developed to quantify and reduce the activation yields in detectors and materials used in the set-up of these experiments will be reviewed, considering target materials like germanium, tellurium and xenon together with other ones commonly used like copper, lead, stainless steel or argon. Calculations following very different approaches and measurements from irradiation experiments using beams or directly cosmic rays will be considered for relevant radioisotopes. The effect of cosmogenic activation in present and future double beta decay projects based on different types of detectors will be analyzed too.

“…Five more event displays with the energy deposit of 511 keV are shown in Appendix B. Algorithms to distinguish 0νββ signals from gamma-ray backgrounds using topological information and machine learning method have been actively studied in xenon gas TPC experiments for 0νββ decay search [27] [28]. We are also studying an algorithm based on DenseNet [29] for future physics run [30]. (blue curve) and with the resolutions at K α , K β , and 511 keV peaks for A √ E + BE 2 (green curve).…”

A high-pressure xenon gas time projection chamber, with a unique cellular readout structure based on electroluminescence, has been developed for a large-scale neutrinoless double-beta decay search. In order to evaluate the detector performance and validate its design, a 180 L size prototype is being constructed and its commissioning with partial detector has been performed. The obtained energy resolution at 4.0 bar is 1.73 ± 0.07% (FWHM) at 511 keV. The energy resolution at the 136 Xe neutrinoless double-beta decay Q-value is estimated to be between 0.79
