XLZD represents the merging of multiple xenon-based detector concepts, including the XENON, LUX, and ZEPLIN detector technologies and the DARWIN detector concept for a very large dark matter detector. Recently, institutions that had been involved in the nEXO next-generation neutrinoless double-beta decay detector have joined the XLZD collaboration to support the planning of a future XLZD experiment. XLZD could hold anywhere between 60-80 tonnes of natural liquid xenon, a volume that also contains at least 5 tonnes of xenon-136 ... a sensitive neutrinoless double-beta decay isotope.
I am supporting the effort to develop ultra-radiopure materials, like copper, for the construction of a xenon time-projection chamber, the technology at the heart of the XLZD concept. In addition, my science interests are in dark matter detection and early warning detection for the next galactic supernova. XLZD will host the core xenon detector as well as outer water- and scintillator-based detector technologies that serve to protect the inner xenon volume. All of these together could provide a power supernova early warning system and yield insights into the different kinds of neutrinos in a supernova blast wave.
