Description
Dual-phase time projection chambers (TPCs) filled with liquid xenon (LXe) are a
widely-used technique for the direct search for dark matter in the form of weakly
interacting massive particles (WIMPs). One of the upcoming experiments exploiting
this technique is XENONnT, which aims at Dark Matter detection through the
scattering of WIMPs off the xenon nuclei. XENONnT will be filled with 8 t of ultra-
pure liquid Xenon, out of which will be 5.9 t in the active TPC. XENONnT will be
located at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy, at an average
depth of 3600 m water equivalent. After an overview on the XENONnT project, this
talk will present the working principles of the XENONnT TPC as well as the lessons
learned from the operating XENON1T.
