The XENONnT Field Cage

The XENONnT Field Cage

The central component of a dual-phase liquid xenon time projection chamber (TPC) is its field cage. This is the structure that establishes the electric field in which electrons drift across the TPC and ensures that this field is homogenious. A new articles, authored by members of Freiburg's astroparticle physics group, describes the field cage of the XENONnT dark matter detector. The field cage was designed by and many of its components were produced in Freiburg.

Gamma spectrometry for archaeology

Gamma spectrometry for archaeology

Using our low-background gamma spectrometer GeMSE for an interdisciplinary project with geologists and archeologists, we could proof that the iron used to produce an arrowhead in the Bronze Age is of extraterrestrial origin: most likely it comes from an iron meteorite that impacted on Estonia.

First results from a Search for New Physics in Electronic Recoils from XENONnT

First results from a Search for New Physics in Electronic Recoils from XENONnT

XENONnT, the latest detector of the XENON Dark Matter program, shows an unprecedentedly low background which facilitates searches for new, very rare phenomena with high sensitivity. First results clarify an exciting excess observed in the predecessor XENON1T and set strong limits on new physics scenarios.

Die Suche nach neuer Physik mit Elektron-Rückstoßsignalen: Erste Ergebnisse des XENONnT Experiments

Die Suche nach neuer Physik mit Elektron-Rückstoßsignalen: Erste Ergebnisse des XENONnT Experiments

XENONnT, der neueste Detektor der internationalen XENON-Kollaboration, zeigt ein bisher unerreicht niedriges Niveau an Untergrundsignalen, das eine empfindliche Suche nach neuen, sehr seltenen Phänomenen ermöglicht. Erste Ergebnisse klären nun ein aufregendes Signal, das im Vorgängerexperiment XENON1T beobachtet wurde, und setzen starke Grenzen für verschiedene Szenarien neuer Physik.

About GeMSE's new Background ... and a banana

A new paper describes the current background level of the group's GeMSE low-background spectrometer, the (almost) fully remote operation of the facility and a novel way to simulate the detection efficiency of complex-shaped (e.g., banana-like) objects.
