Laboratory for High Energy Physics



16.07.2015 From high altitudes to deep underground tunnels

Scientists from the AEC Bern and the University of Zurich have studied the the cosmogenic activation of xenon after placing a bottle filled with pure xenon gas at the Jungfraujoch research station (3470 m). Xenon is successfully used as a target and detector material in several experiments searching for rare events, such as dark matter interaction or neutrinoless double beta decay. The intrinsic radioactive background in these experiments needs to be as low as possible, and activity intrinsic to the xenon, which is usually cooled down to -100°C and used in liquid form, is especially worrisome.

The Laboratory for High Energy Physics (LHEP) is a division of the Physics Institute at the University of Bern, Switzerland.
We conduct research in the field of experimental particle physics. The six main subjects are:

The LHEP has also been involved in experiments on low energy QCD studies, strange-matter, quark-gluon plasma, etc.
