24.02.2015 XENON1T Cryostat closed for the first time

The majority of the matter in the Universe consists of the so-called dark matter. The particle(s) which makes up this mysterious matter must be very different from all particles we know as of today, and remains still unknown. A prime candidate is the weakly interacting massive particle (WIMP), which is prediced by several extensions of the standard model of particle physics. The XENON1T experiment, which is currently being installed in the Laboratori Nazionali del Gran Sasso (LNGS) in the Italian Abbruzzo mountains, will search for the dark matter particle with an unprecedented sensitivity. It consists of about 3 tons of cryogenic liquid xenon, which is hold by a double-wall cryostat. On February 24, the outer cryostat has been closed for the first time, allowing for the evacuation of the insulation vacuum.

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.
