The ArDM (Argon Dark Matter, CERN RE18, LSC Exp-08-2010-ArDM) project is a direct Dark Matter search experiment, based on a ton scale liquid argon Time Projection Chamber. A leading candidate for the Dark Matter in the universe is the so-called WIMP (Weakly Interacting Massive Particle).

Recent years have seen a significant progress in PET (Positron Emission Tomography) instrumentation, boosted by the migration of technologies originally developed for high energy physics experiments into prototype PET devices.

CMS, the Compact Muon Solenoid experiment in operation at the LHC, is a 12000 tons detector based on a large, high field superconducting magnet.
In the past decade, a surprisingly large amount of astrophysical objects have been identified to radiate very-high energy gamma-rays.To significantly enhance the sensitivity, two dedicated observatories are planned in the Northern and Southern hemisphere, respectively. These observatories shall consist of more than 100 Cherenkov telescopes of three different sizes to also enlarge the energy range.
Groups: Biland, Pauss
So far, the ultra-fast cameras used by Cherenkov telescopes to measure very high-energy gamma-rays are always based on photo-multiplier tubes. Recently, solid states photosensors with comparable performance became available, but theire usage under the very harsh conditions intrinsic to such telescopes was heavily disputed. Our institute designed and constructed therefore a novel camera based on these sensors and installed it in a refurbished 4m telescope at La Palma.
The Laboratory for Ion Beam Physics (LIP) operates three accelerator based systems and serves as a national and international center for Accelerator Mass Spectrometry (AMS) and ion beam based technologies in the materials sciences.

AMS-ISS is designed to measure precisely charged particle and antiparticle spectra in space. One of the main physics goals is to investigate whether antimatter exists in the Universe today in a measurable quantity. In addition, like in the case of MAGIC, interesting searches for the existence of cold dark matter CDM are attempted.

The measurement of very high-energy gamma-rays using very large ground-based Cherenkov telescopes is a recent addition to the variety of experiments at the interface between Particle Physics, Astrophysics and Cosmology.
Within the standard model of particle physics, the decay of muons into three electrons "μ → eee" is only allowed at an extremely low and unmeasurable rate, because it violates the lepton flavour number symmetry.
OPERA (Oscillation Project with Emulsion-tRacking Apparatus) is a long baseline neutrino oscillation experiment to search for the appearance of tau neutrinos in the muon neutrino beam from CERN to the Gran Sasso (CNGS) in Italy.
This project aims to improve the current accuracy in the measurement of the energy interval of positronium (Ps) from its ground state (1S) to the first excited state (2S) by a factor of 5. This will provide a very stringent test of the theory describing atomic systems called bound states quantum electrodynamics (QED).
The T2K (Tokai to Kamioka) experiment is a second generation, long baseline neutrino oscillation experiment with the main goal to discover the transformation of muon neutrinos into electron neutrinos. A high intensity muon neutrino beam, the first so called superbeam, produced at the J-PARC laboratory near Tokai in Japan, is sent over a distance of 295 km across Japan towards the existing Super-Kamiokande (SK) detector.
