1. Overview of the R&D program on liquid Argon TPC‘s under development at the University of Bern
Next steps in Neutrino Physics: precise measurement of the oscillation parameters, search for CP violation and mass hierarchy. In parallel, exploit astroparticle physics neutrinos (atmospheric, solar, supernova). Need large-mass and high imaging-capability underground detectors. LAr TPC's are well suited to achieve these goals.

2. ARGONTUBE: liquid Argon TPC (5m drift)
5 m drift distance
At University of Bern a broad R&D program about the liquid Argon TPC technology is going on to prove the feasibility of large mass detectors with long drift.
liquid Argon TPC chamber with 5 m drift length
500 kV in liquid Argon
Impurities at the level of < 0.1ppb (life time > 3000 ms)
To conclude: We aim to run ARGONTUBE this year.
