摘要
The Liquid Argon Time Projection Chamber (TPC) technique is a promising technology for future neutrino detectors. At LHEP of the University of Bern (Switzerland), R&D projects towards large detectors are on-going. The main goal is to prove long drift paths of the order of 10 m. Therefore, a liquid Argon TPC with 5m of drift distance is being constructed. Many other aspects of the liquid Argon TPC technology are also under investigation, such as a new device to generate high voltage in liquid Argon (Greinacher circuit), a recirculation filtering system and the multi photon ionization of liquid Argon with a UV laser. Two detectors are being built: a medium size prototype for specific detector technology studies, and ARGONTUBE, a 5 m long device.
