The IFAE neutrino group is involved in two aspects of the neutrino physics. On one side, the group is contributing to the neutrino oscillation experiment T2K in Japan. The contributions of the IFAE group to the T2K experiment focus on the near detector, specifically in the construction of the time projection chamber and the refurbishing of the old magnet that was donated by CERN to the European members in T2K.

The activities in the TPC project include the production and testing of the readout detectors, MicroMegas, done in collaboration with University of Geneva, INFN Bari, IFIC, Saclay in Paris and CERN. IFAE members also provide the test bench for the front-end electronic modules produced in Saclay and the development of the data acquisition code for the test beams carried out at TRIUMF (Canada) during the last quarter of 2008.

Other activities include the development of the TPC reconstruction software and the coordination the reconstruction group of the T2K near detector. One of us is also coordinating the physics analysis group for the neutrino charged current interactions. In this sense, one of the members of the group is performing an analysis of the charged current quasielastic interactions in SciBoone. This experiment has a neutrino spectrum similar to T2K and it is built by a subgroup of T2K members to anticipate the physic studies there.

The contribution to the magnet refurbishing complies two areas. The manifolds distributing the cooling water to the magnet coils have been designed and constructed at the IFAE. The IFAE is also in charge of the slow control of the magnet that was implemented based on industrial hardware. The slow control is in charge of monitoring the running conditions of the magnet: temperature, cooling water temperature, coils voltage drop, etc... It is also in charge of detecting anomalies and switching off the magnet current and generates alarms.

The other activities are related to the development of instrumentation for radiation detection. These activities include the development of a TPC readout based on electroluminiscence using Avalanche Photodiodes as light photosensors, and gas detectors based on MediPix readouts. The IFAE neutrino group has also joined the R&D at CERN to develop technology for a large liquid argon detector within the WA105 experiment. This is a large two phase Liquid Argon tank to prove the viability of several of the required technologies for the kiloton scale detectors. These developments are carried out within the RD51 collaboration at CERN. Recently the group has joined efforts with the Institut Catala d'investigation Quimic (ICIQ) in Tarragona to develop new X-Ray detectors based on the novel perovskite semiconductors.
