Measurement of the two-photon absorption cross-section of liquid argon with a time projection chamber I Badhrees, A Ereditato, I Kreslo et al. . The detector we have designed and tested allowed us also to measure the two-photon absorption cross-section (σex) of LAr with unprecedented accuracy and precision, appropriate for using the UV laser technique also for a quantitative calibration of the detector. IntroductionThe liquid Argon Time Projection Chamber (LAr TPC) detector technology allows for uniform and high resolution imaging of massive detector volumes. The operating principle of the LAr TPC is based on the undistorted transport of tracks of ionizing electrons in highly purified LAr by a uniform electric field over distances up to a few metres. Imaging is provided by wire planes or other read-out devices placed at the end of the drift path. The drifting electrons are collected by the outermost wire plane which gives position and calorimetric information. Additional planes with different orientation can be positioned in front of the collection plane to record the signal induced by the passage of the drifting electrons. This provides different projective views of the same event thus allowing space point reconstruction. The third coordinate is given by the measurements of the drift time given by the time interval between the passage of the ionizing particle in the active volume (t 0 ) and the arrival of the drifting electrons on the wire planes. The t 0 can come from the detection of the scintillation light of liquid Argon by means of photomultipliers, or from an external source. The particle momentum of an incoming particle is inferred by the measurement of its multiple scattering [2], while the detection of the local energy deposition provides particle identification. For more information, the reader is referred to [1] and references therein quoted.A very large LAr TPC with a mass ranging from 10 kton to 100 kton would produce an important physics output thanks to the excellent event reconstruction performance [3,4,5,6,7]. The purity of the liquid Argon is a key ingredient to achieve imaging over long drift distances (>5 m), needed for building such a large masses. In particular, a purity corresponding to less than 0.1 ppb of electronegative elements such as Oxygen, has to be achieved in order to allow

Measurement of through-going particle momentum by means of multiple scattering with the ICARUS T600 TPC

The ICARUS collaboration has demonstrated, following the operation of a 600 ton (T600) detector at shallow depth, that the technique based on liquid Argon TPCs is now mature. The study of rare events, not contemplated in the Standard Model, can greatly benefit from the use of this kind of detectors. In particular, a deeper understanding of atmospheric neutrino properties will be obtained thanks to the unprecedented quality of the data ICARUS provides. However if we concentrate on the T600 performance, most of the ν µ charged current sample will be partially contained, due to the reduced dimensions of the detector. In this article, we address the problem of how well we can determine the kinematics of events having partially contained tracks. The analysis of a large sample of atmospheric muons collected during the T600 test run demonstrate that, in case the recorded track is at least one meter long, the muon momentum can be reconstructed by an algorithm that measures the Multiple Coulomb Scattering along the particle's path. Moreover, we show that momentum resolution can be improved by a factor two using an algorithm based on the Kalman Filtering technique.

“…The largest liquid Argon TPC ever build so far is the ICARUS T600 detector, whose successful assembly culminated with its full test carried out at surface during the summer 2001 [15,16,17,18,19,20]. Installation of this detector at the LNGS is ongoing and commissioning for data taking is expected in 2006.…”

“…Charged particles give two track segments in each emulsion film. The number of grain hits in about 50 µm (15)(16)(17)(18)(19)(20) ensures redundancy in the measurement of particle trajectories. By pilingup a series of cells in a sandwich-like structure bricks can be built, which constitute the detector element for the assembly of massive planar structures (walls).…”

We review detector technologies which are currently considered for ultimate nucleon decay searches, new generation astrophysical neutrinos studies, and for future long-baseline neutrino experiments at new high-intensity neutrino beam facilities. We focus our discussion on Phase-II experiments with a timescale of 10 ≃ 20 years. We point out that there are very few detector technologies which are general purpose and versatile enough in order to potentially address non-accelerator based physics and a large variety of future neutrino beam types ranging from superbeams, betabeams and neutrino factories from subGeV to 10's GeV energies.
