LArIAT: Liquid Argon In A Testbeam
arXiv: Instrumentation and Detectors, 2014
Liquid Argon Time Projection Chambers (LArTPCs) are ideal detectors for precision neutrino physics. These detectors, when located deep underground, can also be used for measurements of proton decay, and astrophysical neutrinos. The technology must be completely developed, up to very large mass scales, and fully mastered to construct and operate these detectors for this physics program. As part of an integrated plan of developing these detectors, accurate measurements in LArTPC of known particle species in the relevant energy ranges are now deemed as necessary. The LArIAT program aims to directly achieve these goals by deploying LArTPC detectors in a dedicated calibration test beam line at Fermilab. The set of measurements envisaged here are significant for both the short-baseline (SBN) and long-baseline (LBN) neutrino oscillation programs in the US, starting with MicroBooNE in the near term and with the adjoint near and far liquid argon detectors in the Booster beam line at Fermilab...

We present results on calibration runs performed with pions at the CERN SPS for different modules of the H 1 liquid argon calorimeter which consists of an electromagnetic section with lead absorbers and a hadronic section with steel absorbers. The data cover an energy range from 3 .7 to 205 GeV. Detailed comparisons of the data and simulation with GHEISHA 8 in the framework of GEANT 3 .14 are presented. The measured pion induced shower profiles are well described by the simulation. The total signal of pions on an energy scale determined from electron measurements is reproduced to better than 3% in various module configurations. After application of weighting functions, determined from Monte Carlo data and needed to achieve compensation, the reconstructed measured energies agree with simulation to about 3%. The energies of hadronic showers are reconstructed with a resolution of about 50%/~E ® 2%. This result is achieved by inclusion of signals from an iron streamer tube tail catcher behind the liquid argon stacks .

This is an important period for High Energy Physics: many recent results, including the Higgs discovery and its characterization, confirm the Standard Model. A crucial point for the future of Particle Physics is the study of neutrino masses and mixing representing the first established evidence of physics beyond the SM. Since 2011, the large value of the ?13 mixing angle opened the way to the investigation of CP violation in the neutrino sector. A next generation long baseline neutrino experiment (DUNE) has unprecedented potential to precisely measure the neutrino oscillation parameters, determine the neutrino mass hierarchy and has a very good chance to discover evidence for CP violation in the leptonic sector. The large underground neutrino detectors needed for this task will also address the search for proton decay and the observation of supernovae neutrinos. Giant Liquid Argon Time Projection Chambers (LAr TPCs) will be employed as neutrino targets and detectors. They provide bu...
Beam tests of the DØ uranium liquid argon end calorimeters
Nuclear Instruments & Methods in Physics Research Section A-accelerators Spectrometers Detectors and Associated Equipment, 1993
We describe the results of beam tests of three uranium-liquid argon calorimeter modules constructed for the Do detector at the Fermilab Tevatron collider. As part of the calibration procedure, these modules were exposed to beams of electrons, pions and muons between 10 and 150 GeV/c before their installation in the end calorimeter of the completed DO detector. We obtain an electromagnetic sampling resolution of 15 .7%/F and constant term of 0 .3% . The hadronic sampling resolution is 45%/F (degraded to 50%o/FE by the effects of upstream material) and the constant term is 4% . The calorimeter is linear to 0 .5%, and the electromagnetic to hadronic response ratio is between 1 .02 and 1 .09 over this range of momenta . For an electron efficiency of 95% we obtain a rejection factor against pions of -900-3000 for particles in the momentum range between 50 and 150 GeV/c . We also compare our results with the predictions of a detailed Monte Carlo simulation .

The ProtoDUNE-SP detector is a single-phase liquid argon time projection chamber with an active volume of 7.2× 6.0× 6.9 m^3. It is installed at the CERN Neutrino Platform in a specially-constructed beam that delivers charged pions, kaons, protons, muons and electrons with momenta in the range 0.3 GeV/c to 7 GeV/c. Beam line instrumentation provides accurate momentum measurements and particle identification. The ProtoDUNE-SP detector is a prototype for the first far detector module of the Deep Underground Neutrino Experiment, and it incorporates full-size components as designed for that module. This paper describes the beam line, the time projection chamber, the photon detectors, the cosmic-ray tagger, the signal processing and particle reconstruction. It presents the first results on ProtoDUNE-SP's performance, including noise and gain measurements, dE/dx calibration for muons, protons, pions and electrons, drift electron lifetime measurements, and photon detector noise, signal ...
The recent dramatic success of the ICARUS 300-ton liquid-argon time-projection-chamber prototype (1) indicates that it is timely to review the possibilities for large-scale application of this technology for accelerator-based neutrino physics, neutrino astrophysics, and proton decay (2). A full exploration of the MNS neutrino mixing matrix (and extensions if sterile neutrinos exist) should be possible if the large mixing angle MSW solution to the solar neu- trino problem presently favored by the data (3) is confirmed by futures measurements. A large detector for this purpose should be able to distinguish the charge of the lepton into which the neutrino converts, for which the detector should be immersed in a magnetic field. The most promising option for a large detector that can distinguish the charge of an electron is magnetized liquid argon (4, 5). However, all studies to date of liquid argon detectors suitable for neutrino physics (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17) have...
