Article: The T2K Side Muon Range Detector
[show abstract] [hide abstract]
ABSTRACT: The T2K experiment is a long baseline neutrino oscillation experiment aiming to observe the appearance of {\nu} e in a {\nu}{\mu} beam. The {\nu}{\mu} beam is produced at the Japan Proton Accelerator Research Complex (J-PARC), observed with the 295 km distant Super- Kamiokande Detector and monitored by a suite of near detectors at 280m from the proton target. The near detectors include a magnetized off-axis detector (ND280) which measures the un-oscillated neutrino flux and neutrino cross sections. The present paper describes the outermost component of ND280 which is a side muon range detector (SMRD) composed of scintillation counters with embedded wavelength shifting fibers and Multi-Pixel Photon Counter read-out. The components, performance and response of the SMRD are presented.Nuclear Inst. and Methods in Physics Research, A. 01/2013; 698:135-146. -

Article: Underground operation of the ICARUS T600 LAr-TPC: first results
[show abstract] [hide abstract]
ABSTRACT: Open questions are still present in fundamental Physics and Cosmology, like the nature of Dark Matter, the matter-antimatter asymmetry and the validity of the particle interaction Standard Model. Addressing these questions requires a new generation of massive particle detectors exploring the subatomic and astrophysical worlds. ICARUS T600 is the first large mass (760 ton) example of a novel detector generation able to combine the imaging capabilities of the old famous "bubble chamber" with an excellent energy measurement in huge electronic detectors. ICARUS T600 now operates at the Gran Sasso underground laboratory, studying cosmic rays, neutrino oscillation and proton decay. Physical potentialities of this novel telescope are presented through few examples of neutrino interactions reconstructed with unprecedented details. Detector design and early operation are also reported.06/2011; -
Article: The T2K Experiment
[show abstract] [hide abstract]
ABSTRACT: The T2K experiment is a long-baseline neutrino oscillation experiment. Its main goal is to measure the last unknown lepton sector mixing angle {\theta}_{13} by observing {\nu}_e appearance in a {\nu}_{\mu} beam. It also aims to make a precision measurement of the known oscillation parameters, {\Delta}m^{2}_{23} and sin^{2} 2{\theta}_{23}, via {\nu}_{\mu} disappearance studies. Other goals of the experiment include various neutrino cross section measurements and sterile neutrino searches. The experiment uses an intense proton beam generated by the J-PARC accelerator in Tokai, Japan, and is composed of a neutrino beamline, a near detector complex (ND280), and a far detector (Super-Kamiokande) located 295 km away from J-PARC. This paper provides a comprehensive review of the instrumentation aspect of the T2K experiment and a summary of the vital information for each subsystem.06/2011; -

Article: The LAGUNA design study- towards giant liquid based underground detectors for neutrino physics and astrophysics and proton decay searches
[show abstract] [hide abstract]
ABSTRACT: The feasibility of a next generation neutrino observatory in Europe is being considered within the LAGUNA design study. To accommodate giant neutrino detectors and shield them from cosmic rays, a new very large underground infrastructure is required. Seven potential candidate sites in different parts of Europe and at several distances from CERN are being studied: Boulby (UK), Canfranc (Spain), Fr\'ejus (France/Italy), Pyh\"asalmi (Finland), Polkowice-Sieroszowice (Poland), Slanic (Romania) and Umbria (Italy). The design study aims at the comprehensive and coordinated technical assessment of each site, at a coherent cost estimation, and at a prioritization of the sites within the summer 2010.

Article: International Scoping Study (ISS) for a future neutrino factory and Super-Beam facility. Detectors and flux instrumentation for future neutrino facilities
[show abstract] [hide abstract]
ABSTRACT: This report summarises the conclusions from the detector group of the International Scoping Study of a future Neutrino Factory and Super-Beam neutrino facility. The baseline detector options for each possible neutrino beam are defined as follows: A very massive (Megaton) water Cherenkov detector is the baseline option for a sub-GeV Beta Beam and Super Beam facility. There are a number of possibilities for either a Beta Beam or Super Beam (SB) medium energy facility between 1–5 GeV. These include a totally active scintillating detector (TASD), a liquid argon TPC or a water Cherenkov detector. A 100 kton magnetized iron neutrino detector (MIND) is the baseline to detect the wrong sign muon final states (golden channel) at a high energy (20–50 GeV) neutrino factory from muon decay. A 10 kton hybrid neutrino magnetic emulsion cloud chamber detector for wrong sign tau detection (silver channel) is a possible complement to MIND, if one needs to resolve degeneracies that appear in the δ-θ13 parameter space.Journal of Instrumentation 05/2009; 4(05):T05001. · 1.87 Impact Factor -
Article: Large underground, liquid based detectors for astro-particle physics in Europe: scientific case and prospects
[show abstract] [hide abstract]
ABSTRACT: This document reports on a series of experimental and theoretical studies conducted to assess the astro-particle physics potential of three future large scale particle detectors proposed in Europe as next generation underground observatories. The proposed apparatuses employ three different and, to some extent, complementary detection techniques: GLACIER (liquid argon TPC), LENA (liquid scintillator) and MEMPHYS (water Cherenkov), based on the use of large mass of liquids as active detection media. The results of these studies are presented along with a critical discussion of the performance attainable by the three proposed approaches coupled to existing or planned underground laboratories, in relation to open and outstanding physics issues such as the search for matter instability, the detection of astrophysical neutrinos and geo-neutrinos and to the possible use of these detectors in future high intensity neutrino beams.Journal of Cosmology and Astroparticle Physics 11/2007; 2007(11):011. · 5.72 Impact Factor -
Article: Measurement of through-going particle momentum by means of multiple scattering with the ICARUS T600 TPC
[show abstract] [hide abstract]
ABSTRACT: The ICARUS collaboration has demonstrated, following the operation of a 600ton (T600) detector at shallow depth, that the technique based on liquid argon time projection chambers 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 νμ 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 demonstrates 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 almost a factor two using an algorithm based on the Kalman filtering technique.European Physical Journal C 01/2006; 48(2):667-676. · 3.63 Impact Factor -
Article: Characterization of ETL 9357FLA photomultiplier tubes for cryogenic temperature applications
[show abstract] [hide abstract]
ABSTRACT: We carried out a careful evaluation of the performance of the large cathode area ETL 9357FLA photomultiplier tube operating at cryogenic temperature. The measurements were focused on evaluating the parameters which mainly characterize the operating performances of the device down to 77 K and the spread of the distinctive features over 54 samples assembled in the ICARUS apparatus. The results that we obtained demonstrate that the photomultiplier is suited for light detection in such unconventional operating conditions, certifying this device for the direct measurement of scintillation light coming from noble-gas liquids in detectors dedicated to neutrino physics and dark matter research.

Article: All real forms of Uq(sl(4;C)) and D = 4 conformal quantum algebras
[show abstract] [hide abstract]
ABSTRACT: The star operations and reality conditions for the complex quantum algebra Uq(sl(4;C)) providing real quantum algebras Uq(o(6-k,k)) k = 0, 1, 2, 3 and Uq(su(3,1)) are classified. Standard and non-standard star operations are considered. It appears that only four choices of real forms (one with mod q mod =1, three with q real) provide real Hopf algebra Uq(su(2,2)) approximately=Uq(o(4,2)) describing D = 4 conformal quantum algebras. The authors show that only the antipode-extended Cartan-Weyl basis of Uq(sl(4;C)) permits one to define real q-deformed D = 4 conformal algebra generators. In order to obtain the real D = 4 Weyl algebra as the Hopf subalgebra of Uq (su(2,2)) only the non-standard real forms can be employed.Journal of Physics A General Physics 12/1998; 26(16):4047. -

ABSTRACT: The kappa -deformation of D=4 Poincare algebra is extended to the N=1 D=4 Poincare superalgebra. By the contraction of real Hopf superalgebra Uq(OSp(1 mod 4)) (q real) we obtain real Hopf algebra Ukappa (P4;1)(P4;1) is written in the form which in the limit of vanishing fermionic generators (supercharges) reduces to the kappa -Poincare algebra Ukappa (P4)(P4 describes D=4Poincare algebra) proposed by Lukierski, Nowicki and Ruegg (1991).Journal of Physics A General Physics 12/1998; 26(21):L1099. -
Article: Operator formalism on general algebraic curves
[show abstract] [hide abstract]
ABSTRACT: The usual Laurent expansion of the analytic tensors on the complex plane is generalized to any closed and orientable Riemann surface represented as an affine algebraic curve. As an application, the operator formalism for the b − c systems is developed. The physical states are expressed by means of creation and annihilation operators as in the complex plane and the correlation functions are evaluated starting from simple normal ordering rules. The Hilbert space of the theory exhibits an interesting internal structure, being splitted into n (n is the number of branches of the curve) independent Hilbert spaces. In this way we are able to realize new kinds of conformal field theories at genus zero with symmetry group Virn ⊗ G, Vir being the Virasoro group and G denoting a discrete and nonabelian crystallographic group. Exploiting the operator formalism a large collection of explicit formulas of string theory is derived. Finally, we develop as an important byproduct new methods in order to handle differential equations related to monodromy, like the Riemann monodromy problem.Journal of Geometry and Physics. 10/1994; -
Article: A canonical form of an algebraic equation for genus 3 Reimann surfaces

ABSTRACT: We propose a canonical form of an algebraic equation describing each conformal equivalence class of genus 3 nonhyperelliptic Riemann surface. The equation yields a 3-sheet covering with nine ramification points. This result can have applications in string theory and in the theory of solvable models in statistical mechanics.Letters in Mathematical Physics 12/1990; 21(1):1-5. · 1.82 Impact Factor -
Article: Analysis of the liquid argon purity in the ICARUS T600 TPC
[show abstract] [hide abstract]
ABSTRACT: The results reported in this paper are based on the analysis of the data recorded with the first half-module of the ICARUS T600 liquid argon Time Projection Chamber (LAr TPC), during a technical run that took place on surface in Pavia (Italy). We include results from the linearity, uniformity and calibration of the electronics, measurements on the electron drift velocity in LAr at different electric fields, as well as the LAr purity achievement of the detector. Two complementary techniques were used to measure the drift electron lifetime inside the active volume: the first, from the data of a purity monitor, gives a measurement localized in space; the second, based on the study of the signals produced by long minimum ionizing tracks crossing the detector, provides a LAr volume averaged value. Both methods yield consistent results over the whole data taking period and are compatible with an uniform LAr purity over the whole volume. The maximal drift electron lifetime value was recorded before the run stop and was about . From an interpretation of the observed drift electron lifetime as a function of time, we conclude that the adopted technology would allow for drift distances exceeding .Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. -
