1933 : Société d’histoire et du Musée du Florival

L’idée de créer un musée à Guebwiller remonte à l’année 1864, mais ne put déboucher sur une réalisation concrète. Dans les années 1920, Charles Wetterwald, passionné d’histoire locale, commença à rassembler divers objets pour constituer l’embryon d’un musée de la guerre, enrichis par d’autres témoins du patrimoine local. Charles Wetterwald (1872-1972), fondateur du musée et de la Société Au début de 1933, le Musée du Florival était installé dans un local de l’école de la ville haute de Guebw..

Estivales 2015 - Et vlan, la réforme territoriale : quid des bibliothèques ?

Les Estivales, manifestation annuelle de l\u27enssib, sont consacrées en 2015 à la réforme territoriale et à ses conséquences sur les bibliothèques. Tout l\u27enjeu est d\u27aborder cette réforme à un moment où la loi, certes votée, laisse place à de nombreuses questions. Il s\u27agit d\u27apporter de la matière à penser, notamment à partir de points de vue historique, géographique et administratif, sans oublier une certaine approche pragmatique qui puisse aussi nourrir les attentes de chacun sur le terrain

Estivales 2014 : Se passer des bibliothèques ?

Les Estivales, manifestation annuelle de l\u27enssib, seront consacrées en 2014 à la question suivante, cruciale et politique : "Se passer des bibliothèques ?" L\u27idée est à la fois d\u27interroger la place des bibliothèques dans les politiques publiques, de mettre en valeur leur utilité en termes d\u27impacts social, urbain, éducatif, économique... et d\u27observer notre capacité à valoriser cette utilité en direction des publics et des élus. Deux journées de tables rondes et de conférences permettront d\u27ouvrir le débat et de nourrir la réflexion sur ces questions

DUNE Offline Computing Conceptual Design Report

This document describes Offline Software and Computing for the Deep Underground Neutrino Experiment (DUNE) experiment, in particular, the conceptual design of the offline computing needed to accomplish its physics goals. Our emphasis in this document is the development of the computing infrastructure needed to acquire, catalog, reconstruct, simulate and analyze the data from the DUNE experiment and its prototypes. In this effort, we concentrate on developing the tools and systems thatfacilitate the development and deployment of advanced algorithms. Rather than prescribing particular algorithms, our goal is to provide resources that are flexible and accessible enough to support creative software solutions as HEP computing evolves and to provide computing that achieves the physics goals of the DUNE experiment

Highly-parallelized simulation of a pixelated LArTPC on a GPU

The rapid development of general-purpose computing on graphics processing units (GPGPU) is allowing the implementation of highly-parallelized Monte Carlo simulation chains for particle physics experiments. This technique is particularly suitable for the simulation of a pixelated charge readout for time projection chambers, given the large number of channels that this technology employs. Here we present the first implementation of a full microphysical simulator of a liquid argon time projection chamber (LArTPC) equipped with light readout and pixelated charge readout, developed for the DUNE Near Detector. The software is implemented with an end-to-end set of GPU-optimized algorithms. The algorithms have been written in Python and translated into CUDA kernels using Numba, a just-in-time compiler for a subset of Python and NumPy instructions. The GPU implementation achieves a speed up of four orders of magnitude compared with the equivalent CPU version. The simulation of the current induced on $10^3$ pixels takes around 1 ms on the GPU, compared with approximately 10 s on the CPU. The results of the simulation are compared against data from a pixel-readout LArTPC prototype

The DUNE Far Detector Vertical Drift Technology, Technical Design Report

International audienceDUNE is an international experiment dedicated to addressing some of the questions at the forefront of particle physics and astrophysics, including the mystifying preponderance of matter over antimatter in the early universe. The dual-site experiment will employ an intense neutrino beam focused on a near and a far detector as it aims to determine the neutrino mass hierarchy and to make high-precision measurements of the PMNS matrix parameters, including the CP-violating phase. It will also stand ready to observe supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the standard model. The DUNE far detector implements liquid argon time-projection chamber (LArTPC) technology, and combines the many tens-of-kiloton fiducial mass necessary for rare event searches with the sub-centimeter spatial resolution required to image those events with high precision. The addition of a photon detection system enhances physics capabilities for all DUNE physics drivers and opens prospects for further physics explorations. Given its size, the far detector will be implemented as a set of modules, with LArTPC designs that differ from one another as newer technologies arise. In the vertical drift LArTPC design, a horizontal cathode bisects the detector, creating two stacked drift volumes in which ionization charges drift towards anodes at either the top or bottom. The anodes are composed of perforated PCB layers with conductive strips, enabling reconstruction in 3D. Light-trap-style photon detection modules are placed both on the cryostat's side walls and on the central cathode where they are optically powered. This Technical Design Report describes in detail the technical implementations of each subsystem of this LArTPC that, together with the other far detector modules and the near detector, will enable DUNE to achieve its physics goals
