The T2K experiment is a long baseline neutrino oscillation experiment. Its main goal to measure the last unknown lepton sector mixing angle θ13 by observing νe appearance in νμ beam. It also aims make precision measurement of known parameters, Δm232 and sin22θ23, via disappearance studies. Other goals include various cross-section measurements sterile searches. uses an intense proton beam generated J-PARC accelerator Tokai, Japan, composed beamline, near detector complex (ND280), far...
We present the case for a dark matter detector with directional sensitivity. This document was developed at 2009 CYGNUS workshop on detection, and contains contributions from theorists experimental groups in field. describe need sensitivity; each experiment presents their project's status; we close feasibility study scaling up to one ton detector, which would cost around $150M.
A new Micromegas manufacturing technique, based on kapton etching technology, has been developed recently, resulting in further improvement of the characteristics detector, such as uniformity and stability. Excellent energy resolution obtained, reaching 11% FWHM for 5.9 keV photon peak the55Fe X-ray source 1.8% (with possible evidence less than 1%) 5.5 MeV alpha 241Am source. The Microbulk detector shows several advantages like flexible structure, low material high radio-purity, opening thus...
A new type of radiation detector based on a spherical geometry is presented. The consists large gas volume with central electrode forming radial electric field. Charges deposited in the conversion drift to sensor where they are amplified and collected. We introduce small located at center acting as proportional amplification structure. It allows high gains be reached operates wide range pressures. Signal development absolute amplitude response consistent predictions. Sub-keV energy threshold...
The ILD detector is proposed for an electron-positron collider with collision centre-of-mass energies from 90~\GeV~to about 1~\TeV. It has been developed over the last 10 years by international team of scientists goal to design and eventually propose a fully integrated detector, primarily International Linear Collider, ILC. In this report fundamental ideas concepts behind are discussed technologies needed realisation reviewed. document starts short review science goals ILC, how can be...
In this document, we present the Technical Design Report of Upgrade T2K Near Detector ND280. The goal upgrade is to improve performance measure neutrino interaction rate and constrain cross-sections so that uncertainty in number predicted events at Super-Kamiokande reduced about 4%. This will allow physics reach T2K-II project. achieved by modifying upstream part detector, adding a new highly granular scintillator detector (Super-FGD), two TPCs (High-Angle TPC) six TOF planes. Details...
The aim of the MIMAC project is to detect non-baryonic Dark Matter with a directional TPC using high precision Micromegas readout plane. We will describe in detail recent developments done bulk detectors as well characterisation measurements performed an Argon(95%)-Isobutane(5%) mixture. Track alpha particles be shown.
MIMAC (MIcro-TPC MAtrix of Chambers) is a directional WIMP Dark Matter detector project. Direct dark matter experiments need high level electron/recoil discrimination to search for nuclear recoils produced by WIMP-nucleus elastic scattering. In this paper, we proposed an original method electron event rejection based on multivariate analysis applied experimental data acquired using monochromatic neutron fields. This shows that 105 power reachable discrimination. Moreover, the efficiency was...
A gas Time Projection Chamber can be used for gamma-ray astronomy with excellent angular-precision and sensitivity to faint sources, polarimetry, through the measurement of photon conversion $e^+e^-$ pairs. We present expected performance in simulations recent development a demonstrator tests polarized beam.
