This paper introduces a new approach to measure the muon magnetic moment anomaly |$a_{\mu} = (g-2)/2$| and electric dipole (EDM) |$d_{\mu}$| at J-PARC facility. The goal of our experiment is |$a_{\mu}$| using an independent method with factor 10 lower momentum, 20 smaller diameter storage-ring solenoid compared previous ongoing |$g-2$| experiments unprecedented quality storage field. Additional significant differences from present experimental include 1000 transverse emittance beam...
A 10 kilo-tonne dual-phase liquid argon TPC is one of the detector options considered for Deep Underground Neutrino Experiment (DUNE). The technology relies on amplification ionisation charge in ultra-pure vapour and offers several advantages compared to traditional single-phase TPCs. 4.2 tonne prototype, largest its kind, with an active volume \three has been constructed operated at CERN. In this paper we describe detail experimental setup components as well report operation experience. We...

We have developed readout electronics for the central drift chamber (CDC) of Belle-II detector. The space near endplate CDC installation was limited by detector structure. Due to large amounts data generated CDC, a high-speed link, with greater than one gigabit transfer rate, required back-end computer. A new module satisfy these requirements. This processes 48 signals from converts them digital and transfers it directly All functions that via high speed link were implemented on single...

A high-intensity pulsed muon beam is becoming available at the Japan Proton Accelerator Research Complex (J-PARC). Many experiments to study fundamental physics using this are proposed. An experiment measure magnetic moment anomaly ($g-2$) and electric dipole (EDM) one of these it requires a tracking detector for positrons from decay. Fine segmentation required in tolerate high rate positrons. The time resolution be much better than anomalous spin precession period while buffer depth...
