The 21st international workshop on Next Generation Nucleon Decay and Neutrino Detectors (NNN22)

→ Asia/Tokyo
Hida City Cultural Communication Center

Hida City Cultural Communication Center
Description

The workshop aims to discuss future detectors for research on neutrino physics and nucleon decays. It will consist of invited and contributed talks and poster presentations addressing the topics below.

  • Proton decay

  • High intensity neutrino beams

  • Supernova neutrinos

  • Solar neutrinos

  • Atmospheric neutrinos

  • Reactor neutrinos

  • Large Detectors R&D

This workshop will take place in person in Hida-Furukawa, a neighboring town of Kamioka, from Wednesday 28 to Friday 30 September 2022.

  • There is a poster session on the first day, Sept. 28th.
    The size of your poster must be A0 or smaller.
    (Both portrait and landscape orientations are possible.)
    There is no facility to print the poster close to the venue. Therefore, please bring your printed poster.

  • The registration fee is 5,000 yen, and we will collect at the venue.

  • A post-workshop excursion to Super-Kamiokande, KamLAND, and the Hyper-Kamiokande underground construction site is planned on the final day.

  • You can watch the session for those who can not come to the venue. (You can not comment or ask questions.)
    Sept. 28 and 29 (Link to the broadcast)
    Sept. 30 (Link to the broadcast)

We look forward to welcoming you to Hida in September 2022.

        Demonstration of a modularised LArTPC equipped with pixelated readout and novel light detectors for the DUNE near detector

        The Deep Underground Neutrino Experiment (DUNE) will be using a combination of liquid argon time projection chambers (LArTPCs) with the aid of other detectors to measure neutrino oscillation parameters with unprecedented precision. In order to accommodate the high event rate from the intense neutrino beam, a modularised LArTPC is designed for the DUNE near detector. Therefore, the length of the TPC drift can be significantly reduced resulting in benefits of easily achievable high voltage requirement and clean signal from decreased charge diffusion and enhanced electric-field uniformity. Resistive material is used as field-shell to shape the electric field and to maintain high uniformity. It occupies minimal amount of active volume in the detector and avoids the risk of single-point failure. This LArTPC is equipped with revolutionary pixelated readout which enables true 3D projection of particle passages. The pixelated readout eliminates projection ambiguity presented in wire-readout LArTPCs and is well suited for busy detector environment as in the DUNE near detector. Each TPC also deploys novel light detectors to measure module-contained scintillation light signal with high position resolution and light yield. The modularised LArTPC provides defined volume for charge-light matching which is particularly useful to identify neutrino events in the DUNE near detector with high event-rate. This talk will present the latest design of this LArTPC for the DUNE near detector and the results of the benchmark modules operated in the last year.
