J-PARC Neutrino Beamline Upgrade Technical Design Report
- 2019
-
Rapport (refereegranskat)abstract
- In this document, technical details of the upgrade plan of the J-PARC neutrino beamline for the extension of the T2K experiment are described. T2K has proposed to accumulate data corresponding to 2×1022 protons-on-target in the next decade, aiming at an initial observation of CP violation with 3σ or higher significance in the case of maximal CP violation. Methods to increase the neutrino beam intensity, which are necessary to achieve the proposed data increase, are described.

Baby MIND : a magnetized segmented neutrino detector for the WAGASCI experiment
- 2017

Tidskriftsartikel (refereegranskat)abstract
- T2K (Tokai-to-Kamioka) is a long-baseline neutrino experiment in Japan designed to study various parameters of neutrino oscillations. A near detector complex (ND280) is located 280 m downstream of the production target and measures neutrino beam parameters before any oscillations occur. ND280’s measurements are used to predict the number and spectra of neutrinos in the Super-Kamiokande detector at the distance of 295 km. The difference in the target material between the far (water) and near (scintillator, hydrocarbon) detectors leads to the main non-cancelling systematic uncertainty for the oscillation analysis. In order to reduce this uncertainty a new WAter-Grid-And-SCintillator detector (WAGASCI) has been developed. A magnetized iron neutrino detector (Baby MIND) will be used to measure momentum and charge identification of the outgoing muons from charged current interactions. The Baby MIND modules are composed of magnetized iron plates and long plastic scintillator bars read out at the both ends with wavelength shifting fibers and silicon photomultipliers. The front-end electronics board has been developed to perform the readout and digitization of the signals from the scintillator bars. Detector elements were tested with cosmic rays and in the PS beam at CERN. The obtained results are presented in this paper.

Proposal for characterization of muon spectrometers for neutrino beam lines with the Baby MIND
- 2015
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Neutrino detectors based on state-of-the-art plastic scintillators read out with solid state photo-sensors, as well as new magnetization schemes, have been developed in the framework of AIDA. Meaningful size prototypes are under construction. In the framework of the CERN neutrino platform, we propose to test a Totally Active Scintillator Detector (TASD) and a prototype of a Magnetized Iron Neutrino Detector (MIND), called Baby MIND in the H8 beam line in 2016-2018. The design of the detectors and the purpose and plans for the beam tests are presented. An opportunity to use the Baby MIND detector in a real neutrino beam at JPARC for the measurement of the cross-section ratio between Water and scintillator (WAGASCI experiment) is described.
