Proposal for characterization of muon spectrometers for neutrino beam lines with the Baby MIND

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.
