  1. Fast detectors for magnetized near detectors in Superbeam, beta-beam, neutrino factory MICE calorimeter = 1m3 Accurate position resolution (mm)  triangular shaped scintillator bars Magnetic field  si-PMT readout First test in T9 beam last week: Next step: test at CERN in Dipole magnet in H8)  Variable density by spacing planes -- reconstruction of showering electrons -- stopping properties of pions and muons

  2. Materials For 48 planes of 64 scintillator about 1m long bars -- scintillator: assume Fermilab can provide as for EMR -- SiPM and electronics in a first iteration can use spaers from the T2K EMCAL (contacts D. Wark, C. Touramanis) -- ibid for electronics with 48 front-end and 2 back end boards. -- not fast electronics (not suited for MICE beam, OK for CERN beam) Construction in independent planes mounted on a extendable frame, allowing density from 1 to ~0.4 (air gaps) Aims: -- expose to 250 MeV/c to 10 GeV/c particles (e, pi, mu) Charge ID for electrons, stopping ID for charged mu and pi and protons. Interactions of pions Shower energy and angle? -- contact at CERN with Ilias Efthymiopoulos (NEU2012) for beam line. To be checked: incoming particle ID. (TOF, CKOV) For stopping particles could prefer MICE beam.

  3. Following steps: -- use same or similar planes as detector for MIND situated outside magnet -- develop cheap electronics to envisage mass prodiction -- develop >15 m long scintillator bars Requests from this group: -- software for test beam simulation and analysis -- simulation of electrons in density d=1, ½, 1/3 -- which is your predicted optimum?
