Magnetised Iron Neutrino Detector

(MIND) Totally Active Scintillating Detector

(TASD)

R&D on photon detector technology Measurements we want to make:

� Test different photon detector technologies: Avalanche Photodiodes (APD), Geiger Mode APDs (GMAPD), Silicon photomutiplier (SiPMT), Multi Pixel Photon Counter (MPPC), Multi-anode Photomultiplier Tubes (MaPMT), Hybrid Photon Detectors (HPD).

� Measure light output, PE yield, quantum efficiency, cross-talk and effect on resolution in real operating conditions

� Put different PD in test beam

R&D on extruded scintillator: attenuation as function of length, fiber insertion, optimal geometry (ie. square vs triangular or segmentation and sampling rate)

RPC prototype for the

India Neutrino Observatory (INO)

Prototype detectorPrototype detector Build prototype to put in test beam to test all of the above,

validate Monte Carlo simulations and optimise design

Use of INO test stand in a beam

environment? Other magnets at CERN?

How big do we make test beam detector?

Default is ~2x2x4 m3 ie. ~10-3 of full MIND

Important to contain < 2 GeV

Test Beam FacilityTest Beam Facility Request test beam time at CERN (ie East Area at the CERN PS) for

dedicated Neutrino Detector R&D

Need to build up infrastructure: magnet, beam telescopes, …

Neutrino detector test facility: resource for all neutrino detector R&D

MIND (and TASD) TestsMIND (and TASD) Tests Measurements we want to make:

� Muon identification: building particle ID

likelihood functions based on test beam ID

Measure PID eff. vs length of track� Charge identification (as function of B-field

and length of track)� Optimal segmentation: transverse and

longitudinal

Neutrino Factory Near Detector R&D Neutrino Factory Near Detector R&D

Near detectors: need to measure neutrino flux and relevant background for far detector signatures (ie. charm production, charge mis-identification)

R&D programme1) Vertex detector options: hybrid pixels, monolithic pixels (ie. CCD,

Monolithic Active Pixels MAPS or DEPFET), strips or 3D detectors. Synergy with other fields such as Linear Collider and LHC upgrade developments. Put different detector types in test beam.

2) Tracking: scintillation tracker (same composition as far detector). R&D should be similar to far detector.

3) Other issues relating to near detectors: particle identification, calorimetry, magnet.
