Timeline towards RDR o Steps towards finalising the RDR (and tasks for Euro. Nu): Euro. Nu, RAL, 21 January 2011 5

Detector R&D Plan (beyond RDR) o Magnetisation: – Superconducting Transmission Line (STL) for MIND o Photodetectors: – Worldwide R&D for Si. PMT is well advanced Euro. Nu, RAL, 21 January 2011 6

Detector R&D Plan o Scintillator: – Square vs triangular cross-sections – Engineer detector plane mechanics – Co-extrusion fibre-scintillator o Reliance on single manufacturer for fibres – Kuraray currently is the only manufacturer in the world that can deliver WLS fibres of consistently good performance – There is a risk associated with this: do we need academic+industrial R&D into developing alternate fibre technology? Euro. Nu, RAL, 21 January 2011 7

Detector R&D Plan o Investigation alternate readout for MIND (in collaboration with INO) – Magic baseline requirements are not as demanding so a magic baseline detector such as INO with RPC readout might be suitable – cost implication o Prototyping: – We need to benchmark performance of MIND and near detector – Prototype MIND: study muon charge identification, hadronic energy, hadronic angular reconstruction, scintillator+Si. PMT readout – Prototype TASD or scintillating fibre detector in B-field: electron charge misidentification – Could also test liquid argon in B-field and water Cherenkov prototype Euro. Nu, RAL, 8 – This will be done in AIDA (H 8 21 test beam at CERN) January 2011

AIDA o o AIDA (Advanced Infrastructures for Detectors at Accelerators): European project to develop detector R&D for LHC, ILC/CLIC, neutrino facilities and Super. B facilities Neutrino activities inside AIDA: develop test beam area in H 8 beamline (North Area at CERN) – A study of the upgrade of the H 8 beam to deliver electrons, muons and hadrons for neutrino experiment prototypes will be delivered – Build a Magnetised Iron Neutrino Detector (MIND) prototype (2 x 2 x 4 m 3) – Install a Totally Active Scintillating Detector prototype inside the Morpurgo magnet – This will allow to test both electron and muon charge ID in the same test beam – Apart from the equipment, detectors and electronics we would also need to provide a DAQ. – Refurbishing the cryogenics infrastructure in the H 8 beam to allow Euro.

AIDA: H 8 beamline o Totally Active Scintillator prototype in Morpurgo magnet: electron charge ID test o Magnetised Iron prototype: 4 m beam B=1 T 2 m 2 m iron (3 cm) scintillators (2 cm) Euro. Nu, RAL, 21 January 2011 11

H 8 beamline o Test beam activity with TASD and MIND prototypes: Euro. Nu, RAL, 21 January 2011 12

H 8 beamline o MIND will become an integral part of infrastructure and is used as muon catcher and spectrometer, for testing other prototypes (water Cherenkov, liquid argon, etc. ) Euro. Nu, RAL, 21 January 2011 13

Conclusions o o First draft of IDR ready: comments from community by 20 February 2011, final version by 7 March 2011, ready for review in May List of tasks that need to be addressed for the RDR identified and a timeline defined Beyond the RDR: R&D plans to develop hardware solutions also identified AIDA will help in R&D prototyping: testbeam at CERN for low energy detector tests ― MIND and TASD prototypes will be built that remain in test beam as infrastructure of the facility for other users Euro.
