Fermilab Neutrino Program

Jim StraitNeutrino Discussion at CERN

Fermilab Accelerator Complex

LBNE

Ongoing Accelerator Upgrades

LBNE

Main Injector (being commissioned now): double beam power by stacking beam in the Recycler and decreasing

MI cycle time

Muon Campus (2013-2018): convert antiproton source to

meet needs of the muon program

Proton Improvement Plan (2012-2018): double beam power of the proton source

by increasing rep-rate

40 80 kW @ 8 GeV

350 700 kW @ 120 GeV

Next Accelerator Upgrades

New 800 MeV SRF, CW capable linac:

80 120 kW @ 8 GeV0.7 1.2 MW @ 80 -120 GeV

Ready before LBNE starts

Reorientation of “Project X” (now Proton Improvement Plan II) to focus on beam power for neutrinos.

0.8 to 3 GeV & 3 to 8 GeV linacsreplaces Booster1.2 2.3 MW @ 60 -120 GeV

~5 years years later

Plan to be presented at P5 meeting, 16 Dec at BNL

U.S. neutrino program

• Accelerator based Neutrino Experiments

using Fermilab Accelerators

T2K ICARUS …

• Reactor based Daya Bay, Double CHOOZ, …

• Neutrino-less double beta decay EXO, MAJORANA demonstrator, CUORE, …

Topic for this presentation

Neutrino Program (both n and n beams)

• Measure and characterize the pattern of neutrino masses and mixings:

MINOS / MINOS+ NOvA LBNE• Discover if the situation is more complex than 3 neutrinos with

Standard Model Interactions:

MINOS / MINOS+ NOvA LBNE MiniBooNE MicroBooNE

Proposed: ICARUS, LAr1-ND nSTORM• Neutrino interactions / cross sections and neutrino engineering

measurements that make the above points possible:

MiniBooNE MINERvA MicroBooNE LBNE ND / Proposed: ICARUS, LAr1-ND nSTORM
