The deepest probe of Lepton Flavor Physics: Ultra-rare m-Decays:

First Order FCNC:

Higher order dipole “penguin”:

Virtual n mixing

The MEG(PSI) experiment has probed to 10-11 level.

Forbidden in Standard Model

Observation of neutrino mixing shows this can occur at a very small rate

Photon can be real (m->eg) or virtual (mN->eN)

Cost and schedule

Cost and Schedule

  • This is a technically limited schedule

  • Critical Path is Superconducting Solenoids

  • $200M “fully-loaded” Total Cost

data-taking 1st quarter Calendar 2016

Muon g-2 @ FNAL

  • Based on results of the August 2010 Intensity Frontier review, DOE has decided to go ahead with the next generation muon g-2 experiment by moving the storage ring from Brookhaven to Fermilab.

  • Fermilab can deliver 21x the total Brookhaven statistics in less than 2 years.

  • Modest modifications of existing beamlines and detectors allow us to drastically reduce the dominant systematic errors in the precession frequency measurement.

  • This is matched with a world wide program to validate the SM calculation of g-2 (Novosibirsk, KLOE, B-factories, BES. Lattice…)

  • Currently reevaluating the schedule given budget constraints but expect to start taking data in the middle of this decade.

Project x talk proper

Project-X talk proper

  • Kaons as part of Project-X are a direct result of the CW option ( as are the nuclear physics options). Much higher intensities result from the CW option.

  • CW option is a result of the push to do ADS using project-X. 2007 Accel Division Seminar I gave on ADS mentioned CW. It was picked up by several attendees and Option 2 was born.

  • AHIPA09 workshop further cemented the broad base of physics possible using a CW Project

  • ADS as part of Project-X was further strengthened at the Accelerators for America’s future Workshop held by the DoE.

The project x research program

The Project-X Research Program

  • Long baseline neutrino oscillation experiments:

    Driven by a high-power proton source with proton energies between 50 and 120 GeV that would produce intense neutrino beams directed toward massive detectors at a distant deep underground laboratory.

  • Kaon, muon, nuclei & neutron precision experiments driven by high intensity proton beams running simultaneously with the neutrino program:

    These could include world leading experiments searching for muon-to-electron conversion, nuclear and neutron electron dipole moments (edms), and world-leading precision measurements of ultra-rare kaon decays.

  • Platform for evolution to a Neutrino Factory and Muon Collider

  • Synchrotrons driving kaon physics programs.

    SPS (0.015 MW), JPARC (goal of >0.1 MW), Tevatron (0.1 MW)

  • Linear machines driving nuclear and neutron programs:

    SNS, LANL, FRIB….not providing CW light-nuclei beams.

Continuous wave cw linac for rare processes

“Continuous Wave” (CW) Linac for Rare Processes…

  • Beam extraction challenge is finessed.

  • Duty factor is very high.

  • The high frequency bandwidth intrinsic to a Linac can be exploited to generate excellent time resolution (dt~20psec), a very powerful tool to face a high intensity environment.

  • JLAB has demonstrated that beam can be cleanly multiplexed between many targets with minimal losses. These “touchless” RF beam multiplexers are enabled by the high linac bandwidth.

  • Excellent beam power scaling.

Road to future progress neutrino research program

Road to Future Progress: Neutrino Research Program

  • Strong international community. US community is healthy and growing.

  • Explicitly engage the Neutrino Factory community to explore and develop a design driven by Project-X—Leads to muon collider

  • Good opportunities for collaboration and leadership.

Road to future progress muon research program

Road to Future Progress: Muon Research Program

  • International community active, current Fermilab community is small, but growing with Mu2e and the possibility of (g-2)m.

  • No conceptual accelerator & beam design yet for driving next-generation mge conversion experiment beyond Mu2e and COMET at JPARC. A PRISM (FFAG) based solution needs further accelerator design work. Interesting synergies with Muon Collider cooling concepts are being explored that would clearly exploit Project-X.

  • Great opportunities for collaboration and leadership.

Road to future progress kaon research program

Road to Future Progress: Kaon Research Program

  • International community active, Fermilab community is dormant now. Buoyed to some extent now by the US quark flavor physics community—but this community is currently under stress regarding futures.

  • Excellent basis for 1000-event K+ gp+nnexperiment based on extrapolating techniques developed and demonstrated by BNL E787/E949 experiments.

  • Good basis for 1000-event KLgp0nnexperiment based on the KOPIO conceptual design developed for the BNL AGS.

  • Great opportunities for collaboration and leadership.

Summary

Summary

Project-X is a next generation high intensity proton source that will deeply reach for physics beyond the Standard Model and incisively probe of the origins of matter:

Neutrinos: An after-burner for LBNE that reduces the tyranny of

(Detector-Mass xRunning-time) by x3, and a foundation for a Neutrino Factory.

Rare Processes: Game-changing beam power and timing flexibility that can support a broad range of particle physics experiments.

Prospects: International collaboration formed, ongoing substantial US (DOE) investments in R&D (Project-X + SRF + ILC) on Super Conducting RF accelerator technology supporting Project-X.

Earliest construction start of 2015, operations in 2020.
