## Neutrino Factory – The Physics Case

**Neutrino Factory – The Physics Case**

**We Don’t Know – **
***But***** **
**There is a Natural Decision Point**
****** ****2012**

**After NOvA and T2K**
**If********13**** not seen**
**or**
**seen at 3******
**Consider New Facility**

**In order to make an informed**
**decision whether or not a NF is this new facility –**
**Will need a CDR ready at this time**
**This defines the R&D Program**

- Alan Bross NFMCC DOE Briefing Jan 2007

## Conclusions

**The Muon Collider as a mid-Term Priority for DOE?**
**The MC may be the way towards Lepton-Lepton collisions at the Energy Frontier**
**Will require increased effort on our part to make the technical case and increased support**
**Design and Simulation**
**Experimental verification of the many emerging new ideas**
**Synergy with the Neutrino Factory remains**
**Phased Approach to a Muon Complex looks promising**
**Neutrino Factory**
**Compelling case for a precision neutrino program remains**
**With present assumptions Neutrino Factory out-performs other options.  However, more is needed before concluding this is the right path**
**What the on-going Neutrino Physics program tells us**
**Must Remain an Option – IDS delivered CDR by 2012**

**We Find Ourselves in Interesting Times**

## Outlook

**As you are all aware, this has been a very tough year and next year looks scary **
**We still have managed to make good progress, but this situation is certainly limiting what we can do**
**There is also a great deal of uncertainty (and opportunity)**
**P5 Report**
**HEPAP’s Reaction to P5 Report**
**DOE’s Reaction to HEPAP Reaction to P5 Report**
**And There will be more reviews**
**Horizontal AARD DOE review this summer**
