## 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 wheter or not a NF is this new facitily –**
**Will need a TDR ready at this time**
**This defines the R&D Program**

## Conclusions

**Neutrino Factory**
**Compelling case for a precision neutrino program**
**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**
**Process must include cost and schedule considerations**
**International Design Study**
**Muon Collider**
**New concepts improve the prospects for a multi-TeV Muon Collider**
**Many new ideas emerging**
**Front-end is the same as for a Neutrino Factory**
**First full simulation of required cooling has been competed**

**The Collaboration has entered a very exciting phase**

## Outlook

**As you are all aware, our funding situation has been very tight and remains so.**
**Has certainly limited what we can do**
**However, given our recent MUTAC reviews and the recommendations of the Advanced Accelerator R&D Panel**
**We are on solid ground in asking for increased funding**
**And at our DOE briefing meeting in March we will make a strong case to the Office of High Energy Physics to follow the AARD Panel’s recommendation**
