## Introduction

**A 5-year R&D plan was originally prepared three years ago at the behest of MCOG**
**purpose: demonstrate practicality of a funding plan to accomplish the proposed NFMCC R&D program at the expected funding level**
**two funding levels were assumed for planning purposes**
**a baseline case of continued “flat-flat” funding at the $3.6M level**
**a more optimistic scenario where our funding was augmented to $4.0M per year**
**When originally presented, the MUTAC chairperson judged the plan to be “almost plausible”**
**this judgment has—so far—stood the test of time ******
**more seriously, we have been able to roughly maintain our technical progress despite being held at the baseline scenario for the past several years**
**and despite having no contingency**

## MICE Commitments

**US hardware responsibilities (ongoing) include:**
**two Cherenkov detectors (delivered)**
**tracker electronics + contributions to scintillating fiber tracker itself**
**two spectrometer solenoids**
**two RFCC modules**
**each comprising a coupling coil and four RF cavities**
**thin windows for LH****2**** absorbers**
**beam line monitors**

## 5-year Plan (Original)

**Activities lumped into four broad categories**
**Cooling****: MuCool component R&D**
**MICE****: purchase or fabrication of components for the experiment**
**Targetry****: development of high-power targets and collection systems, including beam tests at BNL, CERN, or elsewhere**
**System studies****: work on acceleration, ring coolers, colliders, performance studies (e.g., IDS-NF)**
**Baseline case funding plan (****M&S only****) was**

| Activity | FY05 | FY06 | FY07 | FY08 | FY09 | FY10 |
| --- | --- | --- | --- | --- | --- | --- |
| Cooling | 492 | 345 | 345 | 705 | 615 | 225 |
| MICE | 300 | 620 | 635 | 700 | 790 | 1280 |
| Targetry | 713 | 640 | 625 | 100 | 100 | 100 |
| System studies | 195 | 195 | 195 | 295 | 295 | 195 |
| TOTAL | 1700 | 1800 | 1800 | 1800 | 1800 | 1800 |

## Assumptions

**Base program funds (i.e., staff costs) remain fixed**
**BNL = $0.9M**
**FNAL = $0.6M**
**LBNL = $0.3M**
**Completing ****MERIT**** was a priority in FY06-07**
**MuCool**** R&D coupling coil and (essentially identical) ****MICE**** coupling coils accounted for separately**
**but, recognized that MICE/MuCool split was flexible**
**“****Pessimistic” assumption of flat-flat funding at $3.6M**
**thus far has remained true ******
**with continuing resolution in place, FY09 not likely to be much different**

## What Has Changed

**Addition of ****ICST/Harbin**** as a ****MICE**** collaborator lowered cost of the three required coupling coil magnets ******
**$2.4M ******** $1.2M**
**Arrangements with D0 to use spare VLPC electronics permitted redirecting some of IIT’s NSF-MRI grant toward purchase of spectrometer solenoids ******
**DOE provided supplemental funds in both FY06 ($0.3M) and FY07 ($0.63M) in support of ****MICE**** ******
**NSF recently provided MRI ($0.8M, through U.-Miss.) to be used for ****MuCool**** and ****MICE**** magnets and RF cavities ******
**Delay in ****MERIT**** operations meant that funding roll-off was less steep than planned ******

## FY08 Funding Distribution

**FY08 ****NFMCC**** budget (only DOE-****NFMCC**** funds)****†**
**	****†****Also: salary support from BNL, FNAL, LBNL; support from NSF of $1M ($798K MRI + $133K 3-yr grant); support of Muons, Inc. via SBIR grants**

## Status

**Based on current estimate, there is a shortfall for ****MICE**** in FY08-09**
**with reasonable contingency expectations, need ~$1.5M for remaining work**
**present budget projects to only $1.2M**
**completion will depend on how much contingency is actually required**
**There is likelihood of slipping into FY10 to complete our cooling channel hardware responsibilities**
**spectrometer solenoid, tracker and CKOV obligations will be done on time**

## Update Process

**Now beginning process of creating a follow-on R&D plan**
**note that our existing major funding commitments (****MERIT**** and ****MICE****) should be satisfied by FY10 at the latest **
**Process:**
**Spokespersons and PM defining a list of R&D questions we believe should be answered in the next several years (in consultation with ****MCCC****)**
**influenced by needs of ****IDS-NF**** and desire to carry out Muon Collider ****feasibility study**** by FY12 (******** ~3x funding increase; see ****Shiltsev talk****)**
**these demands imply**
**substantial strengthening of simulation effort**
**enhanced emphasis on understanding NCRF cavity behavior in strong magnetic fields**
**renewed emphasis on Nb coated copper SRF cavities**
**proposals to answer questions will be solicited for TB evaluation in August**
**in consultation with ****MCTF****, TB and PM will develop plans and budgets for next few years (based on DOE guidance, if available)**

## Typical Candidate Activities

**Understanding behavior of “vacuum cavities” with magnetic insulation**
**open-cell or Be windows**
**“****Poor man’s” test of 6D cooling in ****MICE**
**“****Rich man’s” test of 6D cooling, e.g., FOFO snake, Guggenheim, HCC**

## Issues (1)

**Some aspects of the R&D plan are tightly linked to results from ****MuCool**** RF tests with coupling coil**
**expect initial results by the next MUTAC review**
**Presently difficult to get “long range” budget guidance from DOE for planning purposes**
**here, long range ******** 3–5 years**
**even getting guidance on next year has proved difficult recently**
**this problem affects the entire field, not just muon effort**
**Exploitation of ****MICE**** experiment requires post-docs, as does RF R&D program**
**shortage of effort will hamper progress**
**recruiting young people into our field has become increasingly difficult**
**participating intellectually in experiment and data analysis are important**
**simply providing the hardware must not be considered sufficient**

## Issues (2)

**SRF program “revival” will need expertise at Jlab + FNAL**
**will it be available?**
**Serious participation in ****IDS-NF**** and preparing RDR require significant engineering effort**
**ideally want Lab sponsorship for this**
**only some of this is expected to come from US (~$1M/year)**
**Completing ****feasibility study for Muon Collider**** in a timely way will likewise require substantial engineering resources**
**presently not clear there is much international interest in this goal**
**we need to work on this!**
**partnership with ****MCTF**** critical to success in this endeavor**
**Need for 6D cooling demonstration must be assessed**
**it will not be cheap; cost-benefit ratio must be evaluated**

## Issues (3)

**Presently, work on topics of interest to Neutrino Factory and Muon Collider not considered legitimate activity for core program funding**
**work toward high-field dipoles, aimed at DLHC or VLHC seemingly okay**
**work on high field solenoids, perhaps based on HTS, is presently not**
**Fermilab has partially addressed this with ****MCTF**** activities**
**BNL and LBNL staff would be interested in our challenges and I believe would participate more strongly if DOE gives its blessing**
**encouragement from MUTAC**** and P5 would help here**
**examples: magnets, NCRF, SCRF, lattice design and beam dynamics,...**
**SLAC could also be a help in several areas**
**NCRF, RF power source, lattice design and beam dynamics**
**such activities aimed at Muon Collider seem (to me) consistent with SLAC’s stated aim of pushing the energy frontier**
**it would be nice for DOE to encourage their participation in this national program**

## Summary and Outlook

**Execution of original 5-year R&D plan remains on track**
**this is due to a combination of luck and skill**
**not necessarily in equal proportions**
**NFMCC**** has maintained its focus on technical goals**
**Process of defining next phase of muon R&D program is under way*******
**Step 1: define questions, in consultation with ****MCTF**** management**
**Step 2: decide how to answer them (also with ****MCTF****)**
**Step 3: assess resource requirements ($, people, ****NFMCC/MCTF**** split)**
**Step 4: develop plan consistent with goals of NF RDR and MC FS by 2012**
**Step 4a: also try to get budgets into line with R&D needs**
**New R&D plan, ****agreed to by MCCC****, ready for review at next MUTAC meeting**
*******Note that MCTF**** ****has already begun this process**
