## Report on the Mini-Review of theImpact of  on Fermilab.Monday, March 29, 2004

- A Fermilab internal mini-review was conducted on Monday March 29, 2004 to assess the issues and impact of approval of the MINERvA experiment on Fermilab and on the MINOS
- experiment.
**The committee: **Mike Crisler (chair), Kurt Krempetz, Qizhong Li, Bill Louis, Doug Moehs, Rich Stanek
**PAC Observers: **Jim Alexander, Jim Brau, Heidi Schellman
- Presentations:
- Summary of Physics Goals - Jorge Morfin
- Detailed Description of Detector - Kevin McFarland
- Impact on the MINOS experiment - Stan Wojcicki
- The MINOS near detector hall - what is there, what does MINOS need - Dave Pushka
- What does MINERvA need? Impact on Fermilab - Peter Shanahan

## Summary from Impact Review Committee

- 1   The committee did not identify any unusual safety issues.
- 2. The sense of the committee is that the Minerva collaboration has provided a fairly complete analysis of the resources they will require from Fermilab, but some omissions were noted. We would estimate that when the analysis is more fully refined, that the base cost to Fermilab will likely increase by of order 40%, and that a contingency of 40% would be appropriate. The proposed schedule is somewhat tight, which may lead to less than 4 years of running.
- 3. The sense of the committee is that the MINOS experiment will likely benefit from the information provided by Minerva, and that we do not anticipate any significant negative impact from either the installation or running of Minerva on the operation of MINOS. Minerva intends to run parasitically to MINOS and make no independent beam requests. It is likely that interactions in the Minerva apparatus will contribute a few percent additional deadtime to the MINOS near detector.

## Summary from Impact Review Committee - continued

- 4. There is an issue with the availability of cooling in the MINOS cavern. The
- preliminary Minerva estimates assumed the nominal estimated rates of water flow
- into the cavern. Recent measurements have shown that the actual flow rate is 240
- gpm instead of the expected 300 gpm. This new information was not available to
- Minerva during their preparations for this review. The sense of the committee is this
- is not a major issue, but it will necessitate the additional cost of larger heat
- exchangers.

## New Fermilab Impact Items

## Have we double-counted?

- Summary Point 2.
- The sense of the committee is that the Minerva collaboration has provided a fairly complete  analysis of the resources they will require from Fermilab, but some omissions were noted. We would estimate that when the analysis is more fully refined, that the base cost to Fermilab will likely increase by of order 40%, and that a contingency of 40% would be appropriate.  The proposed schedule is somewhat tight, which may lead to less than 4 years of running.
- By adding 40% to our original (MINOS-cost based estimates) to cover omissions and then
- adding new impact items on top of that, are we double counting?
- If we take our original estimates (before applying the factor of 1.4) and adding the new requests we have:
- 		Sum total before contingency		$1857 K
- 			            contingency		$  742 K
- 				Sum total		$2599 K
- 		compared to			$3189 K
