## Meeting with Hugh Montgomery and Jeff Appel18 August

- Update on the MINERA Collaboration
- Physics Goals
- Detector Design and Costing
- Real Estate Issues
- R&D
- Funding

## Detector Design Status - Kevin

- Physics (exclusive final states) requires sophistication
- Well along on design of strawman detector
- Core (fiducial volume) is solid segmented scintillator bars
- Take advantage of FNAL R&D program on extruded scintillator
- Outer detector for containment
- Magnetization strategy is key unsolved issue
- Outer detector is mechanically more complex as well
- Photosensors and electronics are potential cost driver
- MAPMT most likely (II/CCD still an option)
- Well into process of checking various options for electronics driven by past work at FNAL (MINOS, D0)

## Detector Design  - continued

- We will have a good handle on:
- Base design (strips, outer detector specs)
- Photosensors
- Electronics for photosensors
- Additional utility requirements for detector
- We will likely not have a good handle on:
- Installation costs
- “Collateral” costs of adding new utilities to the hall
- Optimizing for cost
- Schedule of installation and construction

## Real Estate Issues - NuMI/MINOS Near Hall

- Interested in the same piece of Real Estate
- (besides **MINER********A** :
- 1) Possibly the off-axis near detector
- 2) A prototype OPERA module

**Length Available for New Detector:****  ****26 m**
**Plenty of room for everyone...upstream of**
**MINER********A**

- Incoming angle:  beam: 58 mr.

## Funding Issues

- To be discussed on Sunday
