Meeting with Hugh Montgomery and Jeff Appel18 August

Update on the MINERA 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 MINERA :

1) Possibly the off-axis near detector2) A prototype OPERA module

Length Available for New Detector: 26 mPlenty of room for everyone…upstream of

MINERA

Incoming angle: beam: 58 mr.


Funding Issues

To be discussed on Sunday
