Notes from this meeting:

• Argonne has completed Bubble Chamber safety reviews.

• GEANT4 simulation of the radiator thickness has been updated. We will go with 6 mm thickness; please let us know if you have another choice.

• Need a plan to deal with Earth's field. Wrapping the beamline with mu-metal might complicate the problem.
