October 7 minutes

Quick minutes summary:

We had a very interesting discussion of the issues associated with 1-d versus 2d readout in a fine-grained calorimeter for the NUMI Off-axis beam, led by Carl Bromberg. Although we've been hearing quite a bit about scintillator options and also RPC's, there is also the possibility of using iarocci tubes for the readout as well.

Furthermore, Kirk McDonald showed an addition to the document which concerns the possibility of putting a liquid argon near detector in the numi beamline to do early measurements on cross sections, while getting experience with this detector technology on the short time scale.
