JLab: Fernando, Elton, Dan, Elke, Bill, Tim, Mark
CMU: Curtis, Yves
Reviewing the list at http://www.jlab.org/~elke/ActionItemTrackerHallD.xls .
CDC charge division
o couple tubes with resistor at far end
o want to try
o helps with pattern recognition
Cooling
o Curtis’s idea: blow cool air
o Fernando and Tim may test this
Straw tube configuration
o CDC and BCAL separation depends on DIRC or not
o about an inch of space in present configuration
o need also to make FDC smaller
o BCAL gives no pi/K separation, timing not good enough
o BaBar DIRC used 10 cm of rdial space
Elton: Need to look at photon conversions with the new geometry
