Re: New prototype + wiring test

[Gerard Visser <gvisser@indiana.edu>]

Hi Yves,
	Congratulations - these are beautiful results! You guys have been 
working very hard I see. I hope that the 4.5 inch wiring can be held for 
the full detector, this will be excellent if it can be so.
	What is the length of the straws in the little prototype?

	Gerard
