[Poltarg12] Beam line materials

[Christopher Keith]

Tony,

I looked at your list of materials found here:

https://clasweb.jlab.org/wiki/index.php/TF_RGC_PolTarg_V1


My comments:

-  You specify 15NH3 for the target sample.  I think we'll be using 
plain old 14NH3.

-  I can't confirm the composition of G10 fiberglass.  Where'd you find it?

-  You have one cell filled with NH3 and the other with ND3.  I assume 
this was intentional.

-  I edited the table at the end and placed an asterisk(*) next to those 
items that are in the direct path of the electron beam.


Chris
