More noise studies

Hall D Electronics:

Hi All,

More noise studies concerning the CDC can be on the usual place:

http://www.jlab.org/Hall-D/software/wiki/index.php/CDC_06_02_2008

in section 5

Apparently it is not the Al-foil shielding but the connection preAmp 
ground to the shieding around the end-plenum (that was already there, see 
pictures) that has the largest effect on the noise.

Cheers,
 	Yves
