Hello,
I looked at our anode wire under the electron microscope today. I took a piece of wire before and a piece after winding.
Unfortunately the operator was rather stressed and didn't have a lot of time, so we looked at both pieces simultaneously, i.e. I do not know which one is which.
Since it is only allowed to attach 3 files, I put the pictures under:
http://www.physi.uni-heidelberg.de/~adler/TRD/pics/
1st wire:
Anode1.tif (2000x)
Anode1a.tif (4000x)
2nd wire:
(each also with 2000x and 4000x at 2 differnt places on the wire)
Anode2.tif
Anode3.tif
Anode4.tif
Anode5.tif
Altogether it seems that wire 1 is smoother than the 2nd wire which has those bumps. But I guess it is hard to judge whether this wire was modified by winding, or whether the differences are just becasue its a different piece of wire.
cheers,
Clemens
