An extension duct + TMP were connected at the bottom of the downstream side of the drifttube (deflectors are inside) -> Replaced with GV + NEG + extension duct + TMP. Two angle plates were removed from the support structure so as not to interfere with GV.

These were emails I wrote in 2012 when I was first setting up the new positron trap arrangement after each shift. 

If I find more than these, I'll upload to this elog entry.
