You were right -- the setup was like this:
d beam ---> | thin foil | ---> MeV particles ---> | Si detector |
So the low energy d's entered the thin foil from the left and energetic
particles exited from the right, through 1 um of substrate (which I think
can easily stop a 350 eV beam). I was just pointing out that there was no
detector on the lefthand side as well; if there was one, perhaps particles
would have been detected.
