The holder for the BeO foil had clearly melted. I added a tiny bit of green epoxy to the base of the target, hopefully this will provide a little more support in the future.
Also noticed 2 carbon foil targets had moved. Moved them back into position, and applied a little green epoxy to their base as well.
While I was in there, I did a visual inspection, and there are no cables,
wires, or tape in the beam path in any of the target positions.
