keyword=12C foil moved form 20 cm to 10 cm down stream.
11:30-12:30 During controlled access, we (Xiaochao and J. P.) checked the target chamber and moved the 3rd 12C foil from 20 cm down-stream to 10 cm downstream. We found that the 3rd 12C foil holder was hit by beam and partially melted. No visible beam hitting spot seen view from the upstream side.
Thile installing the foil into the downstream 10 cm slot, I broke the foil.
So I used one of the old foils and installed into the slot.
