On Jan. 9 we did the PIE on Ta#66. Opened the heat shield and removed the EE. The inside of the heat shield was very black with lots of flakes falling off. The target itself looked overheated, and the container looked pretty bad for a Ta target. The outside of the EE looked perfect but after removing it there was a lot of black stuff on the side and we saw that the Re foil was curled up. Jens said during the runtime that he saw something that looked like a wire in the beam path, so maybe this was it. |
