Foil Experiment

14:15

Upstream Foil broke, remade upstream foil, but it is very fragile. Foil holder is likely to interfere with upstream Faraday cup, so any measurements with it will be done last, if possible.

Both foils are currently installed with the vacuum currently being applied. There may be some beam running this evening, even if only to check that everything works as expected.

17:00

Vacuum from transport line connected to main ring. Vacuum pressure increased and showed signs of out gassing. Too much moisture from components like glue and tape. Vacuum pressure will take overnight to reduce to safe levels for beam running.
