Thomas Chillery, Lizeth Morales, David Rapagnani | Setup - Beam Tuning and Prepare Chamber for Measurement at 3.45MeV 7Li - Morning of 23rd | On the morning of 23/02/18 we aimed to
complete beam tuning of 7Li at 3.45MeV.
At 8:43 CHUP = 7.2e-6mBar, CHDW |

Thomas Chillery, Tom Davinson, Raffaele Buompane, David Rapagnani, Lucio Gialanella | Setup - Beam Tuning and Prepare Chamber for Measurement at 3.0MeV 7Li | On 21/02/2018 we reattempted the beam tuning.
We expected this to be easier now the rogue
mylar is removed from the beamline. |
