Ragan | General | Stochastic cooling and orbit problem | On 1 April by 5 pm, we could stop the stochastic
cooling after the stacking process and also
change the orbit of the Tl beam to centre. |

Ragan, Alex, Esther | General | No beam in ESR | The beam is coming from SIS but doesn't arrive
in ESR because the quadrupole magnets in
ESR have failed.
