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.

Ragan, Alex, Esther | General | Timing problem with SIS & ESR and problems with stacking | There are further problems with beam stacking
in ESR. It works occasionally but keeps failing.
There is also timing problem between SIS |

Alex, Esther | General | Beam in ESR lost | The beam in ESR was lost suddenly at ~22:20
due to a power supply failure of the quadrupoles.
