Ragan, Yuri, Danyal | Accelerator | Problem in UNILAC | The power supply of the UNILAC magnet is broken.
The repair will take up to 6-7 hours. |

Carsten | Accelerator | New Cooler voltage after the crash of the cooler | After the restart of the cooler the Ohmlabs
divider showed a voltage 16V lower than before.
This could also be seen as a slight shift |

Carsten | Accelerator | Maintanence UNILAC / Op training | We had no beam since about 1000. Also, we
are still trying to find out why we have
such a low intensity in the expereimnt.
