Danyal | General | setting up ESR | The operators are still busy extracting the
beam from the SIS18 towards the ESR and injecting
it into the ESR. |

Danyal | General | instabilities in ion frequency | The ion beam moves around, pretty arbitrary.
See picture.
ESR crew believes that it is not due to fluctuations |

Lars | General | instabilities in ion frequency | looks like the E-Cooler is responsible for
this. If one turns off the electron current,
the beam stays stable.
