An EBIT as an Offline Ion Source for High-Precision Nuclear Mass Measurements

  • Client: Max Planck Institut für Kernphysik
  • Date of launch: Feb, 2010
  • Place: Heidelberg, Germany


The Dresden EBIT delivered to the Max-Planck-Institute for Nuclear Physics in Heidelberg is part of the PENTATRAP experiment. The objective of the experiment is to achieve high-precision mass measurements on highly charged stable and long-lived ions.

During the mass measurements, it is expected to reach relative accuracies of better than 1x10-11 which allows for tests of fundamental symmetries and the determination of fundamental constants. The aspired accuracy can only be reached by the use of highly charged ions. During the assembling and testing phase, the Dresden EBIT serves as an offline ion source for highly charged ions, having to fulfil specific requirements concerning reachable ion charge states and ion beam intensities.
