Abstract:
The high-precision Penning-trap mass spectrometer PENTATRAP is currently being revised at the Max-Planck-Institut für Kernphysik in Heidelberg. It uses five Penning traps with the goal to reach a relative uncertainty in mass-ratio determination below δm/m≈10−11. The first commissioning phase revealed the necessity to modify the cryogenic setup in order to increase the storage time for highly-charged ions. A pre-vacuum chamber will be implemented as well as a pumping barrier to separate the beamline vacuum from the high vacuum region of the traps.
