The PENTATRAP experiment is under construction at the Max-Planck-Institut für Kernphysik Heidelberg. It aims for high-precision mass ratio measurements of long-lived and stable, highly charged nuclides with masses up to uranium with an accuracy of δ m/m ≈ 10−12. Primary goals are for example tests of quantum electrodynamics and neutrino oriented mass measurements. In order to reach the desired accuracy the PENTATRAP experiment contains a stack of five cylindrical cryogenic Penning traps and a dedicated detection system. The current status of the experimental setup will be presented.
