PENTATRAP [1] is a Penning-trap experiment consisting of five traps used to measure mass-ratios currently reaching a relative uncertainty of close to 10−11. This allows for mass-ratio measurements of stable and long-lived highly charged ions with numerous applications, among others in neutrino physics [2] and tests of special relativity [3]. The systematic uncertainties stemming from environmental influences including the magnetic field, pressure and temperature fluctuations are being measured in order to find possible correlations to fluctuations in the cyclotron frequency of the trapped highly charged ions. This will determine if further stabilization, e.g. an active stabilization of the magnetic field with Helmholtz coils centered around the traps, will be necessary and to what extend.
