The 3H/3He mass spectrometry experiment features two hyperbolical Penning traps and an external ion source in order to measure the Q-value of the 3H to 3He beta decay. The setup is designed to allow fast switching between 3H and 3He ions. This will enable us to decrease the dead time between cyclotron frequency measurements on the different ion species, which will in turn decrease the influence of magnetic field drift and other time dependent perturbations on the measured Q-value. This talk will focus on the challenges of single ion transport in a precision trap with high impedance electrodes.
