      abstract = {The precision in reconstructing events detected in a  dual-phase time projection chamber depends on an  homogeneous and well understood electric field within the  liquid target. In the XENONnT TPC the field homogeneity is  achieved through a double-array field cage, consisting of  two nested arrays of field shaping rings connected by an  easily accessible resistor chain. Rather than being  connected to the gate electrode, the topmost field shaping  ring is independently biased, adding a degree of freedom to  tune the electric field during operation. Two-dimensional  finite element simulations were used to optimize the field  cage, as well as its operation. Simulation results were  compared to <sup>83m</sup>Kr calibration data. This  comparison indicates an accumulation of charge on the  panels of the TPC which is constant over time, as no  evolution of the reconstructed position distribution of  events is observed. The simulated electric field was then  used to correct the charge signal for the field dependence  of the charge yield. This correction resolves the  inconsistent measurement of the drift electron lifetime  when using different calibrations sources and different  field cage tuning voltages.},
