Mixing matrix parameters in a lepton sector are expected to be measured precisely by the next-generation experiments. One of them is an accelerator deep underground neutrino experiment DUNE, which will have a wide physics program in particular neutrino oscillations. Its main goal is to determine the neutrino mass hierarchy, the charge-parity phase $\delta_{\text{CP}}$ and the octant of mixing angle $\theta_{23}$. DUNE will consist of near and far detector complexes. The last one will measure neutrino spectra after oscillations. The near detector system will be used for controlling the systematic uncertainties. Two detectors of the near complex, LAr and GAr, will be able to move perpendicular on 33 m long to the beam axis and make precision reaction-independent spectrum measurements. Such design is named as DUNE PRISM and is unique relative to other existing experiments.
DUNE PRISM methods using a linear combination of near detector off-axis measurements are able to create far detector oscillated predictions without dependence on the model of neutrino interactions and fluxes. These uncertainties can unfold a bias of the far detector spectrum that effects directly on the experiment sensitivity to the oscillation parameters.
