### Description

A design option considered for the inner tracking volume of the System for on-Axis Neutrino Detection (SAND) in DUNE is a single Straw Tube Tracker (STT). The STT is designed to offer a control of the configuration, chemical composition and mass of the targets similar to the one achieved in electron experiments. Thin layers (~1-2% radiation lengths) of interchangeable target materials (mostly H$_2$ and C) alternate with straw layers representing about 97% of the total mass. A thin Liquid Ar target located upstream of the STT. The STT allows to select $\nu(\bar \nu)$ CC interactions on H using a kinematic analysis in the plane transverse to the beam direction. The availability $\nu (\bar \nu)$-H allows the determination of $\nu_\mu$ and $\bar \nu_\mu$ relative fluxes with better than 1%. A comparison between CC interactions in Ar and H within the same detector provides direct constraints on nuclear effects in Ar.
