The DsTau/NA65 experiment aims to study 𝐷𝑠 → 𝜏 + 𝜈𝜏, 𝜏 → 𝑋 + 𝜈𝜏 differential production cross section in proton-tungsten interactions at CERN SPS. The emulsion detection technology is adopted to observe 𝐷𝑠 decays which have a small kink angle and a short flight length. The experiment will provide an independent ντ flux prediction for future neutrino beams with accuracy below 10%. Then, the systematic uncertainty of the ντ CC cross section measurement can be made sufficiently low to test LU in neutrino scattering. In 2021, the first physics run of the experiment was performed successfully. The collected data corresponds to 30% of the aimed total statistics. A target mover is designed and installed to the detector in order to have a uniform irradiation of the proton beam on the target surface. In this presentation, the performance of the target mover in 2021 run and the status of the experiment will be presented.
