Abstract:
Tau neutrino is the least studied lepton of the Standard
Model (SM). The NA65/DsTau experiment targets to investigate D s , the parent particle of the ν τ , using the nuclear
emulsion-based detector and to decrease the systematic uncertainty of ν τ flux prediction from over 50 % to 10 % for future
beam dump experiments. In the experiment, the emulsion detectors are exposed to the CERN SPS 400 GeV proton beam. To provide
optimal conditions for the reconstruction of interactions, the protons are required to be uniformly distributed over the detector's
surface with an average density of 10 5 cm -2 and the
fluctuation of less than 10%. To address this issue, we developed a new proton irradiation system called the target mover. The new
target mover provided irradiation with a proton density of 1.01 × 10 5 cm -2 and the density fluctuation of
1.9 ± 0.3% in the DsTau 2021 run.
