The Fermilab’s Mu2e experiment is designed to search for Charged Lepton Flavour Violation in direct, neutrinoless conversion of muon into electron in the presence of a nucleus’ electromagnetic field. Quantity, which is going to be observed is the ratio between the rate of the above BSM (Beyond Standard Model) reaction and the rate of the standard muon capture on the nucleus. The measurement precision is expected to reach up to 10-17. Mu2e-II is the codename for the second phase of the experiment planned to run with the lower energy, higher intensity primary proton beam provided by PIP-II accelerator, currently under construction. The ionization cooling with a wedge absorber is introduced to Mu2e-II setup for potential increase in the number of low momentum muons reaching the target. The study is made into the position and size of the wedge inside the beamline using G4Beamline simulation framework. Results show an increase up to 12% for muons with momentum P below 30 MeV/c and 7% for muons with P<40 MeV/c when the beam is measured right after the wedge. Further studies are necessary to investigate how this gain can be delivered to the stopping target.
