Abstract
Abstract
The FAMU experiment aims at an indirect measurement of the Zemach radius of the
proton. The measurement is carried out on muonic hydrogen atoms (μH) produced through the
low-momentum (50–60 MeV/c) muon beam a the RIKEN-RAL μ- facility. The particle flux plays
an important role in this measurement, as it is proportional to the number of μH atoms
produced, which is the target of the FAMU experimental method. The beam monitor calibration
technique and results, presented here, are meant to extract a reliable estimation of the muon flux
during the FAMU data taking. These measurements were carried out at the CNAO synchrotron in Pavia,
Italy, using proton beams and supported by Monte Carlo simulation of the detector in Geant4.
