Resumo
Gamma-ray and neutron spectra from the
18O +76Se reaction at 15.3 MeV/u were measured with the
EDEN array of liquid scintillators at the LNS. The results
were compared to GEANT Hadrontherapy physics list simulations
in order to assess the reliability of this model for the
development of theNUMENproject.Agood agreement with
the shape of the experimental gamma-ray spectra and a reasonable
agreement with the total count rates were obtained.
The gamma spectra originated from the nuclear reactions
were selected by time coincidence with the Superconducting
Cyclotron radio-frequency reference signal. The random
coincidence background rate was appropriately described only when the Faraday Cup, the material and geometry of
the experimental hall and its contents were included in the
simulationwith sufficient detail. The information on the radiation
spectra is important for the adequate development of
the project of the detector arrays and electronic equipment
for the advanced phase of NUMEN. Since orders of magnitude
larger beam intensities are planned for this phase, the
random coincidence rate is also of significant importance,
particularly for the performance of the G-NUMEN gamma
calorimeter array.
