New cross sections for the 27Al(p,x)7Be nuclear process: Monitoring proton beam energy via the 22Na/7Be cross-section ratio between 45 and 200 MeV

Cross sections are presented for 7Be produced in the proton bombardment of natural Al up to 200 MeV and compared with previous literature data. Cross-section ratios for the 27Al(p,x)22Na and 27Al(p,x)7Be nuclear processes are also presented in the energy region 45−200 MeV, exploiting our previously...

description Cross sections are presented for 7Be produced in the proton bombardment of natural Al up to 200 MeV and compared with previous literature data. Cross-section ratios for the 27Al(p,x)22Na and 27Al(p,x)7Be nuclear processes are also presented in the energy region 45−200 MeV, exploiting our previously reported cross sections for the 27Al(p,x)22Na process. The applicability for energy monitoring of proton beams by exploiting the 22Na/7Be cross-section ratio is discussed. Monte Carlo simulations in a simplified geometry provide additional information on activation of an Al monitor foil by secondary neutrons, indicating greater sensitivity to these neutrons by 24Na as a beam monitor than 22Na and 7Be.
