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.
