The paper presents and discusses the results of studies using activation techniques. Using activation foils from the SWX-1552 kit (Shieldwerx, USA), an iterative grid method for reconstructing the neutron spectrum was tested. It was found that the use of activation foils for determining the spectrum of epithermal neutrons is questionable, since the main part of the interaction falls on the high-energy part of the spectrum, instead of the resonance of the foil. The number of neutrons is equal to the number of activated beryllium-7 nuclei (it has been proven by measurements that beryllium-7 is not sputtered from the lithium layer). The neutron yield was monitored by registering gamma quanta from the 7Li(p, n)7Be reaction. Depending on the number of registered gamma quanta, recalculation was made for the amount of activated beryllium. In this paper it was measured the number of neutrons depending on different geometries, different parameters of the proton beam and target material, there is a good agreement with the theory.
