Abstract

In proton therapy facilities, high-energy neutron fields are generated as a consequence of (p,Xn) nuclear interactions. UPM has designed and tested its own extended-range Bonner Spheres Spectrometer (BSS) to support the development of this technology in Spain. This work shows the results obtained in the first experimental testing of this new BSS, using for the first time the ReBUNKI unfolding code in this kind of BSS. An intercomparison exercise with several unfolding codes has been carried out to validate ReBUNKI results and the new extended-range BSS response matrix.
