Measurement of neutron radiotherapy spectra in a tissue-equivalent phantom

A new technique was investigated for determining the changes in neutron radiotherapy spectra with position within a tissue-equivalent phantom at the National Accelerator Centre in the energy range 0 to 63 MeV. An deuterated liquid scintillator (NE230) was used as the neutron spectrometer for these measurements. The pulse height spectra measured using the NE230 scintillator were unfolded to give the neutron spectra. The results show beam hardening with depth into the phantom, which are consistent with other reported findings. The unfolding procedures used are described and the results of the tests performed to verify reliability are also presented and discussed.
