MEASUREMENTS OF DEUTERON AND PROTON RESPONSE FUNCTIONS OF DEUTERATED-CYCLOHEXANE AND CYCLOHEXANE SCINTILLATORS

The deuteron and proton response functions of deuterated-cyclohexane ( C6D12) and cyclohexane (C6H12) scintillators have been measured using a Am-241-Be neutron source. The deuteron response function of the C6D1 2 scintillator was measured al seven energies over the range 2.201-4.1 64 MeV whereas the proton response function of the C6H12 scintillator was measured at nine energies over the range 3.093-5.307 MeV. Within t he experimental uncertainties, the measured deuteron response function of the C6D12 scintillator agrees with the published data. The proton response function of the C6D12 scintillator, which was derived from de uteron and proton response function data of the C6D12 and C6H12 scinti llators, is given by: E-p = 0.017 + 0.881E(d) - 0.011E(d)(2) (E-p and E-d in MeV). The proton and deuteron light output ratio of the C6D12 s cintillator at 0.1-6.5 MeV energies was Found to be 0.53-0.51. The lig ht output ratio is in good agreement with the published value of 0.5 f or a typical deuterated scintillator. (C) 1998 Elsevier Science Ltd. A ll rights reserved.
