RESPONSE FUNCTION MEASUREMENT OF A DEUTERATED SCINTILLATOR USING A AM-241-BE SOURCE

The response function of 50 mm diameter deuterated (C6D6), plastic (NE 102A) and liquid (NE213) scintillators have been measured below 6 MeV deuteron/proton energies using a Am-241-Be source. Also the energy res olution of C6D6 scintillator was measured using a gamma-gamma coincide nt technique. The energy resolution of the C6D6 scintillator varies fr om 21.7 to 11.9% over 0.34-1.1 MeV electron energy range. The response function of the C6D6 scintillator agrees within 1-6% with that of Bov et et al. For the 50 mm NE102A and NE213 detectors, the response funct ions data agree with the published result of 125 mm NE102A and NE213 d etectors. In the energy range below 5 MeV, the light output of the C6D 6 scintillator is 17-24% lower than that of the NE213 detector. As the deuteron energy increases above 5 MeV, the difference between the lig ht outputs of the two detectors starts to decrease up to 9 MeV, where light outputs of both detectors correspond to the same electron energy . This trend in difference of light output of C6D6 and NE213 scintilla tor is consistent with the published results of light output for C6D6 and C6H6 scintillators.
