Revision as of 03:25, 19 June 2007
Experimenters: Doug Wells, Mark Mitchell, Tamuna, Oleksiy
Apparatus: File:Setup-6-15-07.jpg
Data Runs:
1. Paraffin layer of thickness 2x6.3 cm was used as neutron attenuator.
The ungated spectrum of gamma-rays emitted by Cf-252 source is presented in Fig. 1.1.
Spectrum of gamma-rays emitted by Cf-252 source gated by the signal from plastic scintillator BC-420 is shown in Fig. 1.2.
Spectrum of time intervals between signals coming from germanium detector and fast plastic scintillator is represented in Fig. 1.3. Ge-detector signal served as "start" signal.
Total spectrum of Cf-252 obtained using BC-420 plastic scintillator and HAMAMATSU photomultiplier tube.
2. Polyethelen doped with boron of thickness of 2x5 cm was used for neutron shielding.
The ungated spectrum of gamma-rays from Cf-252 source obtained using HPGe detector is shown in Fig. 2.1.
Spectrum of gamma-rays gated by by the signal from plastic scintillator BC-420 is presented in Fig. 2.2.
TAC spectrum for time intervals between signals from HPGe detector and fast plastic scintillator one can find in Fig. 2.3.
