(VDGT,3CPRAEP) HI-13 tandem accelerator
(D-D) Neutrons were produced using a D2 gas target
bombarded with deuterons at 6.5, 8.0 and 9.5 MeV. The
current was 300 nA, the pulse repetition frequency
was about 3 MHz.
209Bi metal sample was 50 mm in diameter, 4 mm in
thickness, and 9.8 g/cm3 in density. Natural Ti
sample was 50 in diameter, 1 mm in thickness, and
4.54 g/cm3 in density.
(FPGAM,TOF) Time-of-flight method was used to
determine neutron energy.
(SCIN) A BC501A liquid scintillator detector was used
to monitor the neutron flux.
(HPGE) 4 Clover detector was used to measure produced
gamma-ray. Every detector was made of 4 high-purity
germanium crystals. The Clover detector was
calibrated with 152Eu, 60Co, 22Na and 133Ba standard
gamma-ray radioactive sources.
