INC-SOURCE (D-T) Tritiated titanium (Ti-T) target was bombarded 2321600100015
with a 350 keV d+ beam at the 0 degree beam line of 2321600100016
the Fusion Neutronics Source (FNS) at the JAEA. 2321600100017
To reduce the background at the measuring position, 2321600100018
the neutron collimator (2 cm diameter) at the 0 degree 2321600100019
beam line was used. The angle between the d+ beam and 2321600100020
the axis of the collimated neutron beam was 80 degree, 2321600100021
which resulted in a 14.2 MeV neutron energy. 2321600100022
The distance between an exit of the collimator and the 2321600100023
sample was 15 cm. 2321600100024
INC-SPECT The typical value of neutron fluence at the sample 2321600100025
position was 6.5E+5 n/cm**2/s. 2321600100026
DETECTOR (HPGE) 36% HPGe detector - to measure induced activity.2321600100027
The distance between the sample and the HPGe detector 2321600100028
surface was 5 cm. 2321600100029
SAMPLE Samples were 1 mm thick rectangular (10 mm x 20 mm) or 2321600100030
disk-shape (15 mm diameter). 2321600100031
