FACILITY (CCW,3CPRNPC) The K-400 Intense Neutron Generator 3270500100009
SAMPLE Two samples (ThO2 powder of 99.95% purity) and monitor 3270500100010
aluminum (thin Al foil of 99.99% purity) were made 3270500100011
into round disks with a diameter of 2.0 cm; the 3270500100012
thickness of samples was 1.0 mm and 1.3 mm, and the 3270500100013
thickness of Ni and Zr was 0.3-0.5 mm. 3270500100014
The samples were placed at 50-135 deg. angle relative 3270500100015
to the deuteron beam direction and centered about the 3270500100016
target at distances of 3.5 cm. 3270500100017
INC-SOURCE (D-T) A deuteron beam of 220 keV and beam current of 3270500100018
350 mA used. The solid tritium-titanium target used 3270500100019
in the neutron generator was about 2.18 mg/cm. 3270500100020
DETECTOR (HPGE) A calibrated GEM-60P coaxial HPGe detector were 3270500100021
used with 70.1x72.3 mm in diameter and length. And the 3270500100022
relative efficiency is around 68%, and the energy 3270500100023
resolution is around 1.7 keV (FWHM) at 1.33 MeV. 3270500100024

The cross section of monitor reaction was determined by3270500100027
interpolation of the evaluated values of the reference.3270500100028
ERR-ANALYS (ERR-T) Total uncertainty 3270500100029
(ERR-1) Detector efficiency at 5.5 cm (~2%) 3270500100030
CORRECTION Corrections were made for gamma-ray self-absorption in 3270500100031
the sample, for coincidence sum effect of cascade 3270500100032
gamma-rays, and for geometry correction factor. 3270500100033
