“…The neutron beam is collimated primarily by the LiF beam slit in the guide, and the beam area at the sample position is ultimately defined by the Cd collimator in the beam inlet port with a 10 mm diameter aperture. True integrated neutron flux at the sample position, which was estimated by an activation analysis of gold foil, is 7.37 9 10 6 n/cm 2 s, and the average wavelength of the cold neutron beam is 5.1 Å [5]. During operation, the target chamber is maintained at a vacuum of less than 2 9 10 -4 Pa (1.5 9 10 -6 Torr).…”

“…In the present study, determination of depth profiles for the BSi, LCO, and electrode samples was performed by using the KAERI-NDP software. A detailed description of the KAERI-NDP software has been published in [5] and only a brief review with information on added calculation features will be given here.…”

“…The first derivative of the 1472 keV high-energy edge of the SRM-93a was fitted to a Gaussian distribution function, and the standard deviation of the edge was estimated to be 7.76 keV. A more detailed procedure used to obtain the detector resolution is described in [5]. The Van Cittert iterative method [12] was applied to the deconvolution of the energy-broadened spectrum.…”

A neutron depth profiling system has been setup at HANARO, a 30 MW research reactor at the Korea Atomic Energy Research Institute. Silicon wafers containing 10 B or 6 Li, and electrode films from lithium ion batteries were irradiated with cold neutrons to test the performance and demonstrate the applications of the system. Depth profiles of 10 B and 6 Li were determined for each sample. The determined depth profiles were compared with reference values obtained by secondary ion mass spectroscopy. Peak depth, peak concentration, and aerial density agreed with the reference values to within 2, 6, and 11 % respectively.
