Abstract
A neutron depth profiling (NDP) device was developed on China advanced research reactor (CARR) of China Institute of Atomic Energy (CIAE). The CARR-NDP device uses cold neutron beams transmitted by a neutron guide from the cold neutron source of CARR, and it is composed of a neutron beam collimator, and a vacuum target chamber containing a beam stopper and a detection system. The neutron flux at 1 m from the end of neutron guide is about 4.8 × 108 n cm-2 s-1 under operating power of 15 MW. A standard reference material SRM-2137 sample and a multilayer film sample were utilized to verify the performances of the CARR-NDP device.
