摘要：

The Cold Neutron Depth Profiling (CNDP) instrument at the NIST Cold Neutron Research Facility (CNRF is now operational. The neutron beam originates from a 16 liter D2O-ice cold source and passes through a filter of 13.5 cm of single crystal sapphire. The neutron energy spectrum may be described by a 65 K Maxwellian distribution. The sample chamber configuration allows for remote controlled scanning of 15 cm x 15 cm samples and varying of both sample and detector angle. The improved sensitivity over the current thermal depth profiling instrument has permitted the first nondestructive measurements of O-17 profiles. Results of some of the first sample measurements are presented.
