TP25: The NCNR MBE Facility for in-situ Neutron Scattering

J. A. Dura (NIST Center for Neutron Research)

A molecular beam epitaxy, MBE, facility has been built to enable in-situ neutron scattering measurements during growth of epitaxial layers. While retaining the full capabilities of a research MBE chamber, this facility has been optimized for polarized neutron reflectometry measurements. Optimization includes a compact, light weight, portable design, a neutron window, controllable magnetic field, large sample area with exceptional growth uniformity, and sample temperatures continuously controllable from 38 K to 1300 K. A load lock chamber allows for sample insertion, storage of up to 4 samples, and docking with other facilities. The design and performance of this chamber are described here.
