The HANARO neutron reflectometer with horizontal sample geometry. Relocation and upgrade plans of the BNL H9-A reflectometer

초록

A new neutron reflectometer with horizontal sample geometry is under construction at a thermal neutron port at HANARO, the 30 MW research reactor at KAERI. It was originally designed and operated at the H9-A beam port at Brookhaven National Laboratory (BNL), and was relocated to HANARO in 2004. It will be initially installed at the ST3 thermal-neutron port without any significant modification, and significant improvements in structure and performance are planned when the new cold source is installed in 2008. If successfully installed, it will be the first reflectometer in Korea for the study of free surfaces, which is currently lacking. For the thermal source, the feasible wavelength of incident neutron beam is 2.5 angstrom and this would permits the q ranges up to 0.21 angstrom(-1). (c) 2006 Elsevier B.V. All rights reserved.
