NSLS-II Seminar

"A New Beamline for Surface and Interface Science at Diamond Light Source"

Presented by Dr. Tien-Lin Lee, Principal Beamline Scientist, Diamond Light Source, Oxford, UK

Wednesday, August 25, 2010, 2:00 pm — Large Conference Room, Bldg. 703

A new beamline for studying surfaces and interfaces is currently being constructed at Sector 9 at Diamond Light Source and is scheduled to have its first light in November 2011. It is designed to be a dedicated facility for high-resolution investigations of atomic structures and electronic properties of a wide range of surfaces and buried interfaces, under ultra-high vacuum or ambient conditions, using photoelectron spectroscopy (PES), x-ray standing waves, x-ray absorption spectroscopy, photoelectron diffraction and x-ray reflectivity. To apply the different techniques to the same sample, and to access a wide range of absorption edges, which can be highly beneficial for studying complex systems, the beamline will provide both soft and hard x-rays with two canted undulators installed in a modified long straight section, and is designed to have one end-station where a spot on the sample can be probed by both beams. Such a combination also offers a unique opportunity for hard x-ray PES experiments over a wide energy range. This presentation will be focused on the technical design, scientific cases and current status of the beamline, with an overview of the research activities of other beamlines in the Surface and Interface Village at Diamond.
