X -Ray and Pressure Measurements on Helium Solids
… data obtained from experiments at the National Synchrotron Light Source at the Brookhaven National Laboratory are also presented here. The vacancy formation energy of fcc 4He at 10.4 cm3 /mol was obtained by two different methods. In addition, c/a ratios were determined to be ideal for hcp 4He …

Electron beam sizes and lifetimes at MAX II and MAX III
The MAX II and MAX III synchrotron light sources at MAX-lab provide synchrotron radiation for experiments in a wide variety of research fields. The synchrotron radiation is emitted by ultra-relativistic electrons circulating in electron storage rings. In this thesis the transverse and longitudinal …

Core-Level Photoemission Investigations of the Cadmium-Telluride(100) and Indium-Antimony(100) Surface and Interfacial Structures
Photoemission techniques, utilizing a synchrotron light source, were used to analyze the clean (100) surfaces of the zinc-blende semiconductor materials CdTe and InSb. Several interfacial systems involving the surfaces of these materials were also studied, including the CdTe(100)-Ag interface, the …

Optical instruments for characterization in the nano-scale
Optical (light-based) instruments are often some of the most precise in many fields, owing to the wide availability of stable and low bandwidth lasers such as those of HeNe and single mode solid state types. Rulers of nanoscale precision and accuracy can be built with such lasers as light sources. …
