Abstract
This paper will discuss a microscope that allows high energy resolution spectroscopy to be performed at high spatial resolution. This instrument uses a high magnetic field to contain and focus electrons emitted from the sample surface and has a two‐dimensional detector that records a photoelectron image. It is also equipped with a hemispherical analyzer, which allows state‐of‐the‐art spectroscopic performance to be obtained from very small areas. The instrument is unique in that it collects a much larger solid angle than any other instrument in use today, and spatial resolutions of 2 μm and energy resolutions of 0.25 eV have been achieved.
