The process begins with the absorption of X-ray photons by atoms in the material, leading to the ejection of photoelectrons. By analyzing the energy spectrum of these photoelectrons, information about ...

EDS works by focusing an electron beam onto the sample, which causes the sample to emit X-rays. Each element emits X-rays at unique energy levels, allowing for the identification and quantification of ...

The intense, brief pulses of X-rays from upcoming free-electron lasers will greatly extend X-ray microscopy to the femtosecond time domain and to interatomic length scales. From recent experiments ...

Energy Dispersive X-Ray Spectroscopy (EDS) is a microanalysis method used in addition to scanning electron microscopy (SEM). EDS provides chemical information by detecting x-rays released from a ...

With free-electron lasers, such as the one that will soon be operating at the Stanford Linear Accelerator Center, X-ray microscopy will eventually allow us to image dynamics of molecules on the ...

The Helsinki Center for X-ray Spectroscopy is a unique research and education infrastructure serving users from both academia and industry in their leading-edge research, development and innovation.

It is similar to NMR spectroscopy, but instead of exciting the spins of atomic nuclei, EPR excites the electron spins of unpaired electrons. This technique has a wide range of applications, ...
