Probing warm dense matter using femtosecond X-ray absorption
spectroscopy with a laser-produced betatron source
Intense laser pulses make it possible to create high quality X-Ray radiation sources in a laboratory setting where typically large synchrotron sources are needed.
A research team from France has created such a source for ultrafast X-Ray absorption experiments on the femtosecond timescale. The researchers study what happens in the first few moments when a material is heated with a short, intense laser beam. The setup includes an X-Ray spectrometer where the radiation is detected with an in vacuum MTE camera.
