Micro-beam XRF localization by a laser beam

Micro-beam XRF localization by a laser beam 1 first-author 1 1 1 1 Shanghai Institute of Nuclear Research, Chinese Academy of Sciences, Shanghai 201800 Shanghai Institute of Nuclear Research, Chinese Academy of Sciences, Shanghai 201800 A new method for micro-beam XRF localization is presented. A laser beam along with an incident X-ray hits on the surface of a sample. The micro region on the sample that reached by X-ray beam can be localized by means of the visible spot of the laser beam. This method is suitable for X-ray microprobes using an X-ray tube or synchrotron radiation as excitation sources. Localization for X-ray micro-beam Laser beam References Rindby A .
