For those who performed XRF experiment at 4W1B since Nov.2012:

Sample in text:

The micro-X-ray fluorescence (μ-XRF) microspectroscopy experiment is performed at 4W1B endstation, Beijing synchrotron Radiation Facility, which runs 2.5GeV electron with current from 150mA to 250mA. The incident X-ray energy is monochromatized by W/B4C Double-Multilayer-Monochromator (DMM) at 15keV and is focused down to 50 μm in diameter by the polycapillary lens. The two-dimensional mapping is acquired by step-mode: the sample is held on a precision motor-driven stage, scanning XX μm stepwise. The Si (Li) solid state detector is used to detect X-ray fluorescence emission lines with live time of XX s. The data reduction and process were performed using PyMCA package [1].

In Acknowledgments

The μ-XRF beam time was granted by 4W1B endstation of Beijing Synchrotron Radiation Facility, Institute of High Energy Physics, Chinese Academy of Sciences. The staff members of 4W1B are acknowledged for their support in measurements and data reduction.
