High-Resolution X-ray Fluorescence Spectrometer
On the left is the enclosure that houses the x-ray tube and a liquid-nitrogen-cooled Si(Li) x-ray detector. The LN2 Dewar can be seen protruding from the top of this enclosure. Samples are placed in the small Pb-lined box in front. Behind that enclosure, just to the left of the computer, are the pulse-processing electronics. The multichannel analyzer is located on a PC card in the computer. The Si(Li) detector achieves a FWHM of 180 eV for the Fe Ka line. Displayed on the monitor is the K x-ray spectrum of Pd.
James Willis, who is the author of the PC software that provides both qualitative and quantitative analysis of the x-ray data, assembled this unique system (Yes, the enclosure is made of plywood!) and has provided it to EarthTech on an extended loan.
With this system we now have on-site non-destructive analytical capabilities (similar to those employed in our investigation of the RIFEX kit) that will significantly enhance our research efforts.
Thank you, Jim!
