and Training
Dr. Ed Stech ( Department of Physics ) / Week of September
13th, 2010
While PIXE can provide valuable data across
academic disciplines, it does occupy both physical and human resources
in the NSL. X-Ray Fluorescence (XRF) is a complimentary technique which
uses the characteristic x-rays to determine the elemental composition
of samples in a non-destructive way without requiring an accelerator.
After consultations with representatives from EDAX Inc., we have arranged
for an ORBIS micro xrf system to be in the NSL for a week in September.
During this time, EDAX will provide training on the operation of the device
and time to do some test experiments in collaboration with faculty members
in the Department of Anthropology. The ORBIS system is a fully automated
desktop system which allows users to create 2-D maps of the elemental
distribution of samples as large as 270 mm x 270 mm x 100mm with a 30um
beam size. The automated scanning ability coupled with the available analysis
routines will make this an ideal device for multidisciplinary undergraduate
research projects as well as a valuable tool for investigation of targets
and other materials which will assist all NSL users. |
