I ran the simulation on a zircon - for a sample I already had an actual wavescan for at 17kV.
It does a very good job, shows the effect of absorption edge, and allows correct background selection - or use of Mb line. Plus when compare to xeno counter spec 4 see difference
Simulation green. Actual wavescan blue
Hi Ben,
I worked a bit on the higher order Bragg reflection code and here is a simulated scan of U ma ROI on PET for a zircon composition (at 25 keV):
I think this looks better.
By the way I also happened to also run a simulation of the Hf La region and here is a teaching opportunity to demonstrate to students why in zircon we prefer the Hf Ma line:
In addition I ran a full spectrometer range simulation on the K-411 glass here (at 15 keV):
and here is an experimental scan from my SX100:
Not too bad I think. Good enough for teaching in the classroom I think.
The cool thing about this improved simulation mode in the latest PFE is that the students learn not only the theory and practice of EPMA without wasting time on the instrument, but also learn the actual software that they will be utilizing, for when they do get on the instrument!
I'll be uploading this improved simulation version tonight.
