Re: FW: [XRF] 59.5keV spectrum cleanup

The filter comes at a cost.? Am I reading it correctly that it reduced the input count to %25 of the non-filtered?? Do we need to wait 4x longer for equal counts when this is used as an exciter?? Was all that low energy activity that is filtered out detrimental or beneficial when the button is used to stimulate XRF in the target? I come at this from a different perspective.? I use the Si-PIN with an Am241 exciter to identify minerals.? In my experience the XRF coming from the target is much stronger than the noise introduced by the Am241, which is mounted on a shield and facing away from the detector.? Attached is a scan of xenotime, which shows a large Y component as well as some U and Pb.? I turned on the Am241 reference lines to show that the Np and Au peaks are very small in comparison.? One quickly learns to recognize and ignore them when identifying the important peaks that emanate from the target: Ti, Mn, Fe, Ta, Th, U, Y, Zr, Nb, REEs.
