Thanks M Quack and mfb. Yes, it's an Si(Li) detector. It does seem plausible that it's something to do with thermal leakage noise from the X-ray tube. Mfb - what do you mean? If we consider only bremsstrahlung radiation, then surely the resulting spectral continuum curve (I love using the...

When photons enter the detector unit of the XRF instrument, they are converted to a series of electrical charges until the photon absorption occurs. The charge are moved to the sides of the detector, in turn creating a deltaV that can be amplified. In this process, detector output voltage moves...

Hello, I can't seem to find a comprehensive explanation for this recurring phenomenon on my XRF spectra graphs. It's a high intensity peak that occurs seemingly below the 0 keV energy mark. And it seem to be common to many graphs, yet nowhere seems to say what it actually is, aside from a...

Hello everyone, I have a few questions regarding the principles behind XRF spec, as most of the sources I've consulted either don't go into enough detail and miss bits out (undergrad textbooks), or are simply beyond my current level of understanding (QM papers etc). When, for example, a...
