Web6 Silicon Drift Detectors Explained 2.2 How the EDS detector works The EDS detector converts the energy of each individual X-ray into a voltage signal of proportional size. This is achieved through a three stage process. Firstly the X-ray is converted into a charge by the ionization of atoms in the semiconductor crystal. WebEDX material analysis: how X-ray detection works. Unlike BSE, SE and TE, X-rays are electromagnetic radiation, just like light, and consist of photons.To detect them, the latest systems use the so-called silicon-drift detectors (SDDs).These are superior to the conventional Si(Li) detectors due to higher count rates, better resolution, and faster …
