... scanning electron microscope chamber including the lithium-drifted EDS detector, silicon drift detector (SDD), and wavelength dispersive X-ray detector. The article then provides information on qualitative and quantitative X-ray analysis programs followed by a discussion on EDS elemental mapping. The...

... beam is analyzed electronically, photon by photon, as illustrated in Fig. 5 . The x-ray beam is directed into a semiconductor device (a lithium-drifted silicon crystal). As each x-ray photon enters the detector crystal, it creates numerous electron-hole pairs as it expends its energy interacting with...

... accelerated ions then travel over a drift path to the detector. The lighter ions fly with a higher velocity and arrive at the detector before the heavier ions. Measuring the flight time for each ion allows the determination of its mass. Measuring the ion count helps in the quantification. The combination...
