Position Sensitive Detector (PSD)

 

 

Position sensitive detectors (PSD) are proportional counters that use gas ionization and a localized electron-avalance process to amplify the signal from a detected X-ray. Both linear (1-D) and area (2-D) type position sensitive detectors (PSD) are available. Linear position-sensitive detectors use a fine wire to collect intensity over an angular range simultaneously, offering speed advantages up to one hundred times that of a point detector (scintillation and solid-state). These PSDs may be held fixed over a 5 to 10 degree 2-theta range, or scanned like a point detector over a larger range. The speed of this detector is advantageous for high sample throughput, time-resolved studies, weakly diffracting materials, and the detection of minor phases.
