๐ Spectroscopy
Silicon drift detectors (SDDs) are X-ray radiation detectors used in x-ray spectrometry (XRF and EDS) and electron microscopy. Their chief characteristics compared with other X-ray detectors are:
- high count rates
- comparatively high energy resolution (e.g. 125 eV for Mn Kฮฑ wavelength)
- Peltier cooling
