SPRITE Annular Backscattered Electron Detectors:
Silicon PhotomultiplieR Imaging Technology for Electrons
Small and Magical
PulseTor has developed a new BSED detector based on our unique SoM technology.
SPRITE detectors use multiple SiPM chips – from 1X1 mm2 to 1X1 cm2 – as the substrate for thin scintillators. A typical SPRITE detector may have four 4X4 mm2 devices around an annulus, to be mounted under the SEM Polepiece in the conventional manner.
The segmentation is illustrated by the set of images below from the A, B and C devices individually, then the image formed by the sum of the three SoMs. It allows the ability to clearly understand the the topogrpahical relationships.

Another way to take advantage of the unique architecture enabled by SoM technology is to use different scintillator materials in the same detector.
