Parallel detection electron spectrometer using quadrupole lenses
OL Krivanek, CC Ahn, RB Keeney - Ultramicroscopy, 1987 - Elsevier
The design and performance of a parallel detection electron energy loss spectrometer
utilizing several new design elements are described. The system uses three electromagnetic
quadrupole lenses to transform the electron energy spectrum produced by a single magnetic
sector spectrometer into a magnified spectrum suitable for parallel detection, and detects the
spectrum with a single-crystal YAG scintillator, which is fiber-optically coupled to either a 512-
channel or a 1024-channel photodiode detector. The photodiode is interfaced to a computer …
