Electron crystallography with the EIGER detector

IUCrJ. 2018 Feb 14;5(Pt 2):190-199. doi: 10.1107/S2052252518000945. eCollection 2018 Mar 1.


Electron crystallography is a discipline that currently attracts much attention as method for inorganic, organic and macromolecular structure solution. EIGER, a direct-detection hybrid pixel detector developed at the Paul Scherrer Institut, Switzerland, has been tested for electron diffraction in a transmission electron microscope. EIGER features a pixel pitch of 75 × 75 µm2, frame rates up to 23 kHz and a dead time between frames as low as 3 µs. Cluster size and modulation transfer functions of the detector at 100, 200 and 300 keV electron energies are reported and the data quality is demonstrated by structure determination of a SAPO-34 zeotype from electron diffraction data.

Keywords: EIGER; SAPO-34; electron crystallography; hybrid pixel detectors.
