Abstract

We have investigated the use of a Timepix detector as a method for increasing the realisable temporal resolution of a conventional 200keV transmission electron microscope (TEM). Evaluation of both single and integral mode image exposures was performed. Single exposure mode images showed that the available electron beam current became the limiting factor for timescales < 100 mu s. Analysis of integral mode images showed that exposures times down to 500 ns were possible but that increases in image intensity and noise occurred. The performance data obtained represents a significant performance improvement on current TEM CCD imaging detectors.
