A unique manipulator for a channel electron multiplier array (CEMA) is described. It allows for easy installation into the viewing chamber of a transmission electron microscope. This device, through a series of motions, positions the CEMA normal to the electron beam, thus amplifying the electron flux while preserving its image. This increase in image brightness permits operation of the microscope with a greatly reduced flux of electrons passing through the sample, thereby decreasing radiation damage while simultaneously extending the time available for examination of the specimen. The manipulator can then move the CEMA to a remote area of the chamber, thus returning the microscope to its normal operating mode.
