Abstract
An electron detection device for use with an electron microscope defining a sample chamber. The device comprises a housing which in use is mounted to and opens into or forms part of a sample chamber of an electron microscope. A support structure is attached to the detection device housing and is in communication with the sample chamber in use. The support structure supports within it a member from which depends a phosphor scintillator, the member being movable between an extended position in which the phosphor scintillator is close enough to a sample to be struck by electrons and a retracted position. A control system controls movement of the member; and a detector monitors light emitted by the phosphor scintillator in response to electron impact.
