METHOD OF IMAGING A SAMPLE USING AN ELECTRON MICROSCOPE
The invention relates to a method of imaging a sample, said sample mounted on a sample holder in an electron microscope, the electron microscope comprising an electron source for generating a beam of energetic electrons along an optical axis and optical elements for focusing and deflecting the beam so as to irradiate the sample with a beam of electrons. The sample holder is capable of positioning and tilting the sample with respect to the electron beam. The method comprises the step of acquiring a tilt series of images by irradiating the sample with the beam of electrons, and concurrently changing a position of the sample during acquisition of the images, so that each image is acquired at an associated unique tilt angle and an associated unique position.
Method of performing electron diffraction pattern analysis upon a sample
A method is provided for performing electron diffraction pattern analysis upon a sample in a vacuum chamber of a microscope. Firstly a sample is isolated from part of a specimen using a focused particle beam. A manipulator end effector is then attached to the sample so as to effect a predetermined orientation between the end effector and the sample. With the sample detached, the manipulator end effector is rotated about a rotation axis to bring the sample into a predetermined geometry with respect to an electron beam and diffraction pattern imaging apparatus so as to enable an electron diffraction pattern to be obtained from the sample while the sample is still fixed to the manipulator end effector. An electron beam is caused to impinge upon the sample attached to the manipulator end effector so as to obtain an electron diffraction pattern.
