    Abstract: In an existing specimen cryo holder, a change in the orientation of a specimen would lead to tilting of a dewar together with the specimen and hence to bubbling of a cooling source contained in the dewar. In view of this, a specimen cryo holder, including a mechanism capable of cooling a specimen while keeping the posture of a dewar in a fixed direction even when the specimen is tilted into a direction suitable for processing or observation thereof, is provided. Also provided is a dewar in which a vacuum maintenance mechanism is mounted to an outer vessel so that an inner vessel holding a cooling source therein is vacuum-insulated from the outside air.

    Abstract: 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.

    Abstract: A system and method for transmission electron microscopy is provided. The sample can be examined from multiple directions using an electron beam in a transmission electron microscope. The sample has at least three observation faces that are not parallel to each other with the thickness of the sample orthogonal to each of the observation faces being less than 200 nm. The sample is mounted on a needle that is needle rotatable about more than one axis so the needle can orient at least three of the observation faces to be normal to the electron beam of the electron microscope for observation.

    Abstract: The invention relates to a dual beam apparatus equipped with an ion beam column and an electron beam column having an electrostatic immersion lens. When tilting the sample, the electrostatic immersion field is distorted and the symmetry round the electron optical axis is lost. As a consequence tilting introduces detrimental effects such as traverse chromatic aberration and beam displacement. Also in-column detectors, detecting either secondary electrons or backscattered electrons in the non-tilted position of the sample, will, due to the loss of the symmetry of the immersion field, show a mix of these electrons when tilting the sample.The invention shows how, by biasing the stage with respect to the grounded electrodes closest to the sample, these disadvantages are eliminated, or at least reduced.
