Abstract:
An actuatable capacitive transducer including a transducer body, a first capacitor including a displaceable electrode and electrically configured as an electrostatic actuator, and a second capacitor including a displaceable electrode and electrically configured as a capacitive displacement sensor, wherein the second capacitor comprises a multi-plate capacitor. The actuatable capacitive transducer further includes a coupling shaft configured to mechanically couple the displaceable electrode of the first capacitor to the displaceable electrode of the second capacitor to form a displaceable electrode unit which is displaceable relative to the transducer body, and an electrically-conductive indenter mechanically coupled to the coupling shaft so as to be displaceable in unison with the displaceable electrode unit. -

The present invention refers to a method that comprises the following steps: Providing an electrically conductive tip with a terminal shelf which has between three and twenty atoms, generating a first ion beam by interacting a gas with the electrically conductive tip, providing an ion optical system, eliminating by the ion optical system some of the ions in the first ion beam to generate a second ion beam comprising ions 70% or more of which are generated via interaction of the gas with one atom of the terminal shelf of the electrically conductive tip, and interacting the second ion beam with an activating gas to promote a chemical reaction at a surface of a sample.
Abstract:
The invention relates to a motorized manipulator for positioning a TEM specimen holder with sub-micron resolution parallel to a y-z plane and rotating the specimen holder in the y-z plane, the manipulator comprising a base (2), and attachment means ( 30 ) for attaching the specimen holder to the manipulator, characterized in that the manipulator further comprises at least three nano-actuators (3 a , 3 b , 3 c ) mounted on the base, each nano-actuator showing a tip (4 a , 4 b , 4 c ), the at least three tips defining the y-z plane, each tip capable of moving with respect to the base in the y-z plane; a platform (5) in contact with the tips of the nano-actuators; and clamping means (6) for pressing the platform against the tips of the nano-actuators; as a result of which the nano-actuators can rotate the platform with respect to the base in the y-z plane and translate the platform parallel to the y-z plane.

Abstract:
The invention relates to an improved method of electron tomography. Electron tomography is a time consuming process, as a large number of images, typically between 50 - 100 images, must be acquired to form one tomogram. The invention teaches a method to shorten the time needed to acquire this amount images much more quickly by tilting the sample continuously, instead of step-by-step. Hereby the time needed to reduce vibrations between steps is eliminated.
Abstract:
The present invention refers to a system, comprising a scanning electron microscope capable of providing an electron beam and a gas field ion source (120) capable of interacting with a gas (182) to generate an ion beam (192). The scanning electron microscope and the gas field ion microscope (100) are positioned so that, during use, both the electron beam and the ion beam can be used to investigate a sample (180). A system according to the present invention also comprises a focused ion beam instrument. The figure published with the abstract only shows the gas field ion microscope (100).
