摘要:
Methods and systems for calibrating a transmission electron microscope are disclosed. A fiducial mark on the sample holder is used to identify known reference points so that a current collection area and a through-hole on the sample holder can be located. A plurality of beam current and beam area measurements are taken, and calibration tables are extrapolated from the measurements for a full range of microscope parameters. The calibration tables are then used to determine electron dose of a sample during an experiment at a given configuration.
摘要:
Control system configured for sample tracking in an electron microscope environment registers a movement associated with a region of interest located within an active area of a sample under observation with an electron microscope. The registered movement includes at least one directional constituent. The region of interest is positioned within a field of view of the electron microscope. The control system directs an adjustment of the electron microscope control component to one or more of dynamically center and dynamically focus the view through the electron microscope of the region of interest. The adjustment comprises one or more of a magnitude element and a direction element.

System and method for safely controlling the containment of gas within a manifold system and the delivery of gas to a sample holder for an electron microscope for imaging and analysis.
摘要:
An apparatus and a method for measuring and monitoring the properties of a fluid, for example, pressure, temperature, and chemical properties, within a sample holder for an electron microscope. The apparatus includes at least one fiber optic sensor used for measuring temperature and/or pressure and/or pH positioned in proximity of the sample.
摘要:
A novel sample holder for specimen support devices for insertion in electron microscopes. The novel sample holder of the invention allows for the introduction of gases or liquids to specimens for in situ imaging, as well as electrical contacts for electrochemical or thermal experiments.
摘要:
A heating device having a heating element patterned into a robust MEMs substrate, wherein the heating element is electrically isolated from a fluid reservoir or bulk conductive sample, but close enough in proximity to an imagable window/area having the fluid or sample thereon, such that the sample is heated through conduction. The heating device can be used in a microscope sample holder, e.g., for SEM, TEM, STEM, X-ray synchrotron, scanning probe microscopy, and optical microscopy.
