Self aligning electron beam gun having enhanced thermal and mechanical stability

Patent Scarpetti, Jr., Raymond D. (Livermore, CA); Parkison, Clarence D [Livermore, CA]; Switzer, Vernon A [Livermore, CA]; ...

A compact, high power electron gun having enhanced thermal and mechanical stability which incorporates a mechanically coupled, self aligning structure for the anode and cathode. The enhanced stability, and reduced need for realignment of the cathode to the anode and downstream optics during operation are achieved by use of a common support structure for the cathode and anode which requires no adjustment screws or spacers. The electron gun of the present invention also incorporates a modular design for the cathode, in which the electron emitter, its support structure, and the hardware required to attach the emitter assembly to the restmore »« less

Analytical scanning evanescent microwave microscope and control stage

Patent Xiang, Xiao-Dong [Danville, CA]; Gao, Chen [Anhui, CN]; Duewer, Fred [Albany, CA]; ...

A scanning evanescent microwave microscope (SEMM) that uses near-field evanescent electromagnetic waves to probe sample properties is disclosed. The SEMM is capable of high resolution imaging and quantitative measurements of the electrical properties of the sample. The SEMM has the ability to map dielectric constant, loss tangent, conductivity, electrical impedance, and other electrical parameters of materials. Such properties are then used to provide distance control over a wide range, from to microns to nanometers, over dielectric and conductive samples for a scanned evanescent microwave probe, which enable quantitative non-contact and submicron spatial resolution topographic and electrical impedance profiling of dielectric,more »« less

Sparse sampling and reconstruction for electron and scanning probe microscope imaging

Patent Anderson, Hyrum; Helms, Jovana; Wheeler, Jason W.; ...

Systems and methods for conducting electron or scanning probe microscopy are provided herein. In a general embodiment, the systems and methods for conducting electron or scanning probe microscopy with an undersampled data set include: driving an electron beam or probe to scan across a sample and visit a subset of pixel locations of the sample that are randomly or pseudo-randomly designated; determining actual pixel locations on the sample that are visited by the electron beam or probe; and processing data collected by detectors from the visits of the electron beam or probe at the actual pixel locations and recovering amore » reconstructed image of the sample.« less
