    Abstract: A skewed chicane eigenmode exchange module (SCEEM) that combines in a single beamline segment the separate functionalities of a skew quad eigenmode exchange module and a magnetic chicane. This module allows the exchange of independent betatron eigenmodes, alters electron beam orbit geometry, and provides longitudinal parameter control with dispersion management in a single beamline segment with stable betatron behavior. It thus reduces the spatial requirements for multiple beam dynamic functions, reduces required component counts and thus reduces costs, and allows the use of more compact accelerator configurations than prior art design methods.

    Abstract: The present embodiments relate to lowering the widening of a radiation beam, for example, using a chamber arranged between a beam output and an object to be irradiated. The chamber is filled with a gas or a gas mixture, the average atomic number of which is smaller than that of air, and the volume expansion of which is changeable. The advantage here is that a widening of a radiation beam caused by multiple scattering is reduced.

    Abstract: A system for reducing aberration effects in a charged particle beam. The system includes a source of charged particles, such as electrons or ions, and various building blocks for operating on the charged particle beam to generate a desired particle beam pattern. These building blocks can include at least one of a uniform magnetic field component and a uniform electrostatic field component arrangeable in different combinations, enabling coefficients of spherical and chromatic aberration to be canceled out thereby providing a charged particle beam having greatly diminished aberration.

    Abstract: Disclosed is an electromagnetic lens polepiece structure for use in an electron microscope comprising an upper polepiece and an opposite lower polepiece, each having a lens bore, wherein the lens bore portion of the upper polepiece protrudes toward the lens bore of the lower polepiece. The protrudant lens bore portion allows the provision of an X-ray conducting bore for the measurement without disturbing the magnetic field of the lens. This makes it possible a smaller lens bore and, consequently, the spherical aberration is reduced and the resolution of the microscope is improved. The protrudant lens bore structure allows the upper polepiece to be divided into two sections so that the bore section can be replaced easily for the measurement of X-rays.

    Abstract: Techniques for adjusting the shape of an ion beam are described. Characteristics of a desired beam shape may be defined. The ion beam generator may include beam shaping elements associated with tunable parameters that can be set in combination with each other. A search space for the possible combinations is defined. A set of exploratory points in the search space are measured and used to interpolate a large number of interpolated points based on a regression model. Interpolated points that are associated with low confidence values may be measured. Based on the measured and interpolated points, clusters of tunable parameter combinations may be identified for evaluation. The clusters are evaluated for stability and sensitivity, and one of the clusters is selected based on the evaluation. The ion beam generator may be configured based on the selected cluster.
