    Abstract: The present invention relates to a method for determining at least one parameter related to charged particles emitted from a particle emitting sample. The method comprises guiding a beam of charged particles into an entrance of a measurement region by means of a lens system, and detecting positions of the particles indicative of said at least one parameter within the measurement region. Furthermore, the method comprises deflecting the particle beam at least twice in the same coordinate direction before entrance of the particle beam into the measurement region. Thereby, both the position and the direction of the particle beam at the entrance of the measurement region can be controlled in a way that to some extent eliminates the need for physical manipulation of the sample. This in turn allows the sample to be efficiently cooled such that the energy resolution in energy measurements can be improved.

    Abstract: One embodiment relates to a dual Wien-filter monochromator. A first Wien filter focuses an electron beam in a first plane while leaving the electron beam to be parallel in a second plane. A slit opening allows electrons of the electron beam having an energy within an energy range to pass through while blocking electrons of the electron beam having an energy outside the energy range. A second Wien filter focuses the electron beam to become parallel in the first plane while leaving the electron beam to be parallel in the second plane. Other embodiments, aspects and features are also disclosed.
