An electron imaging apparatusis disclosed, which is configured for an electron transfer along an electron-optical axis OA of an electronemitting sampleto an energy analyzer apparatus, and comprises a sample-side first lens group, an analyzer-side second lens groupand a deflector device, configured to deflect the electronsin an exit plane of the electron imaging apparatusin a deflection direction perpendicular to the electron-optical axis OA. An electron spectrometer apparatus, an electron transfer method and an electron spectrometry method are also described.

The invention relates to a spin detector arrangement for detecting vector components of a predominating spin vector in a particle beam (T) having a predominating spin orientation of the particles. The spin detector arrangement comprises: a spin rotator () having a switchable coil (), wherein the switchable coil () comprises an axial direction and is aligned such that the particle beam (T) passes through the switchable coil () along the axial direction; a deflection device () connected downstream of the spin rotator () and deflecting the path of the particle beam (T) electrostatically by a deflection angle; a spin detector () connected downstream of the deflection device (), allowing the deflection of the vector component of the spin vector predominating in the particle beam (T) perpendicular to the direction of motion of the particle beam (T); and a switching unit () connected to the switchable coil (), allowing switching of the excitation state of the coil ().

A positioning device provides the capability of moving an object in both a linear and a rotational direction. The positioning device includes a first piezo stack with plural piezo plates that are capable of movement in orthogonal directions with respect to each other. The positioning device further includes a second piezo stack with plural piezo plates that are capable of movement in orthogonal directions with respect to each other. The positioning device also includes a first bearing that is disposed against the first piezo stack. The positioning device further includes a second bearing that is disposed against the second piezo stack. The positioning device also includes a spring element and a fifth bearing that is disposed against the spring element. The first through fifth bearings are disposed around and against the object to be positioned, to provide for positioning of the object in at least one of a linear direction and a rotational direction.
