  • Spatial phase manipulation of charged particle beam
    Patent number: 11062872
    Abstract: A device for locally manipulating a spatial phase distribution of a charged particle wave propagating along a beam axis comprises a support element having a target region for receiving the charged particle wave propagating along the beam axis and a plurality of phase adjusting elements, supported by the support element and located in the target region, for locally adjusting the phase of the charged particle wave when the charged particle wave impinges on the phase adjusting element. The device also comprises a plurality of control lines connected to the plurality of phase adjusting elements for individually controlling each phase adjusting element.
