GENERATION OF CHARGED PARTICLE VORTEX WAVES |
摘要 |
<p>A device is arranged for imparting an orbital angular momentum to a charged particle wave propagating along an axis in a charged particle beam generating apparatus. The device includes a first conductive element comprising a plurality of angularly spaced electrical conductors arranged around the axis, and a second conductive element. The first and second conductive elements are spaced apart along the direction of the axis, and are adapted for transmitting a charged particle wave propagating along the axis. A connecting means is adapted for supplying an electrical potential to the plurality of angularly spaced electrical conductors for inducing an angular gradient of the phase of the charged particle wave when transmitted along the axis, in which the projection along the axis of the electrical potential varies as a function of an angular position with respect to the axis.</p> |
