- Abstract summary: We report guiding and manipulation of charged particle beams by means of electrostatic optics.
We use hundreds of electrodes fabricated on planar substrates to create a ponderomotive potential for charged particles in motion.
Shape and strength of the potential can be tailored by the electrodes' layout and the applied voltages.

- Abstract: We report guiding and manipulation of charged particle beams by means of
electrostatic optics based on a principle similar to the electrodynamic Paul
trap. We use hundreds of electrodes fabricated on planar substrates and
supplied with static voltages to create a ponderomotive potential for charged
particles in motion. Shape and strength of the potential can be locally
tailored by the electrodes' layout and the applied voltages, enabling the
control of charged particle beams within precisely engineered effective
potentials. We demonstrate guiding of electrons and ions for a large range of
energies (from 20 to 5000 eV) and masses (5E-4 to 131 atomic mass units) as
well as electron beam splitting as a proof-of-concept for more complex beam
manipulation. Simultaneous confinement of charged particles with different
masses is possible, as well as guiding of electrons with energies in the keV
regime, and the creation of highly customizable potential landscapes, which is
all hard to impossible with conventional electrodynamic Paul traps.

Controlling free-electron momentum states is of high interest in electron microscopy to achieve momentum and energy resolved probing and manipulation of physical systems.
Here, we demonstrate both longitudinal and transverse phase control of a slow electron wavepacket by extending the Kapitza-Dirac effect to spatially-structured pulsed laser beams.
The interaction reveals the formation of distinct electron transverse momentum orders, each demonstrating a comb-like electron energy spectrum.

Most demanding application for a large-scale quantum computer will require ordered arrays.
By configuring an electronic-grade diamond substrate with a biased surface graphene electrode connected to charge-sensitive electronics, it is possible to demonstrate single ion implantation for ions stopping between 30 and 130nm deep from a typical ion source.
This allows the construction of ordered arrays of single atoms with associated colour centres that paves the way for the fabrication of deterministic colour center networks in a monolithic device.
