论文摘要
我们根据类似于电动力保罗陷阱的原理来报告通过静电光学元件对带电颗粒光束进行指导和操纵。我们使用在平面底物上制造的数百个电极并提供静电电压，以创造出运动中带电颗粒的浮动电势潜力。电势的形状和强度可以通过电极的布局和施加的电压来本地量身定制，从而可以控制精确设计的有效电位内带电颗粒梁的控制。我们证明了电子和离子的指导，以提供大量能量（从20至5000 eV）和质量（5E-4到131个原子质量单位）以及电子束分裂作为更复杂的光束操纵的概念验证。可以同时将带电粒子与不同质量的限制，以及在KEV政权中具有能量的电子的指导，并创建高度可定制的潜在景观，这对于常规的电动力保罗陷阱而言，这都是难以实现的。
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.
