Working Principle
In the field of electron and ion beam technology, the use of well-focused particle beams is of paramount importance. D.I.S Germany is proud to provide highly advanced products in the field of charged particle beam optics. These products are designed to be customizable, ensuring a perfect fit for our customers’ facilities.
Electrostatic lenses are devices that focus charged particle beams. They work by applying different voltages to electrodes, creating a spatially distributed electric potential that deflects the particles and influences the beam opening angle. In a classical einzel lens the outer electrodes are at the same potential not changing the kinetic particle energy.
In contrast, a transition lens is an electrostatic lens whose outer electrodes carry different voltages, causing a change in the particle kinetic energy along the lens. Thus, a transition lens allows the charged particle beam to travel through a potential energy change with optimal control of the beam divergence.
Applications
A transition lens is generally employed to adjust particle energy in set-ups with various beamline potentials along the beam, even under extreme vacuum conditions. This capability enables a range of functions, including beam acceleration or deceleration, energy state adjustment at the start, along or at the end of a beamline, energy matching in extreme vacuum conditions, and guiding charged particle beams through specific potential stages. These functionalities ensure that beamline potential transition segments are optimized for particle transmission and controlled beam divergence.
