What Challenges are Associated with Beam Alignment?
Despite advances, several challenges persist in beam alignment:
Thermal Drift: Changes in temperature can cause components to expand or contract, leading to misalignment over time. Vibration: External vibrations from the environment can disrupt the alignment, particularly in high-resolution applications. Charging Effects: For electron beams, the charging of non-conductive samples can deflect the beam, complicating alignment. Complexity: The increasing complexity of nanotechnology applications demands higher precision, making alignment more challenging.
