Magnetic Electron Lens for TEM
Type: Undergraduate project (3 months)
Overview
Designed and manufactured a magnetic electron lens for a Transmission Electron Microscope (TEM). The lens focuses electron beams to produce atomic-scale images of specimens.
What I Did
- Designed the magnetic circuit (pole pieces, coil geometry, yoke) to produce a precisely shaped magnetic field
- Optimized the lens geometry for minimal spherical and chromatic aberration
- Oversaw manufacturing to the tight tolerances required for TEM optics
The project gave me hands-on experience with electromagnetic design, precision manufacturing, and the physics of charged particle optics.
