One of Jore's key inventions is the anti-contamination diaphragm for an electron beam apparatus. This innovative diaphragm is designed to reduce object contamination by replacing the customary diaphragm with a more effective solution. The anti-contamination diaphragm features a central aperture that aligns with a standard diaphragm aperture, along with a concentric annular aperture. This design allows for the transmission of a non-paraxial hollow beam, which irradiates a ring around the paraxial focus on the object. The conical hollow anti-contamination beam acts as a barrier against contaminating residual gas molecules, particularly hydrocarbon molecules.
