Title: Cheolsu Han: Innovator in Particle Beam Technology

Introduction

Cheolsu Han is a prominent inventor based in Suwon-si, South Korea. He has made significant contributions to the field of particle beam technology, holding a total of 4 patents. His work focuses on advancing methods for particle measurement and mass spectrometry.

Latest Patents

Han's latest patents include a particle beam mass spectrometer and a particle measurement method utilizing this technology. The particle beam mass spectrometer is designed to include a particle focusing unit that concentrates a particle beam induced by gas flow. It features an electron gun that forms a charged particle beam by accelerating thermal electrons to ionize the focused particle beam. Additionally, the device incorporates a deflector that deflects the charged particle beam based on the kinetic energy to charge ratio, along with a sensing unit that measures the current induced by the deflected charged particle beam. The deflector is equipped with at least one particle beam separation electrode positioned on opposite sides of the charged particle beam's progress axis before deflection.

Another notable patent involves an ion source and a mass analysis apparatus. This invention includes an anode tube where gas flowing in is ionized and discharged, featuring a slit on its outer circumference. A filament emits thermal electrons toward the slit to ionize the gas, while a diffusion-preventing body is arranged between the filament and the slit to minimize the diffusion of thermal electrons into the anode tube.
