Title: Kenji Tsuda: Innovator in Energy Filtering Technology

Introduction

Kenji Tsuda is a prominent inventor based in Hiroshima, Japan. He has made significant contributions to the field of energy filtering technology, holding a total of 5 patents. His innovative work has advanced the capabilities of electron microscopy and energy dispersion techniques.

Latest Patents

One of Tsuda's latest patents is the "Energy Filter," which is an omega energy filter designed to enhance energy dispersion while eliminating second-order aberrations. This filter is mirror-symmetric with respect to the center plane C. The process involves a beam entering a first nonuniform magnetic field produced by a first magnet, followed by a second nonuniform magnetic field region created by a second magnet. The trajectory of the beam is then curved by the field from the second magnet before it enters a third magnetic field region produced by the first magnet, ultimately reaching an exit slit.

Another notable patent is the "Imaging Energy Filter Equipped with Distortion Corrector." This invention integrates an energy filter within an electron microscope and features a spectrometer that utilizes magnets to generate magnetic fields. The spectrometer includes coils for exciting the magnets and potentiometers with variable resistors connected in parallel. The variable resistors are adjusted to control the current ratios flowing into the coils of shunting circuits.
