Arthur Wehnelt was a German physicist known for his contributions to the field of physics, particularly in the study of electron optics and the development of devices that manipulate electron beams. One of his notable inventions is the Wehnelt cylinder, which is a component used in electron guns to focus and control electron beams. The Wehnelt cylinder is a crucial element in various applications, including electron microscopes and cathode ray tubes, where precise electron beam control is essential for imaging and display technologies.
