Latest Patents
One of Oohashi's latest patents is an electron multiplier unit that includes first and second support members. This invention enables cascade multiplication of electrons through successive emission of secondary electrons in multiple stages in response to the incidence of primary electrons. The design features a first support member with an inlet aperture for primary electrons and a second support member facing the first. The first support member is equipped with a focusing electrode that alters the trajectories of primary electrons to guide them to the inlet aperture. The electron multiplication section comprises at least a first dynode of a box type and a second dynode with a reflection-type secondary electron emission surface. This innovative design ensures that secondary electrons emitted from the first dynode do not directly reach the anode, allowing for efficient electron multiplication.
