Description

technical field [0001] The invention belongs to the technical field of physical experiments, and in particular relates to a high-voltage high-charge state ion physics experiment device. Background technique [0002] Highly charged ions widely exist in nature, and the collision between ions and atoms and molecules is one of the main microscopic processes of material interaction in nature. For example, highly charged ions in the solar wind blow to the earth and interact with the atmosphere at the north and south poles to form auroras. The plasmas of magnetic confinement fusion and inertial confinement fusion that humans are developing also have collision processes between highly charged ions and atoms and molecules. Studying the interaction process between highly charged ions and atoms and molecules in the laboratory will help to understand natural phenomena and help better control fusion plasma. At the same time, the study of these collision processes is also an important wa...

Problems solved by technology

It is not easy to obtain high-charged ions with a certain energy in the laboratory. In the early days, they could only be obtained through expensive large-scale accelerators, and the energy is much higher than that of high-charged ions in nature.
