Laser-plasma technology: the future of particle acceleration
2021年1月14日 · Plasma is one of the four fundamental states of matter (the other states being solid, liquid and gas). To create a plasma, a high-power laser is focused on a target, such as a gas (when accelerating electrons) or a fine solid (for protons). The powerful laser beam instantly ionises the atoms when it interacts with the solid or gaseous material.
