Sekundärpartikel
Sekundärpartikel, also known as secondary particles, are particles produced by the interaction of primary cosmic rays or other high-energy particles with matter. When a primary particle, such as a proton or atomic nucleus from space, collides with atoms in the Earth's atmosphere or in a detector material, it can break apart or transfer energy, generating a shower of new, secondary particles. These secondary particles are typically less energetic than the primary particle but can include a variety of types such as muons, pions, kaons, and electrons. The composition and energy distribution of secondary particles depend on the energy and type of the primary particle, as well as the properties of the material they interact with. Studying secondary particles is crucial in fields like particle physics and astrophysics, as they provide insights into the fundamental nature of matter and the origins of cosmic radiation. They are also a consideration in radiation protection, particularly for astronauts in space or in high-altitude flights where atmospheric shielding is reduced.
