Examples

some astronomers believe that the solar system was formed by spallation when the sun was a very young star Source: Internet

A low density TPS material might lack the tensile strength to resist spallation if the dynamic pressure is too high. Source: Internet

During spallation (bombardment with high energy protons), a uranium carbide target is heated to several thousand degrees so that radioactive atoms produced in the nuclear reaction are released. Source: Internet

Peak dynamic pressure can also influence the selection of the outermost TPS material if spallation is an issue. Source: Internet

For access to intense neutron sources, researchers must go to a specialist neutron facility that operates a research reactor or a spallation source. Source: Internet

It is formed in minor amounts in cosmic ray spallation nucleosynthesis and may be found uncombined in cosmic dust and meteoroid materials. Source: Internet
