Description: The sun creates a lot of energy by hydrogen fusion. Scientists are investigating fusion, building our own ‘sun on earth’, as a sustainable energy source on earth. A lot of energy is released when hydrogen isotopes fuse together into helium and neutrons. One of the key problems is that these high energy neutrons can damage the crystal structure of the surrounding tungsten wall. This can create vacancies in the metal lattice, which trap hydrogen atoms. Trapped hydrogen cannot fuse to release e
