What is a fusion reactor?
Fusion reaction is the fusion between two light nucleus , obtaining heavier elements and a big amount of energy. This new generation technology allows cleaner energy obtaining than fission. Despite that actually there are no reactors obtaining cost effective fusion energy, a international project called ITER pretends the construction of a fusion reactor to acquire knowledge in this energy. Later step will develop a pre-commercial fusion reactor. In order to obtain fusion reaction between tritium and deuterium ions, the plasma containing those ions has to be heated to more than 100 millions Celsius degrees. For that, radiofrequency and neutrum injection technologies are used. One of the drawbacks of such a high temperature is that, during heating, the plasma expands and tends to contact the walls, loosing heat. To avoid this heat sink, the plasma must not to touch the walls. This is done confining the plasma with high magnetic fields generated by superconducting coils. Once the fusion r
