A toroidal apparatus for producing controlled fusion reactions in hot plasma.
- As discussed earlier, full steady-state operation in a tokamak requires that the inductive plasma current is completely replaced by a non-inductive one.
- The most common mechanism for controlling plasma reactions today is called a tokamak, originally designed by the Russian physicist Lee Artsimovich in the late 1950s.
- In the tokamak, two powerful electromagnets create fields that are so powerful that they can hold a hot plasma in place as readily as a person can hold an orange in her hand.
1960s: Russian, from to(roidal'naya) kam(era s) ak(sial'nym magnitnym polem) 'toroidal chamber with axial magnetic field'.
