Dynomak
Dynomak is a spheromak fusion reactor concept developed by the University of Washington using U.S. Department of Energy funding.
A dynomak is a spheromak that is started and maintained by magnetic flux injection. It is formed when an alternating current is used to induce a magnetic flux into plasma. An electric alternating current transformer uses the same induction process to create a secondary current. Once formed, the plasma inside a dynomak relaxes into its lowest energy state, while conserving overall flux. This is termed a Taylor state and inside the machine what is formed is a plasma structure named a spheromak. A dynomak is a kind of spheromak that is started and driven by externally induced magnetic fields.
