The DIII-D reactor at General Atomics in San Diego is a respectably large tokamak fusion reactor with ohmic heating, ion-cyclotron and electron-cyclotron resonance heating and neutral beam injection. Typical experimental parameter space achieves a lawson criterion confinement better than most other fusion reactors and on par with the now decomissioned TFTR but not as good as JT-60 or JET, not to mention ITER.
