31. Research has questioned whether spherical tokamaks are a route to lower cost reactors. 32. Schematically, the RFX-Mod machine is similar to a tokamak system. 33. Its configuration is believed to control plasma turbulence more efficiently than does a tokamak . 34. The group constructed the first tokamaks , the most successful being T-4. 35. Neutral beams are known to drive current in Tokamaks by directly injecting charged particles. 36. The START team began the "'Mega Ampere Spherical Tokamak "' 37. The result was a " veritable stampede " of tokamak construction around the world. 38. The spherical tokamak ( ST ) is an offshoot of the conventional tokamak design. 39. The spherical tokamak ( ST ) is an offshoot of the conventional tokamak design. 40. ASDEX Upgrade is, compared to other international tokamaks , a midsize tokamak experiment.
