41. ASDEX Upgrade is, compared to other international tokamaks, a midsize tokamak experiment. 42. Korea Superconducting Tokamak Advanced Research ), an advanced superconducting tokamak fusion research device. 43. Korea Superconducting Tokamak Advanced Research ), an advanced superconducting tokamak fusion research device. 44. Such machines include particle accelerators and tokamak reactors. 45. The operation of tokamak restarted with a D-shaped vacuum vessel in 1992. 46. However as measurements became more accurate and tokamak plasmas got hotter, discrepancies appeared. 47. However more accurate experimental methods for measuring q profiles in tokamaks were developed later. 48. Tokamaks are doughnut-shaped, metal chambers within which intense magnetic fields are created.49. Prospects for developing tokamaks capable of generating power at a commercial level now seem bleak. 50. Whether a spherical tokamak or another design will be the answer remains to be seen.
