Long Pulse: Tokamak:
Multi-institutional U.S. research teams are advancing the physics and technology basis for long-pulse burning plasma operation via bilateral research on U.S. and international fusion facilities. Research on overseas superconducting tokamaks, conducted onsite and also via fully remote facility operation, leverages progress made in domestic devices and allows the U.S. fusion program to gain the knowledge needed to operate long-duration plasma discharges in future fusion energy devices. When advantageous, these efforts are augmented by research into long-pulse related physics issues on overseas tokamaks and spherical tokamaks with non-superconducting coil systems.
