Overview of the physics and engineering design of NSTX upgrade
Description
The National Spherical Torus Experiment Upgrade (NSTX-U) is the name which NSTX, located at PPPL, is known after a major upgrade that began in 2012. The main upgrades made were a larger centerstack to improve the magnetic confinement, an additional neutral beam injector to improve heating and structural enhancements to adapt the coils and vacuum vessel to the new working conditions. NSTX-U was operational for 10 weeks in 2016 but a failure in one poloidal coil forced the device to shut down and undergo a major repair process. It is expected that NSTX-U will resume operations in 2021.
