Cross-separatrix simulations of turbulent transport in the field-reversed configuration

June 2019 | C.K. Lau | Nuclear Fusion | Paper

Recent local simulations of the field-reversed configuration (FRC) have reported drift-wave stability in the core and instability in the scrape-off layer (SOL). However, experimental measurements indicate the existence of fluctuations in both FRC core and SOL, with much lower amplitude fluctuations measured in the core.

Fusion reactivity of the pB11 plasma revisited

June 2019 | S.V. Putvinski | Nuclear Fusion | Paper

Fusion reactivity for the pB11 fuel has been reassessed for magnetic confinement devices. This study is based on two factors: new measurements of the fusion reaction cross-sections and an accounting of the kinetic effects that lead to the increase of the number of protons at higher energies (with respect to a pure Maxwellian).

Collisional Merging of a Field-Reversed Configuration in the FAT-CM Device

June 2019 | T. Asai | Nuclear Fusion | Paper

Collisional merging formation of field-reversed configurations (FRCs) at super Alfvénic velocity have been successfully initiated in the FAT-CM device at Nihon University. It is experimentally evidenced that the quiescent FRC profile is formed in a self-organizational manner after distructive disturbances by the super Alfvénic collision of two translated magnetized plasmoids.
