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.

Formation of Hot, Stable, Long-Lived Field-Reversed Configuration Plasmas on the C-2W Device

June 2019 | H. Gota | Nuclear Fusion | Paper

TAE Technologies’ research is devoted to producing high temperature, stable, long-lived field-reversed configuration (FRC) plasmas by neutral-beam injection (NBI) and edge biasing/control.

CAN Laser Driven Liquid-phase Transmutator Monitored Realtime by Fiber Laser

April 12, 2019 | T. Tajima | Paper

We introduce a method of transmutation of spent radioactive nuclei in a liquid molten salt solution with fusion neutrons through a series of energy enhancements from accelerated deuterons via fusion to fission. This method is a part of the partitioning & transmutation (P&T) approach for the disposal of spent nuclear fuel where P&T enables the reduction of duration and volume of the spent nuclear fuel storage.

Direct observation of ion acceleration from a beam-driven wave in a magnetic fusion experiment

March 2019 | R.M. Magee | Nature Physics | Paper

Efficiently heating a magnetically confined plasma to thermonuclear temperatures remains a central issue in fusion energy research. One well-established technique is to inject beams of neutral particles into the plasma, a process known as neutral beam injection.

Development of a three-wave far-infrared laser interferometry and polarimetry diagnostic system for the C-2W field-reversed configuration plasmas

August 2018 | B. Deng | Review of Scientific Instruments | Paper

Great advancements in modern field-reversed configuration (FRC) experiments motivated the development of a 14-chord three-wave far infrared (FIR) laser interferometry and polarimetry diagnostic system, which can provide simultaneous high temporal resolution measurements of density and Faraday rotation profiles with high accuracy.

Collisional merging process of field-reversed configuration plasmas in the FAT-CM device

July 2018 | F. Tanaka (Nihon Univ.) | Plasma and Fusion Research | Paper

In order to investigate the collisional merging process of field-reversed configurations (FRCs), the FAT device has recently been upgraded to FAT-CM, consisting of two field-reversed theta-pinch (FRTP) formation sections and the confinement section.

Internal Magnetic Field Measurements of Translated and Merged Field-Reversed Configuration Plasmas in the FAT-CM Device

August 2018 | H. Gota | Review of Scientific Instruments | Paper

Field-reversed configuration (FRC) Amplification via Translation–Collisional Merging (FAT-CM) experiments have recently commenced to study physics phenomena of colliding and merged FRC plasma states.
