Field reversed configurations

  title={Field reversed configurations},
  author={Michel Tuszewski},
  journal={Nuclear Fusion},
The review is devoted to field reversed configurations and to the related field reversed mirrors; both are compact toroids with little or no toroidal magnetic field. Experimental and theoretical results on the formation, equilibrium, stability and confinement properties of these plasmas are presented. Although they have been known for about three decades, field reversed configurations have been studied intensively only in recent years. This renewed interest is due to the unusual fusion reactor… 

Review of field-reversed configurations

This review addresses field-reversed configurations (FRCs), which are compact-toroidal magnetic systems with little or no toroidal field and very high β (ratio of plasma pressure to magnetic

Stabilization of interchange modes by rotating magnetic fields.

A new method is demonstrated here for the first time, utilizing rotating magnetic fields that are simple to apply and highly effective, and could become a cornerstone for high-beta plasma stability.

Nonlinear stability of field-reversed configurations with self-generated toroidal field

The field-reversed configuration (FRC) is a high-beta compact toroidal plasma confinement scheme in which the external poloidal field is reversed on the geometric axis by azimuthal (toroidal) plasma

Field reversed configurations and spheromaks

The status of controlled nuclear fusion research is reviewed for two major compact toroidal confinement concepts: the field reversed configuration (FRC) and the spheromak. The FRC is an inherently

Field-reversed configurations (FRC) are plasma confinement systems with no toroidal magnets and little toroidal field. The typical plasma shape is sausage-like. FRCs have natural attributes that

Recent Results on Field Reversed Configurations from the Translation, Confinement and Sustainment Experiment

The field-reversed configuration (FRC) offers an attractive alternative approach to magnetically confined fusion because of its extremely high β, simple linear geometry, and natural divertor for

Additional Control Experiments on Field Reversed Configuration Plasma

Plasmas with field reversed configuration (FRC) are confined in open systems and have extremely high beta value of about 100% and they are one of candidates for an attractive reactor. But, in many

Kinetic simulations of the formation and stability of the field-reversed configuration

The Field-Reversed Configuration (FRC) is a high-beta compact toroidal plasma confined primarily by poloidal fields. In the FRC the external field is reversed on axis by the diamagnetic current

Advances in the numerical modeling of field-reversed configurations

The field-reversed configuration (FRC) is a compact torus with little or no toroidal magnetic field. A theoretical understanding of the observed FRC equilibrium and stability properties presents

Dynamic formation of a hot field reversed configuration with improved confinement by supersonic merging of two colliding high-β compact toroids.

A hot stable field-reversed configuration (FRC) has been produced in the C-2 experiment by colliding and merging two high-β plasmoids preformed by the dynamic version of field- reversed θ-pinch technology with significant implications for fusion research and the physics of magnetic reconnection.



The origin of rotation in field-reversed configurations

The stable lifetimes of many field-reversed configuration (FRC) experiments have been observed to be limited by the onset of the m = 2 rotational instability. The origin of the rotation which drives

Suppression of the n=2 rotational instability in field‐reversed configurations

Compact toroid plasmas formed in field‐reversed theta pinches are generally destroyed after 30–50 μsec by a rotating n=2 instability. In the reported experiment, instability is controlled, and the

An analytic solution is obtained for the structure of a prototype reversed field sheath. The configuration is a region of uniform (direct) magnetic field separated from a second region of uniform

Spontaneous development of toroidal magnetic field during formation of field-reversed theta pinch

The formation of an FRC (Field-Reversed Configuration) is considered by using a hybrid simulation model that treats the electrons as a zero-inertia thermal fluid and the ions either kinetically or as

Plasma rotation in reversed-field theta pinches

Field reversed plasmas have been observed to spin up and develop a destructive rotating m=2 instability. While the instability threshold has been reasonably well characterized, the cause of rotation

Plasma stability of a nearly spherical field‐reversed configuration

A nearly spherical field‐reversed configuration (FRC) is created by employing a combination of a double‐cusp bias magnetic field and laser‐produced plasma, and its plasma stability is studied. The

The n = 2 mode rotational instability, which appears on a field-reversed configuration plasma produced by a theta pinch, is stabilized by a helical quadrupole field. The critical strength of the

Experimental evidence is presented which shows that stability for a cylindrical plasma sheet confined by antiparallel magnetic fields is established for times which are longer than theoretically
