Abstract

The translating velocity of a field-reversed configuration plasma is controlled using a pulse mirror field. Numerical calculations are carried out, using a flux-conserving moving mirror coil, to simulate the motion of the plasma subject to the pulse field. The calculations suggest that it is possible to stop the plasma smoothly without reflection under the pulse mirror coil when the strength of the mirror is changed depending on the velocity of the plasma. In the experiment, the pulse field is produced by a current flowing in a one-turn coil installed inside a theta-pinch coil. It is demonstrated that the translating plasma passing under the one-turn coil is reflected and stops depending on the strength of the pulse field. The optimum strength of the field to stop the plasma without reflection is in good agreement with the estimation of the calculations.

Experimental studies of field-reversed configuration translation

Journal Article Rej, D; Armstrong, W; Chrien, R; ... - Phys. Fluids; (United States)

In the FRX-C/T experiment (Proceedings of the 9th Symposium for Engineering Problems of Fusion Research (IEEE, New York, 1981), p. 1751), field-reversed configuration (FRC) plasmas have been formed in, and launched from, a field-reversed theta-pinch source and subsequently trapped in an adjacent confinement region. No destructive instabilities or enhanced losses of poloidal flux, particles, or thermal energy are observed for FRC total trajectories of up to 16 m. The observed translation dynamics agree with two-dimensional magnetohydrodynamic (MHD) simulations. When translated into reduced external magnetic fields, FRC's are observed to accelerate, expand, and cool in partial agreement with adiabatic theory. Themore »« less

Translation experiments of field-reversed configuration plasma

Journal Article Himura, Haruhiko; Okada, Shigefumi; Goto, Seiichi - Fusion Technology

Translation dynamics of field-reversed configuration (FRC) plasmas are studied in the FRC Injection Experiment (FIX) machine. FRC plasmas have been formed in, and launched from, a field-reversed theta-pinch source, and subsequently translated into reduced external magnetic fields. When translated into an adjacent confinement region, incident velocity of the formed FRC exceeds the Alfven velocity. Moreover, the translated FRC cools less than the prediction of an adiabatic theory. The plasma reflects from an external mirror and some of its axial kinetic energy is lost during every reflection. In this reflection process, significant plasma heating is observed in the case where themore »« less

Adiabatic model and design of a translating field reversed configuration

Journal Article Intrator, T; Siemon, R; Sieck, P - Physics of Plasmas

We apply an adiabatic evolution model to predict the behavior of a field reversed configuration (FRC) during decompression and translation, as well as during boundary compression. Semi-empirical scaling laws, which were developed and benchmarked primarily for collisionless FRCs, are expected to remain valid even for the collisional regime of FRX-L experiment. We use this approach to outline the design implications for FRX-L, the high density translated FRC experiment at Los Alamos National Laboratory. A conical theta coil is used to accelerate the FRC to the largest practical velocity so it can enter a mirror bounded compression region, where it mustmore »« less

FRC (field-reversed configuration) translation studies on FRX-C/LSM

Conference Rej, D; Barnes, G; Baron, M; ...

In preparation for upcoming compression-heating experiments, field-reversed configurations (FRCs) have been translated out of the FRX-C/LSM theta-pinch source, and into the 0.4-m-id, 6.7-m-long translation region formerly used on FRX-C/T. Unlike earlier experiments FRCs are generated without magnetic tearing in the larger FRX-C/LSM source (nominal coil id = 0.70 m, length = 2 m); larger, lower-energy-density FRCs are formed: r/sub s/ approx. = 0.17 m, B/sub ext/ approx. = 0.35 T, approx. = 7 /times/ 10/sup 20/m/sup /minus/3/ and T/sub e/ + T/sub i/ approx. = 400 eV. An initial 3-mtorr D/sub 2/ pressure is introduced by either static or puffmore »« less

Field-reversed configuration formation, translation, and confinement studies on the FRX-C/T experiment

Conference Siemon, R; Armstrong, W; Chrien, R; ...

The field-reversed configuration (FRC) is a high ..beta.. (>50%), prolate compact toroid plasma contained primarily by poloidal magnetic fields. FRC plasmas with parameters, anti n = (1-5)x10/sup 15/cm/sup -3/, T/sub i/ = 0.1-0.8 keV, T/sub e/ = 0.1-0.2 keV, R approx. = 7 cm, B = 5-8 kG, lifetimes less than or equal to300 ..mu..s, are studied on the FRX-C/T experiment at Los Alamos. FRX-C/T consists of a 0.5-m-dia, 1.0-m-long field-reversed theta-pinch coil, and a 0.4-m-dia, 5-m-long translation region into which FRC's are launched, translated, and trapped. A 5-20 mtorr pressure D/sub 2/ fill is introduced into the device bymore »« less
