Sawtooth-triggered limit-cycle oscillations and I-phase in the HL-2A tokamak
نویسندگان
چکیده
Transitions between low (L-mode) and intermediate (I-phase) confinement regimes triggered by sawteeth are investigated by using multiple Langmuir probe arrays in the edge plasmas of the HL-2A tokamak. The I-phase is characterized by limit cycle oscillations (LCOs). Repeated L-I-L transitions induced by sawtooth heat pulses are also observed. The statistical analyses show that the delay time of the L-I transition

NON-LINEAR MHD STUDIES IN TOROIDAL GEOMETRY DISRUPTIVE PHENOMENA IN TOKAMAK PLASMAS. Sawtooth oscillations and related fluid excitations are studied analytically and computationally, and some modifications relevant to high temperature regimes are presented. The role of the ideal kink in the sawtooth crash and a new theory of density limit disruptions are discussed. 1. NONLINEAR MHD STUDIES IN T...
متن کاملObservation of reversed shear Alfvén eigenmodes between sawtooth crashes in the Alcator C-Mod tokamak.
Groups of frequency chirping modes observed between sawtooth crashes in the Alcator C-Mod tokamak are interpreted as reversed shear Alfvén eigenmodes near the q=1 surface. These modes indicate that a reversed shear q profile is generated during the relaxation phase of the sawtooth cycle. Two important parameters, q_{min} and its radial position, are deduced from comparisons of measured density ...
متن کاملControl of sawtooth oscillation dynamics using externally applied stellarator transform
The control of sawtooth oscillations is an active area of tokamak research. Large sawtooth oscillations need to be avoided in ITER, since these large sawteeth couple to neoclassical tearing modes and edge localized modes resulting in serious confinement degradation. Small sawtooth oscillations, however, may be beneficial in preventing impurity and helium ash accumulation in the center of the pl...
متن کاملFast-ion transport in the presence of magnetic reconnection induced by sawtooth oscillations in ASDEX Upgrade
The transport of beam-generated fast ions has been investigated experimentally at the ASDEX Upgrade tokamak in the presence of sawtooth crashes. After sawtooth crashes, phase space resolved fast-ion D-alpha (FIDA) measurements show a significant reduction of the central fast-ion density more than 50% together with an increase at larger radii. The corresponding loss of fast particles, detected b...
متن کاملImproved core transport triggered by off-axis ECRH switch-off on the HL-2A tokamak
The reduced core transport and the internal transport barrier (ITB) are observed after the ECRH is turned off in the HL-2A tokamak plasmas. It is found that the time delay of the central temperature afer ECRH switch-off increases as the ECRH deposition moves from center to edge. After the far off-axis ECRH switch-off (outside q=2 surface), the central temperature transiently increases for sever...
