By the sawtooth oscillation method, the RE diffusion coefficient in radial transport in the IR-T1 plasma is . The... WebAug 1, 1990 · Abstract Nonlinear 3-D simulation of sawtooth oscillations shows that the helically twisted hot spot has a prominent toroidal bulge at the large major radius side, characteristic of a high {epsilon} {beta} {sub p} instability. This bulge drives other m/n islands just outside the mixing radius resulting in a stochastic annular region.
WebMar 1, 1992 · Abstract. The authors present a theory of fast-ion transport and fast-ion plasma heating in tokamaks with sawtooth oscillations. The theory is valid for ions with orbit widths that are small compared with the region in which the oscillations occur. It is shown (a) that a sawtooth crash leads to the ejection from the central plasma region of ...

WebAug 3, 2024 · From a theoretical point of view, it is widely accepted that sawtooth oscillations are triggered by the instability of a resistive internal kink mode with mode numbers n = m = 1 and that the trigger conditions for the onset of this mode may be strongly affected by two-fluid effects such as electron and ion diamagnetism [ 29 – 35 ].
WebA carrier oscillation in the microwave range is stabilized by a sequence of timing pulses produced by a crystal-controlled reference oscillator whose cadence is an aliquot fraction of the nominal carrier frequency. The pulses are used to obtain two phase-representing amplitude samples of the carrier wave from a pair of mutually phase-shifted ... navigator activexWebApr 11, 2024 · Here’s how it works: Figure 1 DAC controlled triangle/sawtooth generator with weird feedback. 555-based oscillators (almost) universally rely on routing feedback from the output (OUT pin or DSC pin) through an RC integrator (passive or active) to input pins THR and TRG.
