Tokamak start-up with electron-cyclotron heating
Experiments are described in which the start-up voltage in a tokamak is reduced by about a factor of two by the use of a modest amount of electron cyclotron resonance heating power for pre-ionization. The solution of the zero-dimensional start-up equations indicates that the effect is due to the high initial density which increases the rate at which the conductivity increases in the neutral-dom...
متن کاملDesign Study of a Tokamak Power Reactor with an Electron Cyclotron Resonance Heating System
A detailed design is presented of a tokamak power reactor with an electron cyclotron resonance heating system. Major research topics include: physics constraints imposed on the design of a reactor by the ECR wave absorption conditions; design of the high frequency (200 GHz) gyrotrons needed for plasma heating; the gyrotron power and magnet systems; a microwave transmission system in oversize wa...
متن کاملDesign and Research of Electron Cyclotron Resonance Heating and Current Dive System on HL-2M Tokamak
A research has been conducted to develop an 8MW electron cyclotron resonance heating and current drive (ECRH/ECCD) system on HL-2M tokamak. The ECRH system compromise eight 1MW gyrotrons, eight evacuated transmission lines and three launchers. The main purpose of the ECRH system was to suppress the neo-classical tearing modes and control the plasma profile. This paper presents an overview of th...
متن کاملPfc/ja-83-13 Parametric Phenomena in Electron Cyclotron Resonance Heating of Tokamak Plasmas
A theoretical study of parametric processes near the electron cyclotron resonance region in tokamak plasmas is presented. Parametric dispersion relations, including finite wave length of the driver pump, of principal and harmonic parametric excitations, are given. The problem of primary and secondary decays including their temporal and spatial growth rates is studied. In the nonlinear phase of ...
متن کاملBernstein rays in a Tokamak plasma in the electron - cyclotron heating conditions
TECHNOLOGICAL advances in the construction of high-frequency tubes (gyrotrons) (ALIKAEV et al., 1978; .TORY, 1978) have produced a sustained interest in the possibility of using microwave energy in the electron-cyciotron frequency range (ECF) o = ace, as a promising additional heating scheme for Tokamak plasmas. Nearly all proposed experiments, which will become operative in the next two years ...
