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 کاملStudy of Plasma Start-up Initiated by Second Harmonic Electron Cyclotron Resonance Heating on WEGA Experiment
Although both 1 harmonic ordinary mode (O1) and 2 harmonic extra-ordinary mode (X2) have been successfully used to initiate pre-ionization and breakdown in many devices, a complete theoretical model is still missing to explain the success of this method. Moreover, some experimental observations are not completely understood, such as what occurs during the delay time between the turn-on of ECRH ...
متن کاملElectron Cyclotron Heating in the Constance 2 Mirror Experiment* Electron Cyclotron Heating in the Constance 2 Mirror Experiment
Electron cyclotron heating of a highly-ionized plasma in mirror geomctry is investigated. Of primary interest is the experimental diagnosis of the elcctron energy distribution and the comparison of the results of this diagnosis with a two dimensional, time-dependent Fokkcr-Planck simulation. 'Tliese two goals are accomplished in four steps. (1) First, the power balance of the heated and unheate...
متن کاملParametric Decay Instability During High Harmonic Fast Wave Heating Experiments on the TST-2 Spherical Tokamak
A degradation of heating efficiency was observed during high-harmonic fast wave (HHFW) heating of spherical tokamak plasmas when parametric decay instability (PDI) occurred. Suppression of PDI is necessary to make HHFW a reliable heating and current drive tool in high β plasmas. In order to understand PDI, measurements were made using a radially movable electrostatic probe (ion saturation curre...
متن کاملA line-of-sight electron cyclotron emission receiver for electron cyclotron resonance heating feedback control of tearing modes.
An electron cyclotron emission (ECE) receiver inside the electron cyclotron resonance heating (ECRH) transmission line has been brought into operation. The ECE is extracted by placing a quartz plate acting as a Fabry-Perot interferometer under an angle inside the electron cyclotron wave (ECW) beam. ECE measurements are obtained during high power ECRH operation. This demonstrates the successful ...
