Design 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 کاملPower Absorption Calculation for Electron Cyclotron Resonance Heating in H-1 Heliac
Power absorption is calculated for electron cyclotron resonance heating (ECRH) in the H-1 heliac device by using a ray tracing numerical code. The three-dimensional magnetic field structure and the bean shape of flux surfaces are considered. The calculation results show that the second harmonic extraordinary mode heating is effective even at low density if the launching direction is properly ad...
متن کاملIn Ion-cyclotron Resonance Heating
We determine the conditions under which the damping of the fast Alfven wave, used in the heating of tokamak plasmas, can be described by the geometrical optics approximations. Also, for these conditions, we derive an analytical formula which explicitly determines the amount of energy which is damped onto the plasma particles by the fast wave. The conditions for the validity of the geometrical o...
متن کاملCharacteristics of Electron Cyclotron Resonance Heated Tokamak Power Reactors
A set of constraints is derived for the operating characteristics of tokamak power reactors which are bulk heated by electron cyclotron resonance heating (ECRH). Four heating modes are considered: ordinary wave heating at the electron cyclotron frequency, 0, and at the second harmonic frequency, 20, and extraordinary wave heating at 0 and at 20. For ordinary wave heating at 1, which appears to ...
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 ...
