In the last year, ECRH system has been built in the HL-2A and the testing of gyrotron is also finished. In the project testing, one of the problems is current-peak occurring in the anode circuit of gyrotron. The curre...
This paper introduces the design of the TZ-2 high voltage modulator for electron cyclotron resonance heating (ECRH) on HL-2A tokamak. The high voltage power supplies (HVPS) for the cyclotron have to operate advant...

Though most of the studies on toroidally axi-symmetric equilibria are based on the scalar pressure assumption that leads to the usual Grad-Shafranov equation, the realistic plasma is generally more complicated and pla...
In this paper we shall consider the effect of compressibility on the RT instability in Z-pinch implosions, importance is the comparing growth rates of the RT instability for two systems of the compressible and incompr...

The effects of trapped electrons on off-axis lower hybrid current drive (LHCD) in tokamaks are studied. The influence of the resonance regime on the current drive efficiency as well as the influence of trapped parti...
In this work, the numerical simulation is employed for HL-2A equipment modification project HL-2M. The design of zero field and evolution of plasma configuration in start-up phase and single null divertor equilibrium ...
The magnetic induction and its ripple due to reconstructive toroidal coils are calculated. The field ripple is so small that the influence of ripple can be omitted for the plasma discharge.
1 Introduction Interaction of radio-frequency wave with plasma in magnetic confinement devices has been a very important discipline of plasma physics. To approach more realistic description of wave-plasma interaction...
