Ⅰ. INTRODUCTIONAn ergodic magnetic field has been used to control thermal and particle fluxes and edge interactions in TEXT. A set of saddle coils outside the vacuum vessel pro-
Ⅰ. INTRODUCTION Generally, it has been accepted that the ballooning instabilities are the key barriers to the high-beta economical reactor. So we have to seek for an external
Since the method of additional gas puffing during discharges was used for raising the plasma density in Alcator in 1975, a number of devices have been operated in this manner with considerable success. In this report ...
I. INTRODUCTION Recent investigation shows that high-β plasma can be produced in tokamak devi-ces by means of the so-called flux-conserving heating. Though a series of 2-D numerical code have been applied to the stud...
If we neglect the changes of plasma current Ip, poloidal pressure ratio βp, internal inductance ι1 and cross-section radius αp, and only consider the first order of magnitude of the toroidal effect (α/R), we can...
Ⅰ. INTRODUCTIONIt has been proposed and carried out to modulate plasma current in tokamak device with an AC-component. Its purpose was either to measure minor radius of plasma and conductivity distribution, or to car...
It is of great importance for the analysis of stability and transport processes to get the equilibrium configuration of a tokamak plasma with nonuniform current profile.The Grad-Shafranov equation which governs the ax...
Ⅰ. EXPERIMENTAL FACILITIES The machine CT-6B is a shell-less Tokamak. Its major parameters are: radius, R_o=45 cm; the radius of the vacuum chamber, 15 cm; the radius of the Mo limiter, 13 cm; the time constant for v...
Ⅰ. INTRODUCTION LHF heating is one of the possible important methods of auxiliary heating of large Tokamaks. Brambilla’s theory on the self-consistent fields of Grill has been used in the design of the Grill structu...
