题 目1: Impurity
behavior in the presence of RMP
摘要:
It’s recognized
that RMP could affect the MHD behaviors, which play important roles in the
transport of heat and particle in tokamak plasma. Besides, RMP may change the
structure of edge magnetic field in tokamak. And the interaction between edge
particles and the wall is one most important factor for the production of the
impurity. Thus, it could be believed that RMP will also affect impurity
transport in tokamak.

题 目2: The effect of injection impurity on
plasma radiation
摘要:
In J-TEXT when
the density is higher than a certain value, the radiation will be enhanced in
high-field side. This phenomenon can be measured distinctions from impurity
radiation diagnostic, such as CIII. We can find that impurity radiation plays
an important role in this process. Especially, the impurity density
distribution and plasma parameters (such as density, temperature) distribution
is different between high-field side and low-field side. When asymmetric
radiation occurs, the temperature is very low (a few eV). The effect of
temperature on the impurity radiation reflected radiation function Lz(Te). The
impurity implantation with different types of radiation will change the
function, thereby affecting the radiation asymmetry. Injected different kinds
of impurity (such Ar, methane) in J-TEXT, we can find that asymmetry radiation
phenomenon is mainly reflected in edge plasma temperature and impurity
transport.
