- Many studies have been reported on the simulation of impurity transport phenomena in the Tokamak fusion plasma using the MIST code (1,2,3). The MIST code is to solve the multi-ionization state impurity transport equations by assuming that the transport fluxes of different ionization states are known. In most simulations, the transport fluxes of impurities are usually expressed in terms of diffusion coefficient and convective velocities. By considering the inverse'' problem (vs.MIST), the basic idea of this research is to solve the one dimensional (ONE-D, with cylindrical geometry) impurity transport equations to determine the transport coefficients from the experimental impurity density evolution data. We have developed a computer code which is labelled as DASH'' to solve this problem. The alpha particle transport coefficients can be obtained and inter-corrected by using the MIST and this DASH code. This code also provides a way to check the simulation results of MIST code.
