Following a request from Ahmed Diallo, I have started the analysis of the Alcator C-Mod discharge 1120815027. The objective if this study is to compute the neoclassical transport at the plasma edge of this discharge and to compare the neoclassical coefficients with some known analytical formulas. After usual several short XGC0 simulations, I was able to reconstruct the anomalous transport coefficients that are needed to match the simulated density profiles with the experimental profiles. There is still some work that is needed to match the temperature profiles. Here is the summary of plasma profiles that are computed so far (case xcmod.a27):
Electron density / Electron and ion temperatures
Toroidal and poloidal velocities
Effective neoclassical diffusivites
Radial electric field and bootstrap current
Here, HH stands for the Hinton-Hazeltine formulas for the bootstrap current and the radial electric field.
These results were discussed with Ahmed and it has been decided that the toroidal and possible poloidal rotation profiles need to be compared with the experimental data from Alcator C-Mod. However, because most of measurements are for impurities, it will be necessary to rerun the XGC0 code with impurities. I will need to update the code either from Devon or somebody else from the CS group.
