Neoclassical Transport Studies in Stellarators Using PRETOR Code

Using PRETOR-Ste code a neoclassical transport study has been done for TJ-II, as well as for LHD device. In the first case, previous results that were obtained using Monte Carlo techniques are reproduced and some of the results obtained with PRETOR-Ste are closer to experimental data. The low collisionality regime is also studied in TJ-II showing the possibility of having the electron root for the electric field in the plasma center. In the case of LHD, results are in concordance with experimental data and with previous studies.
