A simulation code to estimate / deduce local toroidal rotation profiles in TJ-II plasmas from chord-integrated measurements

A local model capable of reconstructing the cord-average emission of spectral lines in the TJII stellarator has been developed for inferring local parameters. The procedure was implemented on a numerical code, that starting from given analytical profiles of local emissivity, ion temperature and toroidal rotation, simulates the cord-average emission spectra along a selected line of sight. Additionally, the code is able to separate the toroidal and poloidal velocity contribution taking into account the TJ-II magnetic topology. (Author)
