Fast access to neutral injection heating profiles in W7AS
Description
A fast code was developed to estimate the heating power profiles of the neutral injection system for diagnosed shots of W7AS. This code, named NIPOR, uses a number of data sets of the local power deposition of neutral beams and analytical fits of the total heating efficiency for each source. These data were obtained by previous runs of FAFNER1, a Monte Carlo code for simulating the NI heating on W7AS. The main input parameters needed for this estimation are the electron density ne(r), electron temperature Te(r), toroidal magnetic field Bo and the identifiers of the active NI-sources at the corresponding time tc. These data are routinely read from the ORACLE data set. (orig.)
