Abstract: |
Tomography is commonly used in tokamaks in order to reconstruct the profile of plasma in a section. This work aims at finding the best placement of the bolometers in DTT (Divertor Tokamak Test) in order to obtain the best possible tomographic reconstructions. The Python package CHERAB is used to perform these synthetic diagnostics. It considers a limit of 96 lines of sight and the limited room available in the tokamak. Different setups were tested and iteratively improved. A statistic was defined to assess the performances of a setup regarding a set of arbitrary emitters. It permits to rank setups between them and determine the best one. Then an analysis was conducted with the best setup on an emitter consisting of the combination of SOLPS-ITER simulation results and core plasma simulation results considering different wavelength ranges which can be observed by bolometers. With a determination of the reconstruction parameter like in experimental conditions, this analysis permits to obtain realistic results of tomography inside DTT. |
