An open question to be answered is the dependence of the biasing effect on the iota (strong rational values) – iota scan. At the moment – no idea how to realize. Scenario with iota-vac variation? It is expected to obtain knowledge of the evolution of core and edge plasma characteristics for modeling | An open question to be answered is the dependence of the biasing effect on the iota (strong rational values) – iota scan.
