Application of break-in-slope method in calculating HL-2A ECRH power deposition

Abstract

Abstract:

The basic theory of break-in-slope method in calculating the profile of auxiliary heating power deposition is presented. Using this method, the profile of ECRH power deposition is carried out by analyzing electron temperature and density at the time of ECRH injection on HL-2A for the first time. The applicability of this method is proved.

Key words: Break-in-slope, ECRH, Auxiliary heating, Data analyze, Absorption profile
