The code for the carbon impurity from the guard limiter of the lower hybrid wave antenna on EAST tokamak

Impurities in the LHCD protection limiter have always been one of the problems preventing LHCD from improving the heating efficiency. Based on the EAST device, a one-dimensional program for carbon impurity generation in the LHCD limiter is developed. This program is written with Compaq Visual Fortran program. The program mainly includes three parts: the first part is the fast electron flow generated by low hybrid wave; The second part is the change of sheath structure affected by fast electrons; The third part is the thermal response of materials and the physical and chemical sputtering calculation of carbon. Although the program is aimed at carbon materials, it is also suitable for calculating tungsten materials and other impurity ions. The calculation results of this program support the published article [Ou, Xiang, Liu, et al., Plasma Phys. Control. Fusion 60 (2018) 125007].
