the code for the impurity sputtering from theguard limiter of the lower hybrid wave antenna in a tokamak

This program is written by compaq Visual Fortan, which is used to calculate the impurity sputtering considering the existence of high-energy electrons in the sheath structure. By running the program, the concentration and energy of high-energy electrons can be adjusted to obtain the carbon physical sputtering and chemical sputtering rates under different conditions.
