Code for the effect of energetic electrons on the collisionless fusion plasma sheath in ion cyclotron range of frequencies heating

In Tokamak, if low hybrid wave and ion cyclotron wave are used for heating at the same time, high-energy electrons generated by low hybrid wave will affect the RF sheath induced by ion cyclotron wave through magnetic linkage, resulting in enhanced impurity sputtering. To solve this problem, a one-dimensional collisionless RF sheath program containing high-energy electrons is developed. Based on the RF sheath model established by Edelberg and Aydil in 1999, the program adds high-energy electronic components, and is compiled by Compaq Visual Fortran. The structure of RF sheath containing high-energy electronic components changes with time and space. On this basis, the ion energy hitting the material can be calculated (also applicable to multi-component ions), The impurity sputtering is thus calculated. The results of this program support published articles [Ou, An, and Men, Phys. Plasma 26, 123514 (2019);]
