    Abstract

    Full penetration of RF electric fields into magnetized plasmas is expected in order to realize the Lissajous helicon plasma accelerator (LHPA). We study the electric field penetration in bulk plasma in one-dimensional electrostatic approximation using two analytical models: the matrix sheath model and the vacuum gap model. An identical formula for the electric field is obtained from the models. The formula is benchmarked by particlein-cell (PIC) simulations. The full penetration of the electric field is realized when the relation (q ≪ 0:01) is satisfied, where q is the measure of the degree of the shielding effect due to plasma density and electron magnetization.
