Abstract
The time-dependent global model is employed to examine the temporal behavio r of the electron density and temperature in helicon plasmas. The power abs orption calculated from the solutions of the Maxwell equations is used in s olving the power balance equation and a balance model for the neutral gas i s considered to find its density self-consistently. The numerical results s uccessfully explain neutral gas depletion and the occurrence of two distinc t modes of pulsed helicon discharge, which have been observed experimentall y.
