Current pulse effect on 2-T inductively coupled plasma

Summary form only given, as follows. I describe a non-LTE model that can be useful in studying non-equilibrated situations of rf-ICP under any externally applied transitions with practically matched situation of an rf-current input. The time-dependent model solves the transport equations of mass, momentum and energy equations along with the vector potential form of Maxwell's equations in 2-T (electron and heavy particle temperature) approach using the SIMPLER algorithm. The temperatures thus obtained are used to calculate the particle densities, which are used to calculate the material properties of plasma, at each and every grids of the ICP torch. The particle densities are calculated accounting species up to single ionization Calculations are done for a 2-D, axisymmetric ICP torch that is surrounded by an rf current-carrying coil of 8 turns and 144 mm length The operating argon gas pressure is 1 atmospheric pressure and the pulsating current of the discharge is varied between 150 and 100 A at a duty factor of 67% with 10 ms pulsing on-time.
