Penggunaan Pemodelan Sumber Plasma Helium Pada Keadaan Setimbang Untuk Aplikasi Plak Gigi

Abstract

Helium plasma source modelling was performed in order to obtain species density at balanced conditions under pressure of 1 atm. The software used in this modelling is matrix laboratory software (MATLAB). The equation used is a continuity equation that depends on the position and parameters of Arrhenius. Plasma temperatures used were 0.1 eV, 0.2 eV, 0.3 eV, and 0.5 eV. Species involved in a plasma consist of electrons, He, He + , He 2 + , He *, and He 2 * . The modelling results showed that the density value of He species increases as temperature increases. It is noted that the obtained the density of He (n He ) when reaching a balanced condition at the temperature of T = 0.
