Radial distributions of the plasma parameters are obtained. Mercury lines with wavelength of 435.8 nm and 365 nm are measured to testify the model. Based on the model, the population of resonance state 63p1 of mercury in dependence on the argon pressure and driving frequency is calculated. It is shown that the population of 63p1 of mercury is larger when the argon pressure is between 26.6 Pa and 53.2 Pa. Meanwhile the driving frequency has little influence on the population of 63P1.展开更多

The physical configuration is similar to the OSRAM/ENDURA 70 W lamp. A Maxwellian energy distribution is assumed. Two dimensional behaviors of the most important plasma parameters such as the electron density, the electron temperature and the most important mercury states are discussed. Results are in good agreement with former studies and the general understanding in this area. Also, the influence of the argon pressure is studied. Based on the simulation, the population of the main resonance state, Hg (63p1) depends on the argon pressure and the optimized value is about 300 mTorr.展开更多
