حساب كثافة الذرات غير المستقرة في محاكاة التفريغ الومضي في التيار المستمر لغاز الكريبتون

Abstract EN

In this paper, we have calculated the metastable atom density in krypton by a fluid model for gas pressure equal to 0.5, 1 and 1.5 Torrs, and the applied voltages were 200, 300 and 340 volts.

The inter-electrodes spacing was equal to 1 cm.

The chemical processes that were considered in this study were radiation, chemo-ionization, stepwise ionization, both ionization and excitation of the ground atom, and de-excitation and elastic collision.

The model was verified experimentally and theoretically.

The maximum values for the metastable atom density that was registered in this study were equal between 0.54 x 108 and 2.47 x 109cm-3.

Consequently, this model can be used to replace mass spectrometry measurements.
