AB  - The properties (densities of electrons and metastable argon atoms, effective electron temperature and dust charge) of argon/dust and pure argon pulsed plasmas are studied using a spatially-averaged model. The calculated time-dependencies for the densities of electrons and metastable atoms are compared with the experimental measurements and are found to be in a good qualitative agreement. It is analyzed how the plasma properties depend on the shape of the electron energy probability function (EEPF), the pulsing frequency and the duty cycle for both dust-free and dusty plasma. The analysis reveals that the agreement between theory and experiment is better with Druyvesteyn EEPF than the Maxwellian EEPF. Further, the variation in the pulsing frequency νp differently affects the metastable density nm in a dust-free and in a dusty plasma. For large νp, the metastable density in the dust-free pulsed plasma is larger than in the continuous-wave (CW) discharge, while the opposite is obtained in the presence of dust particles. This difference probably arises because of faster variation in the effective electron temperature in the dusty plasma due to collection of electrons by dust particles. Our calculations also show that dust particles may affect the behavior of electron density in the beginning of the on-period due to an enhancement in electron collection by dust particles.

AB  - A spatially-averaged model for an argon/dust pulsed plasma is developed in this study [1]. We analyze how the plasma properties depend on the shape of the electron energy probability function (EEPF), the pulsing frequency and the duty cycle. In addition, the case of dust-free plasma is considered.  It is found that the results of theory and experiment agree better if the assumed EEPF has a Druyvesteyn shape instead of a Maxwellian one. As an example, we compare electron and metastable atom densities for different plasma states. In particular, the model shows that in the presence of dust and at some pulsing frequencies the electron density decreases rapidly in the very beginning of the on-period. In our opinion, this decrease is due to an enhancement of electron collection by dust particles at the beginning of the on- period. Further, variation in the pulsing frequency differently affects the metastable density in a dust-free and in a dusty plasma. For large pulsing frequencies (≥ 7 kHz), the metastable density in presence of dust is smaller than in the continuous-wave discharge, contrary to the dust-free case. Our model shows that the collection of electrons by dust particles causes the faster variation of the effective electron  temperature leading to the lower metastable density. Using a 1D model we describe the plasma properties during the off-period (afterglow) also. The charge of a dust particle and the forces affecting the dust particle are studied for different neutral gas pressures and dust radii. It is found that at long afterglow times, the electric force affects more essentially the dust particle than the ion drag force. These results on dusty pulsed plasmas are relevant to many applications involving nonstationary plasmas containing impurities such as those for synthesis of novel nanomaterials.
