Abstract

Abstract:

In view of the characteristics of high frequency pulse discharge in saline solution, a pin-needle reactor structure is designed to study the discharge characteristics of pin-needle discharge under pulse voltage. The different electrical characteristics and experimental characteristics are tested and analyzed, and the relationship between impedance and voltage amplitude from no discharge to discharge is measured. It is proved that the change of steam layer can affect discharge. In the plasma emission spectrum of discharge, the characteristic emission band of OH free radical in the band of 306~312 nm affects the biological tissue excision. The finite element multi-physics model of the discharge is established. The results show that the thickness of the vapor layer is about 100 μm and the electron density of the plasma is about 10¹⁶ cm^-3.

Key words: positive pulse, voltage characteristics, current characteristics, plasma spectrum, spectral fitting, electron density, finite element multi-physical field model, plasma discharge
