超高速碰撞2024-T4铝靶产生等离子体的朗缪尔双探针诊断(英文)
Double-Langmuir Probe Diagnostics of Plasma Produced by Hypervelocity Impact 2024-T4 Aluminum Target
摘要
Abstract
In some types of plasma,there did not exist an electrode or reference point. The electrode or reference point was needed when applying a bias voltage to a Langmuir probe. To acquire the characteristic parameters of transient plasma generated by hyperveloeity impact,diagnostic system was established. The new electrostatic probe diagnostic system utilizing the double-Langmuir probe was given, in which no voltage and frequency sweep was required. This method can measure electron temperature and electron density as a function of time. This new instrument was based on a double-channel circuit, the current and voltage spectra were obtained from the probe synchronously by a digital oscilloscope. The aim of this work was to apply the double- Langmuir probe diagnostic system to time-dependent plasmas generated by 2024-T4 aluminum projectile hyper- velocity impact 2024-T4 aluminum target.关键词
