講題: Numerical study of plasma-object interaction: Debye-scale Langmuir probe
摘要: The instrument-carrying satellite and sounding rocket missions are designed to take measurements along the trajectory of spacecraft. However, it is well-known that the local plasma will be disturbed in the process of plasma-object interactions, such as spacecraft body and booms, resulting in the influence on the plasma measurements. For the high-resolution plasma density data, the multi-needle Langmuir probe (m-NLP) instrument, which consists of two or more Langmuir probes, is widely used in the in-situ measurement missions. However, we found that the interaction between space plasma and single Debye-scale probe may also affect the measurement of other probes. To clarify this issue, we employ a self-consistent unstructured Particle-In-Cell model for numerical studies. These studies can provide a reference for the data processing and the future design of m-NLP instruments.
