雪崩-流光跃迁的扩散修正
Diffusion correction to the avalanche--to--streamer transition
摘要：
空间电荷主导的流注放电可以从单个电子在自由空间中出现。我们重新调查的Raether-Meek标准，并表明流光出现不仅取决于电离和附着率和间隙长度，但也对电子扩散。出于模拟结果，我们推导出一个明确的定量标准的雪崩到流光过渡的纯非附着气体和空气，假设雪崩出现从一个单一的自由电子，并在一个均匀的字段中演变。
英文摘要：
Space-charge dominated streamer discharges can emerge in free space from single electrons. We reinvestigate the Raether-Meek criterion and show that streamer emergence depends not only on ionization and attachment rates and gap length, but also on electron diffusion. Motivated by simulation results, we derive an explicit quantitative criterion for the avalanche-to-streamer transition both for pure non-attaching gases and for air, under the assumption that the avalanche emerges from a single free electron and evolves in a homogenous field.
