采用粒子模拟方法研究了高压氢气中纳秒脉冲微放电的电子动力学行为。放电由峰值为1.3 kV的10 ns电压脉冲驱动，随后在150 ns期间为300 V的近似恒定电压。时间分辨电流，电场，电子密度，和时空激发率进行比较，在相同的放电条件下的实验和建模结果。通过这种协同方法，放电的发展和不同的电子动力学的不同阶段被识别和理解。
The electron dynamics in a nanosecond-pulsed microdischarge in high pressure hydrogen gas is investigated space and time resolved by particle-in-cell simulations. The discharge is driven by a 10 ns voltage pulse with a peak of 1.3 kV followed by an approximately constant voltage of 300 V during 150 ns. The time resolved current, electric field, electron density, and spatio-temporal excitation rates are compared to experimental and modeling results under identical discharge conditions. Via this synergistic approach, the development of the discharge and the different phases of distinct electron dynamics are identified and understood.
