摘要: Observations of complex plasmas under microgravity conditions onboard the International Space Station performed with Plasma-Kristall experiment-Nefedov facility are reported. A weak instability boundary between central void sregion free microparticlesd and microparticle cloud is observed at low gas pressures. The leads to periodic injections a relatively small number particles into region sby analogy this effect called “trampoline effect” d. trajectories injected analyzed providing information on force field inside void. experimental results compared theory which assumes that most important forces electric ion drag forces. Good agreement found clearly indicating investigated formation caused by force.
