    Operational Requirements

    Experimental Tenzor unit, Turbopump, Telescience equipment to control the process and record experiment results.

    Experimental unit "Plasma crystal 3", two TEAC video tape recorders, included in the on-board "Telescience" equipment.

    Operational Protocols

    Study of physical phenomena in plasma-dust crystals at different pressure levels of inert gas and power of HF generator in microgravity environment.

    Conducting two series of measurements that are needed to study the physics of the particles contained in low-pressure plasma, and to study quasi-stable plasma structures formed out of these particles.

    Results/More Information

    Development of procedure for generation and monitoring of ordered structures of charged solid dust microparticles in plasma.

    Video recording of plasma crystal formation process, along with the digital data on the experiment, are returned to Earth. Parameters such as gas pressure, high-frequency radiated power and the size of dust particles from which the crystal is formed are written to PCMCIA card and returned.
