The Experimental Block is shown in the figure. It can be divided into three different parts: Part I : Experimental setup. Includes the rf plasma chamber ( 3 , see also Fig.2), a symmetrical parallel plate reactor filled with argon with assembled microparticle dispensers ( 2 = dispenser drive), rf-generator ( 7 ), pressure control system ( 9 ), cameras ( 4 ), and lasers ( 8 ) mounted on a translation stage. The rf generator is a special development for lowest rf power values, which are required for stable and large complex plasma systems and for plasma crystal formation. Two CCD-cameras provide two different magnifications of the complex plasmas. The overview camera shows about a quarter of the fie ld between the electrodes, 28.16 x 21.45 mm 2 , while the high resolution camera is used for detailed views inside the overview field covering 8.53 x 6.50 mm 2 . On top of the Experimental Block a vacuum connection ( 6 ) is used to pump the experimental setup. This vacuum port is contacted to outer space. Part II : Electronics ( 5 , 10 ) for part I and the system electronics (PC, video and main power control). Part III : Experiment computer. Allows real time control of the plasma. Electrical signals produced by the experiment computer and the two video signals are contacted out of the container ( 1 ) and are controlled by the Telescience Module (see Fig.4). The computer visualizes the experimental data and can be used to control the experiment manually. Time codes (VITC signals) are inserted into the video frames and stored on two High-8 video recorders. The original video tapes are transferred to ground by the cosmonauts. The Telescience Module has the capability to transfe r experimental data and video to ground and receive commands from ground, allowing full telescience control of the experiment by the scientists. Monodisperse particles of different sizes — 3.4 �m and 6.8 �m in diameter, as well as a mixture of both sizes — can be injected into the plasma chamber, between the two electrodes. The microparticles are illuminated by a thin (~150 �m) sheet of laser light perpendicular to the electrode system (produced by a laser diode and cylindrical optics). For each particle size one laser is installed, which is adjusted in power and optics to achieve best results. The reflected light from the microparticles is observed with two monochromatic video CCD-cameras (768 x 576 pixels, 25 Hz, 8-Bit) with different resolution. The microparticles can be identified in a single video frame and are then followed in time to investigate their dynamical behaviour. The frame rate is 25 Hz, which is faster than the complex plasma frequency of ~10 Hz. Slow spee d scanning of the laser and optics into the depth of the plasma chamber is used to measure the 3D positions of the microparticles. MPE: PKE-Nefedov - Hardware hier
