Fluctuation in the plasma needs to be measured for studying the improvement of the plasma confinement by the formation of the plasma confinement potential. A newly constructed multichannel microwave interferometer and ultrashort-pulse reflectometry were used for measuring the line integrated plasma density profile and density fluctuation profile in a few plasma shots. The first results of density and density fluctuation measurements in the central cell of the tandem mirror GAMMA 10 are described by using the multi-channel interferometer and ultrashort-pulse reflectometry.

Power-up of gyrotrons was carried out and corresponding launcher systems were designed for plug and central-cell ECRH systems in the GAMMA 10 tandem mirror. Then, a high-power ECRH experiment was started. For the plug ECRH, new 500-kW gyrotrons produced a new record value of the confining potential. For the central-cell ECRH, development of a new antenna system has increased the transmission rate of incident microwave power and focused it onto the machine axis in the resonance surface. As a result, a clear increase of the diamagnetism was observed during the pulse of ECRH.

A model is presented which can be used to explain the friction condition on the interface between the composites and the mold during sheet-like parts compression molding of fibre-reinforced thermoplastics. The composites is treated as an incompressible isotropic fluid. Circular hollow disk is compressed in order to derive the position of the neutral surface which can explain the interfacial friction from consideration of minimum energy dissipation. From the theory and the experiment, it is clear that there is slip at the mold surface. By using the nondimensional parameter which measures the ratio of vicous to frictional resistance, the phenomenon of the friction can be well explained.
