    New method of observing nonlinear waves in a plasma (1986)
    [S.l.] : American Institute of Physics (AIP)

    Notes: A new method for observing a nonlinear wave is proposed and illustrated with sample measurements. Observations are performed by using the time-of-flight method by counting the temporal upper hybrid wave packets which pass through the gap between two antennae. Two types of nonlinear waves were found in the experiment. One is outlined in the Korteweg de Vries equation by its behavior through the dispersion relation and the other behaves as a shock wave which represents the relaxing oscillation. The method of observation and the characteristics of the nonlinear waves are discussed circumstantially.

    Piezoelectrically driven XYθ table for submicron lithography systems (1989)
    [S.l.] : American Institute of Physics (AIP)

    Notes: A newly designed piezoelectrically driven XYθ table has been developed for submicron lithography systems. The XYθ table was fabricated using a monolithic plate structure, joined together with flexure hinges and driven by an inchworm function. This function involves the periodic clamping and unclamping of four blocks and the expansion and contraction of piezoelectric actuators. The XYθ table can travel a long distance with fine positioning in the X, Y, and θ directions. The velocities can be controlled up to 0.5 mm/s in the X and Y directions, and 0.3×10 −2 rad/s in the θ direction by changing the inchworm function stepping rate. Positioning accuracy of less than 1 μm in the X and Y directions, and 7.5×10−6 rad in the θ direction can easily be obtained using a servo system with a 0.5-μm measuring resolution.

    Characteristics and structure of an axially symmetric plasma echo (1985)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Fluids 28 (1985), S. 3269-3279

    Topics: Physics
    Notes: An axially symmetrical spatial plasma echo is obtained theoretically by using the Vlasov–Poisson equation system. Several features of the echo are studied by making use of this echo solution. Common linear relations between exciter grid separation l and the position of echo-amplitude maximum le are shown, and an influence of l on the amplitude is also obtained. The radial extent of the echo and the effects of the magnetic field and the plasma temperature on the echo are discussed. Most importantly, the existence of the fine structure of the echo, such as the appearance of a side lobe (besides the main lobe) in the amplitude curve and the presence of a phase gap on the interferometric phase trace were demonstrated by their appearance in this experiment. Good agreement is obtained between theory and the experimental results concerning the side lobes and the phase gaps.
