Streamer discharges in water were generated by repetitive and reliable pulsed power generators using magnetic pulse compression (MPC) circuits1. This work reports on observation by high speed cameras of the streamer progress, bubble production after plasma, phenomena of repetitive plasmas and probability of discharges by moving electrode.
We propose, design and fabricate here an electrostatically actuated continuous single-crystal-silicon membrane deformable mirror (DM) for astronomical observation. A 50μm air gap is generated a large between the mirror membrane and the electrode to get a large stroke. A DM with a 4mm×4mm mirror membrane and 8×8 underlying electrode array a is fabricated by combining Au-Si eutectic wafer bonding and...
This paper reports the piezoelectric properties of ScAlN thin films. We evaluated the piezoelectric coefficients d33 and d31 of ScxAl1−xN thin films directly deposited onto silicon wafers, as well the radio frequency (RF) electrical characteristics of Sc0.35Al0.65N bulk acoustic wave (BAW) resonators at around 2 GHz, and found a maximum value for d33 of 28 pC/N and a maximum −d31 of 13 pm/V at 40%...
We propose, design and fabricate here a novel electrostatically actuated continuous membrane deformable mirror for the next generation astronomical observation. To get a large stroke, a bimorph spring array is used to generate a large air gap between the mirror membrane and the electrode. A 3.4mm × 3.4 mm deformable mirror with a underlying 4×4 electrode array is fabricated by utilizing plasma activated...
Summary form only given. The paper describes the effects of an output peaking capacitor on the propagation of underwater streamer. A pulsed power modulator using a magnetic compression circuit was employed to generate 20 to 30 kV pulses with 2 microsecond pulse width. A point-to-plane electrode setup with 2 cm gap in tap water was used. A copper line with 0.4 mm tip diameter was used as the discharge...
