Summary
At first stage of work was developed the metal plate launcher stend. This stend will be used for testing of different types of Doppler velocimeters and allow to launch metal disc with speed more than 300 m/s. The spiral inductance launcher is made of copper wire and have 7 mkH self-inductance. Capacitor bank with capacity from 3 o 12 μF discharged by the thyratron TGI-1-150k/25 and produce current up to 15 kA in inductance. Ponderomotive force drives the object into motion. To measure the velocity of metal plate, the shadowgraphy method was used. To decrease aerodynamic resistance inductance was plaсed in a vacuum chamber. This setup allow to test and calibrate non-equal-shoulder interferometer with polarizable modulation of a signal (push-pull VISAR) (Fig. 1).
