Abstract

Abstract

A series of magnetically driven flyer plates experiments were performed on Yang accelerator with electrode material of LY-12 alloy and stainless steel. By changing the module parameters, we can acquire the desired current waveform for launching flyer plates shocklessly on stripline and coaxial load configurations. Considering the efficiency factor of current history, we calculated the free-surface velocity and flyer velocity history, which were in good agreement with the measured results. In addition, with current calculation model which considered variable load inductance, we calculated load current and flyer velocity which were also in agreement with the measured results. In this way, we could design an optimized load configuration that minimized the axial variation of the striplines magnetic pressure. Furthermore, we can predict sample stress history and flyer velocity on more powerful pulse facility.
