Sixteen‐Frame Interferometer for a Study of a Pinch Dynamics in PF‐1000 Device

Abstract Multiframe laser interferometer system for studies of rapidly varying processes in dense, high‐temperature plasma in plasma‐focus device is described. The setup of sixteen‐frame interferometer contains the Mach‐Zehnder system and the completely new, innovative beams separator which allows obtaining sixteen interferometric frames in one discharge. Each interferogram is recorded separately with the same linear size and quality. Delay from the first to the last frame is 220 ns. The result obtained using this system is given. It demonstrates its quality and suitability for investigations of dynamics of fast, irreproducible processes in PF‐1000 (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
