Experimental study of conical liner magnetic implosion [pulsed power technology]

Conical aluminium liner magnetic implosion, focalization on axis and subsequent high velocity matter emission were analysed through a VNIIEF/CEA joint experiment realized in Sarov. The experiment results are described in the present paper. Liner focalization and jet formation were to be analyzed through radiographic transverse observation. X-ray flashes were realized at expected two times values, which were only distant by 400 ns. The pictures quality is excellent. This experiment was a challenge both for generator performance (achieve high value of current in EMG and ability to transfer it to chamber) and for hydrodynamical purpose (first flight of conical liner and focalization to axis). For such a new and complex topic, experimental results exhibit very nice agreement with prediction calculations.
