The Application of 1-D X-ray Imaging System in Wire-Array Z-pinch Implosions

A time-resolved 1-D x-ray imaging system is developed to investigate the x-ray power distribution with one-dimensional space and continuous time resolution in wire-array Z-pinch experiments performed on Angara-5-1 facility.In these experiments various loads were used including nested-wire array and single array.The double-array implosion had a better axial implosion uniformity and synchronization than the single-array implosion,as well as the higher peak radiated x-ray power.It is shown that better synchronization and faster rise-time corresponds to higher x-ray radiation power,while better axial synchronization corresponds to faster rise-time.Furthermore,analysis indicates some relationship between a better implosion synchronization and a higher x-ray power.Higher x-ray radiation power and imploding kinetic energy obviously have something to do with higher load current.
