Soft X-ray Production and Spectrum Measurements in Imploded Krypton Liners

摘要

Experiments on efficient conversion of the pulse generator energy to soft x rays were carried out on the MIG facility (I ～1.9 MA, τ ～80 ns). Krypton gas-puff liners were used to produce a pulse of N-shell and M-shell radiation (0.1-1 keV). A radiation yield of 50 ±5 kJ in ～30 ns was attained, which made up ～60% of the energy in the water transmission line. The x-ray power and time resolved spectrum was measured with an x-ray diode array. Both the deconvolution and edge filter techniques were used to obtain the spectra. Gas-puff filters were used to extend the spectral range of the XRD's to < 150 eV. It has been demonstrated that X-ray spectra can be adjusted by varying of the initial radius of the liner.
