Characteristics of tungsten wire array Z-pinch implosion radiation on PTS
摘要
Abstract
This paper addresses parameters and setup of diagnostics for Z-pinch study on PTS. Experimental results of sin gle and nested wire array Z-pinch implosion dynamics and radiation characteristics are presented, with wire number in a range from 132 to 300,wire diameter in a range from 5 to 10 ,wire array diameter in a range from 13 to 30 mm. Experimental re sults reveal that, stagnation time of W wire array Z-pinch agree with 0-D thin shell calculation,however implosion trajectories di verges. Acceleration inferred by trajectory starts at about 67% of implosion time, thus indicates an ablation dominated pinch. With increasing of load linear mass and initial radius, load current increases, implosion time increases correspondingly. Mean while,X-ray pulse width increases and peak power decreases. Comparing implosion images of single and nested array, better uni formity and simultaneity are produced with nested array implosion,with an enhancement of peak radiation power. Total radiation energies produced by single array and nested array are comparable, with an energy conversion ratio of 15%0 Preliminary results of dynamic hohlraum study and a comparison to wire array Z-pinch experiment are presented.关键词
