Abstract

A diagnostic is proposed that uses the Doppler effect in visible-light emission lines to deduce the ion velocity during the implosion phase of a gas-puff z-pinch. The diagnostic combines an innovative light collection and detection scheme with gas doping to determine the ion velocities. The proposed instrument will be able to determine implosion velocities over a 100 ns range on a single shot using a series of charge states within the operating range of the detector. The temporal window of the instrument is sufficient to cover the dynamics of the implosion on the Double-Eagle simulator with a 300 ns electrical pulse. The Phase I will identify target ions and spectral ranges and include field-testing on Double Eagle.
