A Time-Resolved Imaging System for the Diagnosis of X-ray Self-Emission in High Energy Density Physics Experiments
arXiv:2111.11324 · doi:10.1063/5.0073174
Abstract
A diagnostic capable of recording spatially and temporally resolved X-ray self emission data was developed to characterise experiments on the MAGPIE pulsed-power generator. The diagnostic used two separate imaging systems: A pinhole imaging system with two dimensional spatial resolution and a slit imaging system with one dimensional spatial resolution. The two dimensional imaging system imaged light onto image plate. The one dimensional imaging system imaged light onto the same piece of image plate and a linear array of silicon photodiodes. This design allowed the cross-comparison of different images, allowing a picture of the spatial and temporal distribution of X-ray self emission to be established. The design was tested in a series of pulsed-power driven magnetic-reconnection experiments.
