Radiography of hard X-ray produced by ultra-short ultra-intense laser-metal targets interactions

Radiography is one application of the hard X-ray derived from ultra-short ultra-intense(US-UI) laser-matter interactions. Experiments about hard X-ray production from US-UI laser interaction with high-Z metal targets, on SILEX-Ⅰ laser facility at National Key Laboratory of Laser Fusion have obtained radiographs. The radiograph receivers were sandwich detectors with scintillation layer and film and with scintillation and CCD. Radiograph’s quality and resolution vary obviously because of different scintillator thickness and magnification ratio. This radiography technique not only can be the basic method for investigating the advanced X-ray imaging source, but also can be the detection system for studying laser-solid target interactions.
