Application of Ultra-Fast High-Resolution Gated-Image Intensifiers to Laser Fusion Studies
Gated—image intensifiers for fast framing have found high utility in laser—target interaction studies in this laboratory. X—ray pinhole camera photographs which can record asymmetries of laser—target interactions have been instrumental in further system design. High—resolution high—speed x—ray images of laser irradiated targets are formed using pinhole optics and electronically amplified by proximity focused channelplate intensifiers before being recorded on film. Spectral resolution is obtained by filtering. In these applications shutter duration is determined by source duration. Electronic gating serves to reduce background thereby enhancing signal—to—noise ratio. Cameras are used to view the self light of the interaction but may also be used for shadowgraphs. Sources for shadowgraphs may be sequenced to obtain a series of pictures with effective rates of 1010 frames/s. Multiple apertures have been used to obtain stereo x—ray views, yielding three dimensional information about the interactions.
