Abstract
In order to enlarge the field of view of a multi-imaging x-ray streak (MIXS ) camera technique [H. Shiraga , Rev. Sci. Instrum. 66, 722 (1995)], which provides two-dimensionally space-resolved x-ray imaging with a high tempora l resolution of similar to 10 ps, we have proposed and designed a wide-fiel d MIXS (W-MIXS) by increasing the number of image-sampling arrays. In this method, multiple cathode slits were used on the photocathode of an x-ray st reak camera. The field of view of the W-MIXS can be enlarged up to 150-200 mum instead of similar to 70 mum for a typical MIXS with a spatial resoluti on of similar to 15 mum. A proof-of-principle experiment with the W-MIXS wa s carried out at the Gekko-XII laser system. A cross-wire target was irradi ated by four beams of the Gekko-XII laser. The data streaked with the W-MIX S system were reconstructed as a series of time-resolved, two-dimensional x -ray images. The W-MIXS system has been established as an improved two-dime nsionally space-resolved and sequentially time-resolved technique. (C) 2001 American Institute of Physics.
