One-dimensional x-ray imaging using a spherically bent mica crystal at 4.75 keV

One-dimensional x-ray imaging of static gold bars using a spherically bent mica crystal is presented for the first time at an x-ray energy of 4.75 keV. X rays are produced using 1-ns-square pulses on the TRIDENT laser facility driving the He-like resonance transition in solid titanium disks. Time-integrated images of square profile parallel gold bars are recorded on direct exposure film with a magnification of ∼10. Rising edge measurements of the bars demonstrate resolutions of about 6–7 μm over a 400 μm field of view.
