An x-ray streak camera with high spatio-temporal resolution

Abstract

An x-ray streak camera with high resolution in both temporal and spatial dimensions has been developed. It is achieved by using extraction-mesh acceleration and a large opening aperture magnetic solenoid lens design. High resolutions in the temporal and spatial dimensions can be retained in a wide 53ps time window. A temporal resolution of 233fs and a spatial resolution of 10μm have been demonstrated using a Au photocathode.

Ultrafast Imaging in Standard (Bi)CMOS Technology

“…The typical spatial resolution of a conventional streak camera is between 25 µm and 100 µm. Specific tube designs using magnetic solenoid lens can reach a spatial resolution of 10 µm (Feng et al, 2007). Finally their temporal resolutions are very close to the physical theoretic limitation, about 100 fs (Zavoisky & Fanchenko, 1965) but with a poor signal to noise ratio whereas 1 ps can be reached with a high signal to noise ratio (Uhring et al, 2004a).…”

Enabling instrumentation and technology for 21st century light sources

“…These approaches include electro-optic sampling [1,2], coherent synchrotron terahertz radiation [4], streak cameras [8,9], transverse deflecting structures [3], and fluctuational interferometry [5][6][7]. A comparison of these techniques is beyond the scope of this paper.…”
