Title: Sub-nanosecond single line-of-sight (SLOS) x-ray imagers (invited)

Abstract

A new generation of fast-gated x-ray framing cameras have been developed that are capable of capturing multiple frames along a single line-of-sight with 30 ps temporal resolution. The instruments are constructed by integrating pulse-dilation electron imaging with burst mode hybrid-complimentary metal-oxide-semiconductor sensors. Two such instruments have been developed, characterized, and fielded at the National Ignition Facility and the OMEGA laser. These instruments are particularly suited for advanced x-ray imaging applications in Inertial Confinement Fusion and High energy density experiments. Here, we discuss the system architecture and the techniques required for tuning the instruments to achieve optimal performance. Characterization results are also presented along with planned future improvements to the design.

Figures / Tables:

FIG. 1 FIG. 1: Schematic of system operation. (1) X-rays generate photoelectrons at the photocathode. (2) The photoelectrons are accelerated by a time dependent, spatially invariant electric field, produced by colliding avalanche pulses (see Secs. II A and II B). (3) The accelerated electrons undergo cyclotron motion as they propagate through themore » drift region (see Sec. II C). (4) Electrons are dispersed such that the pulse duration is ∼50× greater than the input x-ray pulse. (5) Electrons are accelerated by the boost region and impinge on the CMOS detector (see Sec. II D). (6) The CMOS detector collects the dilated electron pulse over several frames with ns frame widths.« less
