Advanced hCMOS Systems

Electron tubes continue to provide the highest speeds possible for recording dynamics of hot high-energy density plasmas. Standard streak camera drive electronics and CCD readout are not compatible with the radiation environment associated with high DT fusion yield inertial confinement fusion experiments >10 ¹³ 14 MeV DT neutrons or >10 ⁹ n cm ⁻² n...

The hardened single line of sight camera has been recently characterized in preparation for its deployment on the National Ignition Facility. The latest creation based on the pulse-dilation technology leads to many new features and improvements over the previous-generation cameras to provide better quality measurements of inertial confinement fusio...

Framing cameras provide a discrete series of images over a short period of time in a manner that mimics a high-speed movie camera but with individual shutter times that must be extremely short in order to capture freeze-frame images of rapidly evolving phenomena such as high-explosive shock-driven ejecta, dynamic compression of metals, and high-vel...

A major upgrade has been implemented for the ns-gated laser entrance hole imager on the National Ignition Facility (NIF) to obtain high-quality data for Hohlraum physics study. In this upgrade, the single “Furi” hCMOS sensor (1024 × 448 pixel arrays with two-frame capability) is replaced with dual “Icarus” sensors (1024 × 512 pixel arrays with four...

In this paper, the authors report the latest results on their development of superlattice-doped, thinned, backside-illuminated (BSI), 3D-integrated photodiode detectors—a step toward their ultimate goal of demonstrating ultrafast, ultrastable CMOS imaging arrays. As with most silicon-based photodetectors, backside-illumination and backside surface...

Silicon detectors are an essential measurement tool for Inertial Confinement Fusion and High-Energy-Density Physics Applications, where temporal response of the order of nanoseconds is essential. Soft X-rays (<1 keV), Ultraviolet light, and low-energy electrons (<10 keV) can provide essential information in diagnosing rapidly changing plasma condit...

The single-line-of-sight, time-resolved x-ray imager (SLOS-TRXI) on OMEGA is one of a new generation of fast-gated x-ray cameras comprising an electron pulse-dilation imager and a nanosecond-gated, burst-mode, hybrid complementary metal-oxide semiconductor sensor. SLOS-TRXI images the core of imploded cryogenic deuterium–tritium shells in inertial...

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 instrument...

Crystal x-ray imaging is frequently used in inertial confinement fusion and laser-plasma interaction applications as it has advantages compared to pinhole imaging, such as higher signal throughput, better achievable spatial resolution, and chromatic selection. However, currently used x-ray detectors are only able to obtain a single time resolved im...

A novel x-ray imager, which takes time-resolved gated images along a single line-of-sight, has been successfully implemented at the National Ignition Facility (NIF). This Gated Laser Entrance Hole diagnostic, G-LEH, incorporates a high-speed multi-frame CMOS x-ray imager developed by Sandia National Laboratories to upgrade the existing Static X-ray...

The Hippogriff camera developed at Sandia National Laboratories as part of the Ultra -Fast X -ray Imager (UXI) program is a high -speed, multi -frame, time -gated imager for use on a wide variety of High Energy Density (HED) SK\VLFVH[SHULPHQWVRQERWK6DQGLD¶V= -Machine and the National Ignition Facility .

We present a characterization technique for nanosecond gated CMOS cameras designed and built by SandiaNational Laboratory under their Ultra-Fast X-ray Imager program. The cameras have been used to recordimages during HED physics experiments at Sandia's Z Facility and at LLNL's National Ignition Facility. Thebehavior of the camera's fast shutters wa...

The Ultra-Fast X-ray Imager (UXI) program is an ongoing effort at Sandia National Laboratories to create high speed, multi-frame, time gated Read Out Integrated Circuits (ROICs), and a corresponding suite of photodetectors to image a wide variety of High Energy Density (HED) physics experiments on both Sandia’s Z-Machine and the National Ignition F...

Gated x-ray images through the laser entrance hole (LEH) of a hohlraum can provide critical information for ICF experiments at the National Ignition Facility (NIF), such as the size of the LEH vs time, the growth of the gold bubble, and the change in the brightness of inner beam spots due to time-varying cross beam energy transfer. Incorporating a...

High resolution (λ/δλ ˜10,000) 1D spatially resolved x-ray spectroscopy using a spherically bent crystal and a 2D hybrid pixel array detector is used world wide for Doppler measurements of ion-temperature and plasma flow-velocity profiles in magnetic confinement fusion plasmas. Meter sized plasmas are diagnosed with cm spatial resolution and 10 ms...

The concepts of a high-resolution x-ray imaging crystal spectrometer (XICS) and novel stigmatic imaging schemes for accurate measurements of x-ray line shapes and the x-ray emission profiles at the National Ignition Facility (NIF) will be presented. The XICS will allow measurements of the line shapes of x-ray lines from high-Z impurities, such as k...

In this paper, we describe a modified soft defect localization (SDL) technique, PSDL (pseudo-soft defect localization), to localize pseudo-soft defects in integrated circuits (ICs). Similar to soft defects, functional failures due to pseudo-soft defects are sensitive to operating parameters (such as voltages, frequencies and temperatures) and/or la...
