Monte Carlo Simulations of Microchannel Plate–Based, Time-Gated X-ray Imagers
In the last two decades, high-speed, time-gated Microchannel plate (MCP) x-ray detectors have proven to be powerful diagnostic tools for two-dimensional, time-resolved imaging and time-resolved x-ray spectroscopy in the field of laser-driven inertial confinement fusion and fast Z-pinch experiments (McCarville et al., 2005; Oertel et al., 2006; Bailey et al., 2004). These detectors’ quantitative...
متن کاملThree-dimensional model of x-ray induced microchannel plate output
Microchannel plates are an important component in a type of imaging diagnostic known as an x-ray framing camera, used in x-ray radiography of high-energy-density physics experiments. A microchannel plate is responsible for detecting x rays and then converting them into amplified bursts of electrons, which are then imaged onto a phosphor-coated fiber optic screen. We present the preliminary deve...
متن کاملImaging X-Ray Fluorescence Using Microchannel Plate (MCP) Optics
X-ray fluorescence imaging is a widely used, nondestructive method for determining the distribution and relative concentration of metals within a sample. To create a two-dimensional map of an image, x-rays are usually sent through a 25-250 μm wide aperture, then point by point an image is scanned. Microchannel plates contain an array of tiny holes that can be used to collimate x-rays fluorescin...
متن کاملQuantitative extraction of spectral line intensities and widths from x-ray spectra recorded with gated microchannel plate detectors.
Plasma spectroscopy requires determination of spectral line intensities and widths. At Sandia National Laboratories Z facility we use elliptical crystal spectrometers equipped with gated microchannel plate detectors to record time and space resolved spectra. We collect a large volume of data typically consisting of five to six snapshots in time and five to ten spectral lines with 30 spatial ele...
متن کاملNote: Diagnosing femtosecond laser-solid interactions with monochromatic Kα imager and x-ray pinhole camera.
An x-ray pinhole camera and a monochromatic K(α) imager are used to measure the interactions of intense femtosecond laser pulses with Cu foil targets. The two diagnostics give different features in the spot size and the laser energy scaling, which are resulted from different physical processes. Under our experimental conditions, the K(α) emission is mainly excited by the fast electrons transpor...
