A compact focusing crystal spectrometer based on the von Hamos scheme is described. Cylindrically curved mica and graphite crystals with a radius of curvature of Rϭ20 mm are used in the spectrometer. A front illuminated charge-coupled device ͑CCD͒ linear array detector makes this spectrometer useful for real-time spectroscopy of laser-produced plasma x-ray sources within the wavelength range of ...
The s and t dependence of incoherent +(3100) photoproduction from deuterium has been measured at the Stanford Linear Accelerator Center. $(3'700) photoproduction and #(3100) photoproduction from hydrogen have also been measured,Two narrow resonances have recently been discovered, the $(3100) and the zjJ(3700). l Since the original discovery, the $(3100) has been observed in photo-production by ...
Electron-positron pairs, produced in intense laser-solid interactions, are diagnosed using magnetic spectrometers with image plates, such as the National Ignition Facility (NIF) Electron Positron Proton Spectrometers (EPPS). Although modeling can help infer quantitative value, accuracy of models needs to be verified ensure measurement quality. The dispersion low-energy electrons and positrons m...
Electron momentum spectroscopy is a coincidence technique that measures the spectral momentum density of matter. In this paper we outline the theoretical framework underlying these measurements, give a description of the spectrometer, and show in detail the information this technique can provide for the prototypical material silicon. We present results for single crystals as well as amorphous s...
