High resolution hard x-ray spectroscopy of femtosecond laser-produced plasmas with a CZT detector

چکیده
We present measurement of characteristic Ka emission from Mo, Ag, and La targets irradiated by a 60 fs, 600 mJ, 10 Hz Ti:sapphire laser pulse at 10– 10 W/cm. These x-ray emissions can potentially be used in applications from laser-based hard x-ray sources to x-ray mammography so detailed knowledge of the spectra is required to assess imaging of the figure of merit. We show here that high resolving hard x-ray spectroscopy can be achieved, with resolving powers (E/DE) of 60 at 18 keV, with cadmium–zinc–telluride detection system. The Ka conversion efficiency from the laser light to the Ka photon was optimized thanks to this diagnostic and values as high as 2 310 were obtained. © 2003 American Institute of Physics. @DOI: 10.1063/1.1628824#

The Cadmium Zinc Telluride (CZT) Detector Array Innovation Pathway
This pathway describes the development of soft gamma-ray/hard x-ray detector arrays at NASA’s Goddard Space Flight Center (GSFC, or Goddard), through a collaboration between the gamma-ray spectroscopy group and the detector branch. The Cadmium Zinc Telluride (CdZnTe, or CZT) detectors which resulted from this decade-long development were first flown on the wildly successful SWIFT mission in 200...

The CZT detector on the InFOCμS hard X-ray telescope is a pixellated solid-state device capable of imaging spectroscopy by measuring the position and energy of each incoming photon. The detector sits at the focal point of an 8m focal length multilayered grazing incidence X-ray mirror which has significant effective area between 20–40 keV. The detector has an energy resolution of 4.0 keV at 32 k...
متن کاملX-Ray Crystal Spectroscopy of Sub-picosecond Laser-Produced Plasmas beyond 50 keV.
The interaction of a sub-picosecond (sub-ps) laser with a high-Z target produces a hard x-ray continuum, but to our knowledge no high-resolution study of the line emission is known. We present here crystal spectroscopy as a tool for the observation of energetic line x-radiation from a sub-ps laser-produced plasma. Reflection properties of flat and bent crystals for x-ray spectroscopy are analyz...

Introduction: In nuclear medicine, the use of a pixelated semiconductor detector such as CZT is an of growing interest for introducing new devices. Especially, the spatial resolution can be improved by using a pixelated parallel-hole collimator with equal holes and pixel sizes based on the pixelated detector. The purpose of this study was to compare the effect of pixelated and ...
