“…The advantages of high energy proton and heavy ion radiography over conventional radiography lie in many aspects, in particular by ensuring much longer penetrating distance, higher spatial resolution, better sensitivity to material density, and a large dynamic range of imaging. Proton/heavy ion radiography is a new powerful tool not only for industrial applications, such as nondestructive inspection of bulk materials, but also for medical diagnosis (Shafranova & Shafranov, 1980;Ten et al, 2005;Toyokawa et al, 2002). Heavy ion radiography has been applied at the Lawrence Berkeley Laboratory for human tissues diagnosis (Benton et al, 1973;Fabrikant et al, 1982).…”

In this work, we review current trends in China to investigate beam plasma interaction phenomena. Recent progresses in China on low energy heavy ions and plasma interaction, ion beam-plasma interactions under the influences of magnetic fields, high energy heavy ion radiography through marginal range method, energy deposition of highly charged ions on surfaces and Raman spectroscopy of surfaces after irradiation of highly charged ions are presented.

“…The LCS ␥-ray source can generate the energy tunable quasimonochromatic ␥-rays [6][7][8][9] and have been used for studying nuclear physics 10,11 and industrial applications. 12 We have proposed an assay method of elemental and isotopic composition of materials hidden by heavy shields by measuring nuclear resonance fluorescence ͑NRF͒ scattering ␥-rays with a LCS ␥-ray source ͑see Fig. 1͒.…”

A nondestructive assay method for measuring a shielded chemical compound has been proposed. The chemical compound is measured by using a nuclear resonance fluorescence (NRF) measurement technique with an energy tunable laser Compton-scattering (LCS) gamma-ray source. This method has an advantage that hidden materials can be detected through heavy shields such as iron plates of a thickness of several centimeters. A detection of a chemical compound of melamine, C(3)H(6)N(6), shielded by 15-mm-thick iron and 4-mm-thick lead plates is demonstrated. The NRF gamma-rays of (12)C and (14)N of the melamine are measured by using the LCS gamma-rays of the energies of up to 5.0 MeV. The observed ratio ((12)C/(14)N)(exp)=0.39+/-0.12 is consistent with (C/N)(melamine)=0.5.

“…They imaged several objects made of either low Z (concrete) or high Z (Pb, Fe, Cu) materials, or a combination of the two. 6,27,28 The best spatial resolution attained using 10 MeV LCS photons was 650 µm. Similar results were obtained at the HIγS facility, where, using CCD-based gamma camera detection, they demonstrated a lateral resolution of 0.5 mm and a contrast sensitivity better than 6%.…”

The Nuclear Physics oriented pillar of the pan-European Extreme Light Infrastructure (ELI-NP) will host an ultra-bright, energy tunable, and quasi-monochromatic gamma-ray beam system in the range of 0.2-19.5 MeV produced by laser Compton backscattering. This gamma beam satisfies the criteria for large-size product investigations with added capabilities like isotope detection through the use of nuclear resonance fluorescence (NRF) and is ideal for non-destructive testing applications. Two major applications of gamma beams are being envisaged at ELI-NP: industrial applications based on NRF and industrial radiography and tomography. Both applications exploit the unique characteristics of the gamma beam to deliver new opportunities for the industry. Here, we present the experimental setups proposed at ELI-NP and discuss their performance based on analytical calculations and GEANT4 numerical simulations. One of the main advantages of using the gamma beam at ELI-NP for applications based on NRF is the availability of an advanced detector array, which can enhance the advantages already provided by the high quality of the gamma beam.
