Proton radiography is used for advanced hydrotesting as a new type radiography technology due to its powerful penetration capability and high detection efficiency. A new proton radiography terminal will be developed to radiograph static samples at Institute of Modern Physics of Chinese Academy of Science (IMP-CAS). The proton beam with the maximum energy of 2.6 GeV will be produced by Heavy Ion Research Facility in Lanzhou-Cooling Storage Ring (HIRFL-CSR). The proton radiography terminal consists of the matching magnetic lens and the Zumbro lens system. In this paper, the design scheme and all optic parameters of this beam terminal for 2.6GeV proton energy are presented by simulating the beam optics using WINAGILE code. My-BOC code is used to test the particle tracking of proton radiography beam line. Geant4 code and G4beamline code are used for simulating the proton radiography system. The results show that the transmission efficiency of proton without target is 100%, and the effect of secondary particles can be neglected. In order to test this proton radiography system, the proton images for an aluminum plate sample with two rectangular orifices and a step brass plate sample are respectively simulated using Geant4 code. The results show that the best spatial resolution is about 36μm, and the differences of the thickness are not greater than 10%.

“…This achieved a position resolution of 50 µm over 2 cm in the object plane. There is also a proton radiography facility [165] at the U-70 proton accelerator at IHEP in Protvino that has been operating since 2004 [166][167][168]; this is currently the highest-energy proton radiographic facility available. The proton energy can be selected up to a maximum of 70 GeV, with a high bunch intensity capability (up to 1.5 × 10 13 protons per cycle, with a multiframe capability of up to 29 frames separated by 169 ns (see Fig.…”

Particle beam radiography, which uses a variety of particle probes (neutrons, protons, electrons, gammas and potentially other particles) to study the structure of materials and objects noninvasively, is reviewed, largely from an accelerator perspective, although the use of cosmic rays (mainly muons but potentially also high-energy neutrinos) is briefly reviewed. Tomography is a form of radiography which uses multiple views to reconstruct a three-dimensional density map of an object. There is a very wide range of applications of radiography and tomography, from medicine to engineering and security, and advances in instrumentation, specifically the development of electronic detectors, allow rapid analysis of the resultant radiographs. Flash radiography is a diagnostic technique for large high-explosive-driven hydrodynamic experiments that is used at many laboratories. The bremsstrahlung radiation pulse from an intense relativistic electron beam incident onto a high-Z target is the source of these radiographs. The challenge is to provide radiation sources intense enough to penetrate hundreds of g/cm 2 of material, in pulses short enough to stop the motion of high-speed hydrodynamic shocks, and with source spots small enough to resolve fine details. The challenge has been met with a wide variety of accelerator technologies, including pulsed-power-driven diodes, air-core pulsed betatrons and high-current linear induction accelerators. Accelerator technology has also evolved to accommodate the experimenters' continuing quest for multiple images in time and space. Linear induction accelerators have had a major role in these advances, especially in providing multiple-time radiographs of the largest hydrodynamic experiments.

“…Existing proton radiography facilities in the U.S. (LANSCE) [4,5] and in Russia [1][2][3] clearly showed the advantage of proton radiography compared to conventional X-ray methods, in studies of dense objects, especially in dynamic experiments. The best spatial resolution for the study of proton radiography was obtained at facilities by increasing image of the objects, constructed according to the scheme of the proton microscope [5].…”

The proton radiography facility which uses magnetic optics (proton microscope PUMA [7]) was developed at TWAC-ITEP accelerator [1,2,6]. PUMA proton microscopy facility was specially designed for studies in the field of high energy density physics, including the research of equations of state and phase transitions of matter at extreme conditions, shockwave and detonation physics, hydrodynamics of high energy density flows, and dynamic material strength and damage studies [10,11]. Proton microscope PUMA allows the measurement of density distribution within static and dynamic objects by using a proton beam with energy of 800MeV. Protonradiographic image of the object is formed in the plane of the detector with magnification k=4. An image of the object is formed using a magneto-optical system consisting of four quadrupole lenses on permanent magnets (PMQ). PUMA facility is designed for the measurement of objects with areal density of 20 g/cm 2 and field of view of 20 mm. For the facility, the spatial resolution is from 60 microns to 115 microns for objects with areal density from 0.46 g/cm 2 to 17 g/cm 2 , respectively. Research was also performed on nondestructive testing of static objects (including tomographic methods) and radiobiological studies.
