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.

The AIRIX 1 facility is a high current linear accelerator used for flash-radiography at the CEA of Moronvilliers (France)[1] [2]. This accelerator has been designed to generate an intense X-ray pulse of 500rads at 1m, using a 2kA, 20MeV, 60ns electron beam. This beam is created by an injector that delivers a 2kA, 3,5 to 3,8MeV, 60ns electron beam, and 64 induction cells powered by 32 high voltage generators. Each of this cells adds 250keV to the beam. After each trial, the signals picked up are checked to determine local problems. Our aim is to highlight the slow drifts of the performances of the facility which are not directly observable by the operators. We concentrate first on the high voltage generators to build our analysis. The final objective of our study is to develop signal processing tools for predictive maintenance of the whole AIRIX induction accelerator. We have set up a monitoring procedure based on two complementary methodologies. In the first one, relevant features are extracted from electrical signals of the facility, and statistical analysis are made on them. Results should improve the understanding of the functioning of the facility. The second one is based on a global analysis of the signal. We detect in the time-frequency plane the place of signal evolutions between two periods, making the analysis easier for the operators.
