Research paper−90−Synthesiology - English edition Vol.8 No.2 pp.90-96 (Sep. 2015) quickly according to the decision made.This paper consists of four chapters. In chapter 2, technical issues will be discussed. Chapter 3 discusses the process of selection and integration of technologies for bridging, in correspondence to (1) ~ (3) listed above. Chapter 4 reflects on the process of selection and integration of the elemental technologies in correspondence to (4), and discusses the efforts spent to achieve the goals and results.2 Technical issues about laser Compton scatteringThere are attractive technologies in nuclear physics and elementary particle physics especially in radiation measurement technologies. They are highly sophisticated, and can be applied to industrial technology with some modifications. We applied a method for measuring cross-sections of atoms and nuclear reactions to nondestructive testing via industrial radiography. Industrial radiography is an important technique in improving reliability of industrial products such as automobiles, aircraft, rockets, sintered materials, cast products, and electronic substrates.[1] A high-energy X-ray computerized tomography (CT) system using an electron accelerator that is capable of radiographing a whole engine block at spatial resolution of 2~3 mm has been developed. In infrastructure diagnosis, the technology to inspect roadbeds and bridges on site using a portable electron accelerator has been developed recently.[2] A nondestructive and highly precise method for visualizing reinforcing steel-bars and cracks in concrete structure is strongly demanded in our society.1 IntroductionTranslational research is a process in which scientific knowledge for basic research is translated into practical application for the benefit of society. While we attain the objectives of research, we take several issues into account, such as schedule, quality of research output, funding, cost efficiency for investment, objectives of the organization, and the voice of society. Technical level might be lowered if we easily compromised to produce outcomes in a short time, or we may become isolated from society if we keep pursuing our own way.The objective of this paper is to show how a basic research study in an electron accelerator translated into industrial technology. The translation process is not to improve the device performance or produce champion data, but is to bridge research results to industry in an appropriate form. The present research consists of the following scenario:(1) Development and compilation of elemental technologies.(2) Open to users: Device open to users to estimate potential users by listening to the users’ voices.(3) Investigation of plan: To investigate the research plan by objectively understanding the users’ voices on whether the obtained results were as expected initially, what was overlooked if the results were not as expected, or whether there were better ways.(4) Modification of plan: To organize the main points of future devices and technologies. To determine whether the research will be continued by considering the cost-effectiveness and the situation of the organization. To act - A spin-off technology from nuclear physics-Laser Compton photon beams generated by a high-energy electron storage ring have energy in the gamma-ray range. X-ray radiography for industrial products using the laser Compton photon beam is expected to show good spatial and density resolutions, because of its monochromaticity and good beam property. A radiography and computerized tomography system was built using AISTʼs TERAS electron storage ring. The performance of the system was examined. A summary of the development process is outlined to figure out the general methodology for translational research.
