“…Total length is 15 m and the accelerator part is 8 m. The width of the RANS area is 8 m. Protons are accelerated up to an energy of 7 MeV with a maximum average current of 100 μA by an Model PL-7 linear accelerator by AccSys Technology Inc. Figure 2 shows a sketch of the setup from the target station to the camera box. The protons bombard a beryllium target 15) at the center of the target station and then neutrons of with a an energy of MeV order are generated via the Be(p,n) reaction. The neutrons are slowed by hydrogens in a moderator, downstream, of the beryllium target, which is made of 40 mm-thick polyethylene.…”

“…Thus care must be taken for the (often windowless) entrance of the incident beam and for the protection of the target against damage by heat deposition, radiation shock, and accumulation of gaseous hydrogen at the end of the range of charged particles in the target material. For example, the damage caused by the end-of-range stopping, evidenced by the well-known "Bragg peak" (not the diffraction peak), of incident protons in beryllium metal is well documented [15] . A few at.…”

Since the discovery of the neutron in 1934 neutron beams have been used in a very broad range of applications, As an aging fleet of nuclear reactor sources is retired the use of compact accelerator-driven neutron sources (CANS) are becoming more prevalent. CANS are playing a significant and expanding role in research and development in science and engineering, as well as in education and training. In the realm of multidisciplinary applications, CANS offer opportunities over a wide range of technical utilization, from interrogation of civil structures to medical therapy to cultural heritage study. This paper aims to provide the first comprehensive overview of the history, current status of operation, and ongoing development of CANS worldwide. The basic physics and engineering regarding neutron production by accelerators, target-moderator systems, and beam line instrumentation are introduced, followed by an extensive discussion of various evolving applications currently exploited at CANS.

Under the JST-ERATO project in progress to develop X-ray and neutron phase-imaging methods together, recent achievements have been selected and reviewed after describing the merit and the principle of the phase imaging method. For X-ray phase imaging, recent developments of four-dimensional phase tomography and phase microscopy at SPring-8, Japan are mainly presented. For neutron phase imaging, an approach in combination with the time-of-flight method developed at J-PARC, Japan is described with the description of new Gd grating fabrication.
