The amount of C in steel, which is critical in determining its properties, is strongly influenced by steel production technology. We propose a novel method of quantifying the bulk C content in steel non-destructively using muons. This revolutionary method may be used not only in the quality control of steel in production, but also in analyzing precious steel archaeological artifacts. A negatively charged muon forms an atomic system owing to its negative charge, and is finally absorbed into the nucleus or decays to an electron. The lifetimes of muons differ significantly, depending on whether they are trapped by Fe or C atoms, and identifying the elemental content at the muon stoppage position is possible via muon lifetime measurements. The relationship between the muon capture probabilities of C/Fe and the elemental content of C exhibits a good linearity, and the C content in the steel may be quantitatively determined via muon lifetime measurements. Furthermore, by controlling the incident energies of the muons, they may be stopped in each layer of a stacked sample consisting of three types of steel plates with thicknesses of 0.5 mm, and we successfully determined the C contents in the range 0.20 - 1.03 wt% depth-selectively, without sample destruction.

Muon irradiation of standard bronze samples was performed to determine the muon capture probabilities for the elemental components from muonic X-ray spectra. Nondestructive elemental analysis of an ancient Chinese coin was also performed.

Times Cited Count:1 Percentile:50.39The Experimental Physics and Industrial Control System (EPICS) provides software infrastructure and framework for building distributed control systems (DCS) to operate beam line devices. The DCS based on EPICS has been adopted by many accelerator facilities in the world, where reliability, maintainability, and scalability of the system have been demonstrated. This system is also used to operate the high energy proton accelerator in the Japan Proton Accelerator Research Complex (J-PARC). We here report on the EPICS-based remote control system developed for operating the decay muon beam line in J-PARC. Major functions of beam line devices, three bending magnets, eighteen quadrupole magnets, and four slits, are accessible via Ethernet from a graphical user interface composed of the Motif Editor and Display Manager (MEDM).

Times Cited Count:53 Percentile:86.96(Physics, Multidisciplinary)We report zero-field SR measurements made at J-PARC on CeRuAl. Below the phase transition temperature K, a clear modulation of polarization due to an internal field is observed, indicating that magnetic ordering takes place. Compared with the internal field expected from the effective magnetic moment in the disordered state, the observed internal field at the site is quite small. This indicates that the ordered Ce magnetic moment is small () and/or the nearest pair of Ce magnetic moments are mutually anti-parallel. The -dependence of the internal field is somewhat peculiar, suggesting that another ordering is taking place as well.
