The Development of a Non-Destructive Analysis System with Negative Muon Beam for Industrial Devices at J-PARC MUSE

Abstract

Negative muons are important probes that enable us to investigate non-destructively the elemental composition in thick-layered samples. This method has already shown successful results for the elemental analysis of cultural heritage artifacts. Now, its success attracts also the interest of industrial device developers who want to know non-destructively the inside of a device during switch-on state. At J-PARC MUSE, in response to such needs, we have developed an analysis system with higher detection efficiency to increase opportunities for analyzing many new device samples. This report describes the chamber design and the results obtained from a first test experiment.

Nondestructive High-Sensitivity Detections of Metallic Lithium Deposited on a Battery Anode Using Muonic X-rays

“…This has naturally led to a proposal of a new elemental analysis technique using muonic X-rays, first suggested in the 1980s. , The first quantitative analysis using this technique, however, was reported in 2012 for archeological materials because the number of negative muons that could be produced had been very limited. Recently, 10 6 negative muons per second have been available as a pulse μ – beam at the Japan Proton Accelerator Research Complex (J-PARC), which has allowed numerous previously unachievable investigations involving elemental analyses using muonic X-rays. − This technique has also attracted significant attention from other muon facilities, such as the Research Center for Nuclear Physics (RCNP) in Japan and the ISIS Neutron and Muon Source in the U.K., , due to the following three properties: Nondestructive The penetration depth of the μ – depends on its momentum ( P μ ). P μ in the range between 8 and 50 MeV/c can be used for this technique in J-PARC.…”
