“…The irradiation time of each sample was approximately 5 h. Three high-purity-germanium semiconductor detectors: GL0110 (CANBERRA), GLP 36360 (ORTEC), and GMX20P4 (ORTEC) were set around the vacuum chamber covering different energy ranges of 0-250 keV, 0-500 keV, and 0-4000 keV, respectively. The detailed experimental setup is shown in our previous papers [8,9]. Figure 1 shows the energy spectrum of the GLP36360 detector for the muon irradiation of the K 3 [Fe(CN) 6 ] sample.…”

Muon irradiation experiments were performed on two iron compounds with different valences of the central metal (K 3 [Fe(CN) 6 ] and K 4 [Fe(CN) 6 ]3H 2 O), and muonic X-rays from these compounds were measured. The muon capture probability to each atom and muonic X-ray structure were investigated in detail. Differences in intensities of X-rays of muon nitrogen and muon capture on iron were observed between the two compounds.

“…[15][16][17] used Muon Induced X-ray Emission (MIXE), while the Ref. [18] used Muonic Atom X-ray Spectroscopy (MAXRS); all of which describe the same technique), a non-destructive technique, which was developed more than 40 years ago [14,[19][20][21], has recently been used extensively with pulsed muon beams for elemental analysis [16,18,[22][23][24][25][26][27][28][29][30][31][32][33][34]. The advantage of this technique is that it is able to probe deep into the material, up to a few millimeters, and does not lead to a severe radiation damage of the sample.…”

The toolbox for material characterization has never been richer than today. Great progress with all kinds of particles and interaction methods provide access to nearly all properties of an object under study. However, a tomographic analysis of the subsurface region remains still a challenge today. In this regard, the Muon Induced X-ray Emission (MIXE) technique has seen rebirth fueled by the availability of high intensity muon beams. We report here a study conducted at the Paul Scherrer Institute (PSI). It demonstrates that the absence of any beam time-structure leads to low pile-up events and a high signal-to-noise ratio (SNR) with less than one hour acquisition time per sample or data point. This performance creates the perspective to open this technique to a wider audience for the routine investigation of non-destructive and depth-sensitive elemental compositions, for example in rare and precious samples. Using a hetero-structured sample of known elements and thicknesses, we successfully detected the characteristic muonic X-rays, emitted during the capture of a negative muon by an atom, and the gamma-rays resulting from the nuclear capture of the muon, characterizing the capabilities of MIXE at PSI. This sample emphasizes the quality of a continuous beam, and the exceptional SNR at high rates. Such sensitivity will enable totally new statistically intense aspects in the field of MIXE, e.g., elemental 3D-tomography and chemical analysis. Therefore, we are currently advancing our proof-of-concept experiments with the goal of creating a full fledged permanently operated user station to make MIXE available to the wider scientific community as well as industry.

“…On the other hand, the PGAA and NAA techniques are bulk measurements and not depth-sensitive, and the sensitivity is strongly isotope dependent. The technique of Muon-Induced X-ray Emission (MIXE), a non-destructive technique, which was developed more than 40 years ago [14,15,16,17], has recently been used extensively with pulsed muon beams for elemental analysis [18,19,20,21,22,23,24,25,26,27,28,29,30,31]. The advantage of this technique is that it is able to probe deep into the material, up to a few millimeters, and does not lead to a severe radiation damage of the sample.…”
