Development of Nuclear Emulsions for Muography

Trends in Publishing Muography Related Research: The Situation at the End of 2020

“…JAIS-292, 2022 While the bulk of the earlier literature focused on applications, more and more papers from 2010 onwards have had a more technical approach. Publications of this kind concentrate on detector designs [43,44,45,46,47], software codes and simulation toolkits [48,49,50,51], algorithms [52,53,54], and comparison studies [55,56,57]. It can be anticipated that this type of research continues for many years to come as continuous development of tools and methodologies is an essential part of the development of muography.…”

“…This paper is a multidisciplinary geosciences publication [6]. Before 2021, the top ten peak years in publications have been 2019 (68 articles), 2020 (61), 2016 (53), 2015 (47), 2014 (45), 2013 (44), 2017 (44), 2018 (36), 2012 (33), and 2009 (27). More than one publication represents every year after 2000 (Figure 2).…”

“…By using the categories of the WoS, the four most prominent research fields so far have been Instruments Instrumentation (164 articles), Nuclear Science Technology (147), Physics Particles Fields (114), and Physics Nuclear (104). After these four categories, there is a notable gap before Engineering Electrical Electronic (60), Physics Applied (59), Multidisciplinary Sciences (56), Geosciences Multidisciplinary (50), Physics Multidisciplinary (47), and Radiology Nuclear Medicine Medical Imaging (42) (Figure 5). The number of different WoS categories is 59.…”

Hidden chamber discovery in the underground Hellenistic necropolis of Neapolis by muography

“…The emulsion films used for this experiment were produced at Nagoya University. Each films is 25 × 30 cm 2 and consists of two sensitive layers, 70 µ m thick each, deposited on both sides of a 175 µm thick polystyrene base 11 . AgBr crystals have a diameter of about 200 nm and the expected grain density for minimum ionizing particles tracks is on average about 40 grains per 100 µ m path.…”

Muography, Outreaching, and Transdisciplinarity: Toward the Golden Age of Muography

“…The muon detector geometries, shapes, and sizes are by necessity varied to carry out muography in absorption and scattering modes and in different physical environments (e.g., surface, underground, borehole, underwater, and airborne). There are also a multitude of variations in muon detection itself as this can be done, for example, with plastic scintillators [3], nuclear emulsions [4], drift chambers [5], micro-mesh gaseous structures [6], resistive plate chambers [7], and multiwire proportional chambers [8].…”
