Three‐dimensional density structure of La Soufrière de Guadeloupe lava dome from simultaneous muon radiographies and gravity data

open access: yesGeophysical Research Letters, 2017
Muon imaging has recently emerged as a powerful method to complement standard geophysical tools in the understanding of the Earth's subsurface. Muon measurements yield a “radiography” of the average density along the muon path, allowing to image large ...

Feasibility of three-dimensional density tomography using dozens of muon radiographies and filtered back projection for volcanos [PDF]

open access: yesGeoscientific Instrumentation, Methods and Data Systems, 2018
This study is the first trial to apply the method of filtered back projection (FBP) to reconstruct three-dimensional (3-D) bulk density images via cosmic-ray muons.

A new cylindrical detector for borehole muon radiography

open access: yesNuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2023
Muons of cosmic origin have a great capability to penetrate through matter. This property is exploited in muon radiography, also known as muography, a technique which allows to highlight the presence of discontinuities of the mass density in the subsoil such as cavities, tunnels or rock masses. A detector of cylindrical geometry, optimized for borehole

A Multi Institutional Comparison of Imaging Dose and Technique Protocols for Neonatal Chest Radiography [PDF]

open access: yes, 2019
Published ArticleIntroduction: The focus on paediatric radiation dose reduction supports reevaluation of paediatric imaging protocols. This is particularly important in the neonates where chest radiographs are frequently requested to assess respiratory

Possible application of compact electronics for multilayer muon high-speed radiography to volcanic cones [PDF]

open access: yesGeoscientific Instrumentation, Methods and Data Systems, 2013
Compact data-taking electronics were developed for high-speed multilayer muon radiography in order to minimize operation failure rates. By requiring a linear trajectory within the position sensitive detectors (PSDs), the background (BG) events produced ...

Radiography - How do students understand the concept of radiography?

open access: yes, 2014
Background: Radiography as a concept has mainly been associated with the functional role of the radiographer. The concept has been studied from a theoretical point of view.

Adopting a blended approach to learning: experiences from radiography at Queen Margaret University, Edinburgh [PDF]

open access: yes, 2009
The perspective of the radiography teaching team at Queen Margaret University (QMU) was that a transmission mode of programme delivery was sub-optimal in helping students to learn and make links between theory and practice.

Measurement of the top-quark pair production cross section with soft muon b-tagging in pp collisions at [Square root] s = 7 TeV with the Atlas detector [PDF]

open access: yes, 2011
PhDThis thesis presents a study of the measurement of the top pair production cross section in the semileptonic decay channel with soft muon b-tagging at the Atlas detector using early LHC data.

GEANT4 Simulations of the ISIS Muon Target at Rutherford Appleton Laboratory [PDF]

open access: yes, 2009
MuSR science requires the availabilty of intense beams of polarised positive muons. At the ISIS pulsed muon facility at Rutherford Appleton Laboratory the muons are generated from a low Z thin slab graphite target inserted in the proton beam.

Air shower simulation for background estimation in muon tomography of volcanoes [PDF]

open access: yesGeoscientific Instrumentation, Methods and Data Systems, 2013
One of the main sources of background for the radiography of volcanoes using atmospheric muons comes from the accidental coincidences produced in the muon telescopes by charged particles belonging to the air shower generated by the primary cosmic ray ...
