Neutron Imaging

Dear Colleagues,

Neutron imaging is a fast-developing field that has benefited from both extensive developments in instrumentation and new applications. On the one hand, relatively inexpensive but still very useful neutron imaging and tomography facilities can be installed in small reactors and even in laboratory neutron sources. On the other hand, a handful of sophisticated facilities at major neutron research centers are pushing the limits of the state-of-the-art by reaching a spatial resolution of well under 10 micrometers, a time resolution of well under milliseconds, and unmatched sensitivity.

Instrumentation developments continue to improve all aspects of neutron imaging, from sources to beam optics to detectors. Examples include lab neutron sources from Adelphi and Phoenix Nuclear Lab; grating interferometry for improved sensitivity, especially for porous and granular matter; focusing optics for increased signal rate and resolution; and improved scintillators. Modern computational methods allow limited-angle tomography and the potential restoration of blurred images due to relatively low neutron intensity. The range of applications is extending from studying minute details in Li-batteries’ electrodes with the help of cold neutrons to utilizing fast-neutron resonances for studies of nuclear materials and national security applications.

This Special Issue will report on recent breakthroughs in instrumentation and new applications in this exciting field that extends from lithium batteries to studies of cultural heritage, and from biomedical engineering to nuclear materials.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Imaging is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
