AI and We in the Future in the Light of the Ouroboros Model: A Plea for Plurality

AI, 2022
Artificial Intelligence (AI) is set to play an ever more important role in our lives and societies. Here, some boundary conditions and possibilities for shaping and using AI as well as advantageously embedding it in daily life are sketched.

Neutron Imaging at Compact Accelerator-Driven Neutron Sources in Japan

Journal of Imaging, 2018
Neutron imaging has been recognized to be very useful to investigate inside of materials and products that cannot be seen by X-ray. New imaging methods using the pulsed structure of neutron sources based on accelerators has been developed also at compact

Downscattered neutron imaging

Review of Scientific Instruments, 2004
Images with 14 MeV neutrons of inertial confinement fusion (ICF) D,T fusion show the regions of most intense fusion burn, while images based on lower-energy “downscattered” neutrons can reveal regions of nonburning D,T fuel. The downscattered images can help to understand ICF implosion dynamics.

Electric Field Imaging Using Polarized Neutrons

Physical Review Letters, 2020
We experimentally demonstrate that electrically neutral particles, neutrons, can be used to directly visualize the electrostatic field inside a target volume that can be isolated or occupied. Electric-field images were obtained using a polychromatic, spin-polarized neutron beam with a sensitive polarimetry scheme.

Thermal neutron backscatter imaging [PDF]

IEEE Symposium Conference Record Nuclear Science 2004., 2005
Objects of various shapes, with some appreciable hydrogen content, were exposed to fast neutrons from a D-T generator, resulting in a partially-moderated spectrum of backscattered neutrons. The thermal component of the backscatter was used to form images of the objects by means of a coded-aperture thermal-neutron imaging system. Timing signals from the

Connection between f-electron correlations and magnetic excitations in UTe2

npj Quantum Materials
The detailed anisotropic dispersion of the low-temperature, low-energy magnetic excitations of the candidate spin-triplet superconductor UTe2 is revealed using inelastic neutron scattering. The magnetic excitations emerge from the Brillouin zone boundary

Neutron phase filtering for separating phase- and attenuation signal in aluminium and anodic aluminium oxide

Scientific Reports
Neutron imaging has gained significant importance as a material characterisation technique and is particularly useful to visualise hydrogenous materials in objects opaque to other radiations.
