Commissioning measurements for a very cold neutron interferometer based on nanodiamond-polymer composite gratings
Roxana H. Ackermann, Sonja Falmbigl, Elhoucine Hadden +7
Over the past decade, holographic nanodiamond-polymer composite gratings have been developed and optimized as high-efficiency diffractive elements for very cold neutrons (VCN), for…
Further search for magnetic-field-induced neutron disappearance in an ultracold neutron beam
Gaby Brenot, Benoit Clément, Hanno Filter-Pieler +7
We report the results of the second iteration of an experiment searching for neutron-hidden-neutron oscillations in a beam of ultracold neutrons, conducted at the PF2 facility of t…
Fundamental Nuclear and Particle Physics At Neutron Sources
H. Abele, J. Amaral, W. R. Anthony +121
Fundamental neutron and neutrino physics at neutron sources, combining precision measurements and theory, can probe new physics at energy scales well beyond the highest energies pr…
Application of nanodiamond-polymer composite holographic gratings in a very cold neutron interferometer
Sonja Falmbigl, Roxana H. Ackermann, Elhoucine Hadden +6
In recent decades, photosensitive materials have been used for the development of optical devices not only for light, but also for cold and very cold neutrons. We show that hologra…
High-Density Ultracold Neutron Source for Low-Energy Particle Physics Experiments
Skyler Degenkolb, Estelle Chanel, Simon Baudoin +19
SuperSUN, a new superthermal source of ultracold neutrons (UCN) at the Institut Laue-Langevin, exploits inelastic scattering of neutrons in isotopically pure superfluid He at t…
