Neutron Interferometers from Stacked Holographic Photopolymer Gratings
Saba Shams-Lahijani, Tobias Jenke, Juergen Klepp +2
Long-wavelength neutron interferometry using discrete optical elements is notoriously challenging due to stringent alignment and stability requirements. Here, we introduce a monoli…
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…

Elhoucine Hadden, Jürgen Klepp, Martin Fally +6
Nanoparticle-polymer composite gratings incorporating ultrahigh-refractive-index hyperbranched polymers as organic nanoparticles have demonstrated exceptional light optical propert…
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…
Photosensitive materials for neutron optics
Martin Fally, Juergen Klepp, Christian Pruner +6
Photosensitive materials with ever-improving properties are of great importance for optical and photonics applications. Additionally, they are extremely useful for designing compon…
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…
