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…
Holographic hyperbranched polymer nanocomposite grating with exceptionally large neutron scattering length density modulation amplitudes
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…
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…
