Ultracold Neutron Sources: An Essentially Enhanced Optimal Operation Temperature for Ortho-Deuterium-Based Superthermal Converters
Erik Walz, Christoph Morkel
There is a longstanding dogma in the physics of ultracold neutrons (UCN): The optimal temperature of ortho-deuterium based UCN-sources must not exceed . This value h…
Direct measurement of the scattering cross sections of liquid ortho-deuterium for ultracold neutrons and comparison with model calculations
Stefan Döge, Jürgen Hingerl, Winfried Petry +1
Liquid deuterium is a fluid between the quantum and classical regimes. It attracts interest from fundamental research for the verification of quantum calculations but also from neu…
Incoherent approximation for neutron up-scattering cross sections and its corrections for slow neutrons and low crystal temperatures
Stefan Döge, Chen-Yu Liu, Albert Young +1
The incoherent approximation (IA) is often used for calculating the one-phonon inelastic neutron scattering cross section for arbitrary solids. It is valid for thermal neutrons but…
Scattering of ultracold neutrons from rough surfaces of metal foils
Stefan Döge, Jürgen Hingerl, Egor V. Lychagin +1
The transparency of metal foils for ultracold neutrons (UCNs) plays an important role in the design of future high-density UCN sources, which will feed a number of fundamental phys…
Measured velocity spectra and neutron densities of the PF2 ultracold-neutron beam ports at the Institut Laue--Langevin
Stefan Döge, Jürgen Hingerl, Christoph Morkel
Ultracold neutrons (UCNs) are a useful tool for fundamental physics experiments. They can be used to probe the lifetime of free neutrons, search for new CP violating processes and…
Scattering cross sections of liquid deuterium for ultracold neutrons: Experimental results and a calculation model
Stefan Döge, Christian Herold, Stefan Müller +7
We present scattering cross sections of ultracold neutrons (UCN) in liquid deuterium at T = 20.6 K, as recently measured by means of a transmission experiment. The…
