Additive manufacturing using the fused deposition modeling (FDM) allows to easily and inexpensively manufacture complex geometries using 3D printers. Typical base materials are thermoplastics such as polylactic acid (PLA) or acrylonitrile butadiene styrene (ABS). Recently, the availability of 3D printers has increased significantly, enabling the widespread use of additive manufacturing by...
With the advancement of artificial intelligence and machine learning methods, autonomous approaches are recognized to have great potential for performing more efficient TAS experiments. In our view, it is crucial for such approaches to provide thorough evidence about respective performance improvements in order to increase acceptance within the community. Therefore, we propose a benchmarking...
Optimization of computation time has always been a challenge in the world of computation. In this work, we address the computation of X-Ray and neutron scattering data from molecular dynamics simulations. There are multiple software solutions available for this; we have chosen sassena for our work. Sassena inherits distributed memory parallelization (MPI) from its previous version. This work...
We propose a method for kinetic neutron reflectometry with a time resolution of a few µs. The method is based on periodic excitation of the sample and phase locked modulation of the beam intensity by one radio frequency spin flipper, and requires a position sensitive neutron detector with time resolution also in the order of 1 µs. The output are time resolved reflectivity curves locked to the...
The MIEZE technique relies on a fast sinusoidal neutron intensity modulation up to the MHz range, generated by the rotation of the neutron spin in radio-frequency spin flippers, and subsequent conversion to an intensity modulation by a spin analyzer.
This intensity modulation is washed out due to the neutron velocity dispersion.
By carefully choosing the rotation frequencies as well as the...
In the last two years we improved our understanding of sputtering process parameters leading to (Ni,Ti) supermirror coatings with reduced mechanical stress and higher reflectivity. This knowledge has been applied to the case of non-depolarizing m=2 (Cu,Ti) supermirrors, which have been successfully prepared with the standard DC magnetron sputtering facility of the FRM II neutron optics group....
The preservation of food is one of the most important tasks in food processing. A typical application is lyophilisation or freeze drying and refers to the sublimation of ice to vapour below the triple point. Lyophilisation is employed for dehydrating biopharmaceuticals and high-value foods in frozen state as the structural and nutritional attributes are not affected by the process in contrast...
Recently developed event-driven detectors are capable of registering spots of light induced by neutron interactions in scintillator materials. Reconstructing the Center-of-Mass of the individual interactions, it is possible to significantly enhance spatial and temporal resolution of recorded radiographs. Utilizing this principle, we present a detector capable of Time-of-Flight imaging with an...
The study of hydrogen diffusion and storage in different materials is crucial in the challenge of an actual implementation of sustainable energy sources, but also to explore the possible modification of electronic, magnetic and optical properties of the host materials. Due to high sensitivity of neutrons to hydrogen atoms, neutron scattering techniques have been successfully used for many...
