One of the most promising cases of magnetic hyperthermia is using magnetic nanoparticles (MNPs) in cancer therapy. In this treatment, MNPs are immersed into tumours and, by heating with external magnetic fields, typically 100-900 kHz, destroy cancer cells. Since it is a clinical application, optimising field parameters and the heating power is crucial to maintain both safety and high...
LumaCam detectors have a structure resembling many established scintillator-based imaging detectors. The key difference is the imaging chip being fast enough to identify the individual scintillaton photons produced by a neutron interaction in the scintillator screen. This information can be used to provide enhanced spatial and temporal resolution, as well as noise suppression and particle...
To increase neutron flux on small samples, we are developing a nested mirror optic (NMO) array for the PUMA thermal triple-axis spectrometer. This device is intended to reduce the beam size to 5 mm x 5 mm while preserving 50% of the incoming neutrons, resulting in an 8-fold increase in the flux available for small samples. However, the complex neutron flight paths generated from novel optics...
Within the DAPHNE4NFDI consortium MLZ has been working on providing a FAIR data access option. The central part will be the MLZ datacatalogue ( which should be available before the Usermeeting).
We will show how the data in the catalogue look like, how you can really access it and a give an outlook on the coming data access options.
An existing ELN solution, the “Workbench”, ran as a prototype around the clock from September 2023 to June 2024. Due to the overall slow loading times with high data and user load, a new application has been under development since December 2023. While its frontend is heavily inspired by “Workbench”, the backend has been completely rewritten. It has the working title MLZ-ELN and has been...
Polarized neutron diffraction is proven to be a powerful tool for studies of magnetic structure and microscopic dynamics of matter. This is assured by the success of the XYZ-polarization analysis technique, which lays the basis for separation of coherent, incoherent, and magnetic contributions to the scattering cross section. Even though polarized diffraction can provide a more robust...
Recent developments of scintillator-based event-driven detectors have opened up the possibility of utilizing AI to identify single neutron events from sparse data readout. A crucial aspect for AI-based event detection is to provide training datasets that can be utilized to accurately train a neural network. Such training datasets require a “ground-truth” to avoid errors in the event...
Small-angle neutron scattering is useful for probing nanometer-scale structures but inhomogeneous materials like ball-milled powders used for hydrogen storage often yield fairly featureless diffraction patterns that are difficult to interpret [1]. Despite this, such patterns can still reveal important information. To explore this, Aslan et al. conducted an in situ investigation, measuring...
Neutron imaging with cold and thermal neutrons typically use scintillator screens that use lithium-6 as a neutron converter. Compared to lithium-6, boron-10 offers nearly four time higher neutron absorption cross-section and larger daughter products that deposit their energy locally, offering the potential for higher neutron capture efficiency and spatial resolution. Screens were fabricated...
