Observations and modeling of scintillation in the vicinity of a polar cap patch
Journal of Space Weather and Space Climate, 2022 Small-scale ionospheric plasma structures can cause scintillation in radio signals passing through the ionosphere. The relationship between the scintillated signal and how plasma structuring develops is complex.

Indirect X-ray detectors with single-photon sensitivity
Journal of Synchrotron Radiation, 2022 The new generation of synchrotron light sources are pushing X-ray detectors to their limits. Very demanding conditions with unprecedented flux and higher operating energies now require high-performance X-ray detectors combining sensitivity, efficiency ...

Scintillation in Low-Temperature Particle Detectors
Physics, 2021 Inorganic crystal scintillators play a crucial role in particle detection for various applications in fundamental physics and applied science. The use of such materials as scintillating bolometers, which operate at temperatures as low as 10 mK and detect

Scintillation Increase Induced by Focusing (Invited)
Photonics, 2023 We show that the focusing of a random electromagnetic beam by a lens gives rise to a scintillation index at the geometrical focus that generally differs from that of the incident beam.

A Review of Inorganic Scintillation Crystals for Extreme Environments
, 2021 In the past, the main research and use of scintillators in extreme environments were mainly limited to high energy physics and the well-logging industry, but their applications are now expanding to reactor monitoring systems, marine and space exploration,

On the Relationship between Low Latitude Scintillation Onset and Sunset Terminator over Africa
Remote Sensing, 2021 The solar terminator is a moving boundary between day-side and night-side regions on the Earth, which is a substantial source of perturbations in the ionosphere. In the vicinity of the solar terminator, essential parameters like S4 index measurements are

Towards the possibility to combine LOFAR and GNSS measurements to sense ionospheric irregularities
Journal of Space Weather and Space Climate, 2023 Inhomogeneities within the ionospheric plasma density affect trans-ionospheric radio signals, causing radio wave scintillation in the amplitude and phase of the signals.
