Background and purpose: The impact of intrafractional motion and deformations on clinical radiotherapy delivery has so far only been investigated by simulations as well as point and planar dose measurements. The aim of this study was to combine anthr

Background and purpose: Three-dimensional dosimetry of proton therapy (PT) with chemical dosimeters is challenged by signal quenching, which is a lower dose-response in regions with high ionization density due to high linear-energy-transfer (LET) and

The magnetic field in magnetic resonance imaging guided radiotherapy (MRgRT) delivery systems influences charged-particle trajectories and hence the three-dimensional (3D) radiation dose distributions. This study investigated the dose-response as wel

Intrafractional motion and deformation influence proton therapy delivery for tumours in the thorax, abdomen and pelvis. This study aimed to test the dose–response of a compressively strained three-dimensional silicone-based radiochromic dosimeter d

The ultrafast dynamics of short-pulse-laser-excited fused silica is investigated by measuring polarization-resolved reflectances of a wavelength-tunable probe pulse following a near-infrared pump pulse. These data, which should, in principle, allow t

We observe and characterize two nonlinear light-amplification regimes with unique spectral properties and fluence dependencies in laser-excited fused silica using ultrafast pump-probe imaging spectroscopy. The two underlying mechanisms are switchable

Tin-containing nanocrystals, embedded in silicon, have been fabricated by growing an epitaxial layer of Si1−x−ySnxCy, where x = 1.6 % and y = 0.04 % on a silicon substrate, followed by annealing at various temperatures ranging from 650 ∘C to 90
