The ever-growing need for radiopharmaceuticals, i.e., compounds containing pharmaceutical drugs and radioisotopes used for medical diagnostic imaging (SPECT/PET scan) and treating neoplasms, is significantly leading to an increased demand for such su

Plasma wakefields driven by high power lasers or relativistic particle beams can be orders of magnitude larger than the fields produced in conventional accelerating structures. Since the plasma wakefield is composed not only of accelerating but also

Beam dumps are indispensable components for particle accelerator facilities to absorb or dispose beam kinetic energy in a safe way. However, the design of beam dumps based on conventional technology, i.e., energy deposition via beam–dense matter in

Abstract This work analyses the counterpropagation of transversal plane waves in a linear, homogeneous, nondispersive, and isotropic medium. Although this is a traditional subject in disciplines associated with wave phenomena, a propagation analysis

We review the fundamentals of electron beam generation in self-modulated laser wakefield acceleration (SM-LWFA) using laser pulses with peak powers on the TW and sub-TW scale. The results of several new particle-in-cell simulations for λ = 0.8 µm a

Electron beams generated by laser wakefield acceleration can induce a photoneutron reaction to convert 100Mo into 99Mo. Multi-pC, several-MeV electron beams, obtained from particle-in-cell simulations, could generate bremsstrahlung gamma photons with

This work presents a short review on the advances of plasma beam dump modelling since they have been first proposed. Analytical models have been derived to estimate the beam energy loss for both passive and active beam dump schemes. For the passive c
