High-intensity laser-plasma interactions are pivotal in advanced scientific research, with applications spanning fundamental physics to medicine. The ELIMAIA (ELI Multidisciplinary Applications of laser-Ion Acceleration) [1-3] beamline at the ELI Beamlines facility, part of the Extreme Light Infrastructure ERIC, offers a cutting-edge platform for studying laser-driven ion acceleration at high...
One of the fundamental goals of laser science is obtaining laser beams with larger and larger intensities. The most widely used methods for such are CPA (Chirped Pulse Amplification) and its derivatives, which are fundamentally limited due to LIDT (Laser Induced Damage Threshold) of components used. One of the solutions proposed is using SPM (Self Phase Modulation), which involves spectral...
This study aims at understanding the dependence of the E1 strength in the transition region from vibrational to rotational nuclei. The chosen method of study is the Nuclear Resonance Fluorescence method, a two-step photonuclear process which consists of the absorption of a photon and the subsequent resonant re-emission of gamma rays [1].
The experimental data has been acquired using...
The electromagnetic dipole response of $^{242}$Pu was studied for the first time using the nuclear resonance fluorescence (NRF) method, hence with real photons. The experiment was performed at TU Darmstadt, where monoenergetic electrons are provided by the superconducting Darmstadt linear electron accelerator S-DALINAC to produce bremsstrahlung by impinging on a gold radiator target. A sample...
The interest in laser-plasma accelerated particle beams with potential application in the biomedical field is rapidly growing [1, 2]. The future use of such beams greatly depends on the development of specially designed focusing and beam transport systems that can control the delivery of the beam with a predefined set of parameters [3]. Some of the main issues that need to be addressed,...
Energy-recovery linacs provide high beam currents with lower RF power requirements compared to conventional machines while maintaining the high beam quality of a linac. The S-DALINAC is a thrice-recirculating accelerator operating at a frequency of 3 GHz, that is capable of being operated as a multi-turn superconducting energy-recovery linac. Its efficiency is currently limited by the bunch...
Nanostructured targets have a bigger surface area compared to flat targets, which are the usually employed materials in high intensity, high power laser-matter interaction experiments. This allows to improve the interaction by enabling a stronger coupling of the laser with the targets, leading to a volumetric heating and an enhanced particle acceleration. Nickel nanowires and nanotubes were...
Laser-accelerated ions typically feature an exponential energy spectrum with a characteristic cut-off energy, a signature of target normal sheath acceleration (TNSA) [1]. However, the broad energy distribution inherent to TNSA poses a significant limitation for applications demanding well-defined ion energies, such as proton therapy [2] and the fast ignition concept in inertial confinement...
The giant dipole resonance (GDR) is one of the most fundamental nuclear excitations and it dominates the dipole response of all nuclei. Since its discovery in the early days of nuclear physics it has consistently attracted a great deal of attention. Its evolution from a single-humped structure in spherical nuclei to a double-humped one in deformed nuclei is considered one of the prime...
Photon-induced reactions provide unique data on nuclear fission due to their selectivity on excitations of low multipolarity and thereby contribute significantly towards a detailed microscopic description of the nuclear fission process. In particular, using quasi-monochromatic linearly-polarized photons to induce the fission process gives access to information about the nuclear energy...
The theoretical description of nuclear fission is a challenging quantum many body problem since it involves quantum tunneling of the nuclei through fission barriers. This tunneling is very sensitive to the collective inertia along the fission path. In most of the fission calculations, the collective inertia is evaluated using cranking approximation which neglects the dynamical residual...
In recent decades, the development of high-power lasers has increased interest in the use and research of laser-accelerated ions. While offering excellent characteristics, such as high brightness, high energies, and very short pulse duration, laser-accelerated ions also pose significant challenges regarding their capture and transport due to high initial divergence and a wide energy spectrum....
