An LED-pumped 3-mJ TEM 00 Q-switched Nd:YLF laser

Leon Dauerer, F. Waßer, D. Schumacher, M. Roth et autres

We report, to the best of our knowledge, the first direct pumping of a millijoule-level Nd:YLF solid-state laser with high-power light-emitting diodes (LEDs), motivated by the demand for scalable, efficient, and cost-effective laser drivers for inertial confinement fusion (ICF). A Nd:YLF rod …

Enhancing Neutron Measurement Accuracy with Bubble Detectors at Laser-Driven Neutron Sources

Stefan Scheuren, M. A. Millán-Callado, Jonas Kohl, Tim T. Jäger et autres

Bubble detectors are widely used to measure neutron flux from laser-driven sources employing a pitcher-catcher setup, due to their insensitivity to intense $γ$-ray backgrounds and strong electromagnetic pulses (EMP).\\ This paper presents a method to account for the neutron energy-dependent response of …

Management of Material Redeposition Below and Above the Sample for Laser Micromachining of Laser Fusion Targets

N. R. Schott, Matthias Brönner, F. Richard Christ, Maximilian Hartmann et autres

Abstract Ultrashort pulse laser micromachining is a commonly used technique in the field of target fabrication for laser fusion experiments. In this context, material redeposition caused by ultrashort pulse laser ablation can greatly reduce the target quality. This work analyzes material redeposition …

Characterization of a mock up nuclear waste package using energy resolved MeV neutron analysis

Tim T. Jäger, T. Hirsh, Stefan Scheuren, Alexander Long et autres

Reliable radiographic methods for characterizing nuclear waste packages non-destructively (without the need to open containers) have the potential to significantly contribute to safe handling and future disposal options, particularly for legacy waste of unknown content. Due to required shielding of waste containers …

Particle swarm optimization of 1D isochoric compression designs for fast ignition

Matthias Brönner, S. Atzeni, Debra A. Callahan, Jim Gaffney et autres

A method to study isochoric compression to mass densities relevant for direct-drive fast ignition schemes is presented. The method is based on the combination of one-dimensional radiation-hydrodynamic simulations using the code MULTI-IFE [Ramis and Meyer-ter Vehn, Comput. Phys. Commun. 203, 226 (2016)] …
