We demonstrate an all-optical method for generating ultrashort, spectrally narrow proton beams using an intense laser interaction with a helical target structure. Direct measurements reveal proton pulse durations of only tens of picoseconds, substantially shorter than those obtained from conventional targets at comparable energies. This temporal compression observed is as a result of a...
We report on updates on the comprehensive processing of PIC simulations on HPC systems at LRZ using tools for the data management of large parameter studies of physics simulations. Our example study uses a Particle-In-Cell code by Prof. Ruhl et al (LMU) to explore the laser plasma interaction and ensuing particle acceleration of polysterene or hydrogen micro-targets in the micrometer range....
In this talk, we report on several novel aspects of laser-driven electron acceleration at CALA. The main highlight is the demonstration of energy doubling and a record absolute energy-transfer efficiency from the LWFA to the PWFA stages in hybrid laser–plasma wakefield acceleration (LPWFA). The motivation behind this scheme is to overcome the emittance limits inherent to classical...
A Galilean electromagnetic particle-in-cell (GEM-PIC) algorithm that reformulates the complete Maxwell and Vlasov equations in a Galilean-boosted coordinate frame s developed. This transformation preserves the full electro-magnetic dynamics of the interaction while leveraging scale separation to improve computational efficiency. In contrast to quasistatic approaches, GEM-PIC does not require...
Laser–plasma accelerators promise a compact alternative to conventional radio-frequency accelerators, but achieving simultaneously high charge, high stability, and scalability at high repetition rates remains a major challenge. Here, we demonstrate that self-modulated laser wakefield acceleration (SM-LWFA) driven by picosecond laser pulses provides a robust pathway to generate electron...
