11. EMP monitoring and debris mitigation in the P3 chamber at ELI Beamlines

Dr Tomas Lastovicka (ELI Beamlines)

In an experimental campaign in December 2021, the HAPLS laser at ELI Beamlines delivered up to 10 J pulses in both single shot and 3.3 Hz regimes. The campaign was used to test various debris protection shields and to monitor laser-plasma intensity levels through EMP measurements. In the contribution, we also summarize EMP effects on electronics used in the P3 experimental chamber.

12. Electro-Magnetic Pulse Measurements at the VEGA Laser Facility

Dr Michael Ehret (CPLU)

We present and compare experimental studies of electromagnetic pulses (EMP) produced by the interaction of relativistic laser pulses at intensities of several 10^20 W/cm^2 with solid density targets. Passive calibrated B-field antennas with large bandwidth from 9 kHz to 400 MHz are used to detect electromagnetic pulses and excited cavity modes triggered by the laser-plasma interaction.

13. EMP Based Alignment in Laser Based Acceleration Systems

Dr Aurelian Marcu (INFLPR)

Alignment is a critical issue in laser acceleration techniques. A laser-target system is usually mechanically prealigned and further alignment optimizations are performed by optical methods (use of a test beam, CCD viewing cameras and so on). However, these methods are generally used successfully in low power laser regime. As laser power increases, most existing alignment techniques become...
