“…With the upcoming of new high-repetition rate, high-power, short pulse user facilities, like the Extreme Light Infrastructure ALPS 18 , it becomes imperative to find strategies for mitigation and control of EMP and related detrimental effect. Mitigation options include: shielding of electronic devices with Faraday cages; using shielded cables; disabling and electrically decoupling devices during the laser shot; placing sensitive equipment far away from the interaction area; development of a dedicated grounding for susceptible devices, shielding the target 19 and ensuring a good electrical isolation of the target. On the other hand the understanding of physical phenomena behind the generation of EMP, could lead to new generation laser driven radio-frequency (RF) sources, which is of strong interest for space industries (satellite instrumentation protection) and novel fusion energy schemes 20,21 .…”

Recent advances on laser technology have enabled the generation of ultrashort (fs) high power (pW) laser systems. for such large scale laser facilities there is an imperative demand for high repetition rate operation in symbiosis with beamlines or end-stations. in such extreme conditions the generation of electromagnetic pulses (eMp) during high intense laser target interaction experiments can tip the scale for the good outcome of the campaign. The EMP effects are several including interference with diagnostic devices and actuators as well as damage of electrical components. the eMp issue is quite known in the picosecond (ps) pulse laser experiments but no systematic study on eMp issues at multi-Joule fs-class lasers has been conducted thus far. In this paper we report the first experimental campaign for EMP-measurements performed at the 200 TW laser system (VEGA 2) at CLPU laser center. eMp pulse energy has been measured as a function of the laser intensity and energy together with other relevant quantities such as (i) the charge of the laser-driven protons and their maximum energy, as well as (ii) the X-ray K α emission coming from electron interaction inside the target. Analysis of experimental results demonstrate (and confirm) a direct correlation between the measured EMP pulse energy and the laser parameters such as laser intensity and laser energy in the ultrashort pulse duration regime. numerical feM (finite element Method) simulations of the eMp generated by the target holder system have been performed and the simulations results are shown to be in good agreement with the experimental ones.

“…By designing and controlling the interaction geometry to reduce [372] and mitigate [373] EMP generation, many general techniques [374] appropriate for 'single-shot' operation [375] can be delivered at high repetition rates ( 10 Hz) with suitable retuning/redesign and the replacement of the detector element or by transporting the signal to a more benign environment [376] before digitization (see Figure 41). Scintillators, phosphors and transducers capable of kHz-GHz rates can be readily coupled to gated or rep-rated high-dynamic-range detectors.…”

In the 2015 review paper ‘Petawatt Class Lasers Worldwide’ a comprehensive overview of the current status of high-power facilities of ${>}200~\text{TW}$ was presented. This was largely based on facility specifications, with some description of their uses, for instance in fundamental ultra-high-intensity interactions, secondary source generation, and inertial confinement fusion (ICF). With the 2018 Nobel Prize in Physics being awarded to Professors Donna Strickland and Gerard Mourou for the development of the technique of chirped pulse amplification (CPA), which made these lasers possible, we celebrate by providing a comprehensive update of the current status of ultra-high-power lasers and demonstrate how the technology has developed. We are now in the era of multi-petawatt facilities coming online, with 100 PW lasers being proposed and even under construction. In addition to this there is a pull towards development of industrial and multi-disciplinary applications, which demands much higher repetition rates, delivering high-average powers with higher efficiencies and the use of alternative wavelengths: mid-IR facilities. So apart from a comprehensive update of the current global status, we want to look at what technologies are to be deployed to get to these new regimes, and some of the critical issues facing their development.

“…A simple method for mitigation of the EMP emission from targets used for laser proton acceleration was proposed in Ref. [164]. The idea is to confine the emitted electromagnetic radiation in a limited volume, capture a large portion of the electrons ejected from the target and dissipate the trapped electromagnetic energy with an electric resistor.…”

This paper provides an up-to-date review of the problems related to the generation, detection and mitigation of strong electromagnetic pulses created in the interaction of high-power, high-energy laser pulses with different types of solid targets. It includes new experimental data obtained independently at several international laboratories. The mechanisms of electromagnetic field generation are analyzed and considered as a function of the intensity and the spectral range of emissions they produce. The major emphasis is put on the GHz frequency domain, which is the most damaging for electronics and may have important applications. The physics of electromagnetic emissions in other spectral domains, in particular THz and MHz, is also discussed. The theoretical models and numerical simulations are compared with the results of experimental measurements, with special attention to the methodology of measurements and complementary diagnostics. Understanding the underlying physical processes is the basis for developing techniques to mitigate the electromagnetic threat and to harness electromagnetic emissions, which may have promising applications.
