We report on the optimization of a BremsStrahlung Cannon (BSC) design for investigation laser-driven fast electron populations in shock ignition relevant experimental campaign at Laser Megajoule-PETawatt Aquitaine facility. In this regime with laser intensities 1015 W/cm2–1016 W/cm2, electrons energies ?100 keV are expected to be generated through Stimulated Raman Scattering (SRS) and Two Plasm...

Abstract Proportional electroluminescence (EL) is the physical effect used in two-phase dark matter detectors, to optically record gas phase ionization signal produced by particle scattering liquid phase. In our previous works presence of a new EL mechanism noble gases, namely that neutral bremsstrahlung (NBrS), was demonstrated both theoretically and experimentally, addition ordinary due excim...

Experiments using proton beams at high luminosity colliders and fixed target facilities provide impressive sensitivity to new light weakly coupled degrees of freedom. With these experiments in mind, we revisit the production dark vectors scalars via bremsstrahlung, making use a model that describes underlying nucleon scattering cross-section forward direction due pomeron exchange. We compare re...

Abstract Relativistic electrons generated by the interaction of petawatt-class short laser pulses with solid targets can be used to generate bright x-rays via bremsstrahlung. The efficiency energy transfer into these depends on multiple parameters including focused intensity and pre-plasma level. This paper reports experimental results from a high glass at maximum 10 19 W cm ?2 . In-situ measur...

Experiments on the multiterawatt (MTW) laser at the Laboratory for Laser Energetics will study the effect of the focal-spot shape on the forward acceleration and collimation of electrons. A compact electron spectrometer has been developed to record the energy spectra of electrons ejected in the interaction of the laser at multiple angular locations simultaneously. The modular system with replac...
